Non-destructive testing of steel tubes - Part 5: Magnetic particle inspection of seamless and welded ferromagnetic steel tubes for the detection of surface imperfections (ISO 10893-5:2011)
ISO 10893-5:2011 specifies requirements for magnetic particle inspection of seamless and welded ferromagnetic steel tubes for the detection of surface imperfections on the tube body and the end/bevel face at the ends.
For the tube body, it specifies requirements for the detection of surface imperfections on all or part of the outside surface of tubes. However, by agreement between the purchaser and manufacturer, it can be applicable to the inside surface over a limited length from the ends of tubes, dependent on the tube diameter.
In addition, ISO 10893-5:2011 can be used, as appropriate, to locate the position of external surface imperfections detected by another non-destructive testing method (e.g. ultrasonic) prior to dressing of the tube surface, and to ensure complete removal of the imperfection after dressing is complete.
For the end/bevel face at the ends of plain-end and beveled-end tubes, ISO 10893-5:2010 specifies requirements for the detection of laminar imperfections which can interfere with subsequent fabrication and inspection operations (e.g. welding and ultrasonic inspection of the welds).
ISO 10893-5:2011 is applicable to the detection of imperfections, other than laminar imperfections, on the end/bevel face. In this case, magnetization is applied in the direction essentially perpendicular to the orientation of the particular imperfections being detected.
It can also be applicable to the testing of hollow sections.
Zerstörungsfreie Prüfung von Stahlrohren - Teil 5: Magnetpulverprüfung nahtloser und geschweißter ferromagnetischer Stahlrohre zum Nachweis von Oberflächenunvollkommenheiten (ISO 10893-5:2011)
Dieser Teil der ISO 10893 legt die Anforderungen an die Magnetpulverprüfung nahtloser und geschweißter ferromagnetischer Rohre zum Nachweis von Oberflächenunvollkommenheiten am Rohrkörper und an den Stirnflächen/Stirnflächenanschrägungen der Rohrenden fest. Für den Rohrkörper werden Anforderungen zum Nachweis von Oberflächenunvollkommenheiten auf der gesamten oder in Teilbereichen der Rohraußenoberfläche festgelegt. Nach Vereinbarung zwischen Besteller und Hersteller kann es auch auf die Prüfung der Innenoberfläche, in Abhängigkeit vom Rohrdurchmesser über eine begrenzte Länge von den Rohrenden aus, angewendet werden. Zusätzlich darf dieser Teil der ISO 10893, soweit zweckmäßig, zur Lokalisierung der Lage äußerer Oberflächenunvollkommenheiten, die durch andere zerstörungsfreie Prüfverfahren nachgewiesen wurden (z. B. durch Ultraschallprüfung), vor der Nachbearbeitung und zur Sicherstellung der vollständigen Entfernung der Unvollkommenheiten angewendet werden. Für die Stirnflächen/Stirnflächenanschrägungen von Rohren mit glatten oder angeschrägten Enden legt dieser Teil der ISO 10893 Anforderungen zum Nachweis von Dopplungen fest, die die nachfolgende Rohrfertigung und -prüfung (z. B. Schweißen, Ultraschallprüfung der Schweißstöße usw.) beeinträchtigen können. Dieser Teil der ISO 10893 darf auch für den Nachweis von anderen Unvollkommenheiten als Dopplungen an den Stirnflächen bzw. Stirnflächenanschrägungen angewendet werden. In diesem Fall muss im Wesentlichen senkrecht zur Hauptorientierung der nachzuweisenden Unvollkommenheiten magnetisiert werden. Dieses Dokument kann auch für die Prüfung von Hohlprofilen angewendet werden.
Essais non destructifs des tubes en acier - Partie 5: Contrôle par magnétoscopie des tubes en acier ferromagnétique sans soudure et soudés pour la détection des imperfections de surface (ISO 10893-5:2011)
L'ISO 10893-5:2011 spécifie les exigences relatives au contrôle par magnétoscopie des tubes en acier ferromagnétique sans soudure et soudés pour la détection des imperfections de surface sur le corps du tube et sur les faces d'extrémité ou les chanfreins aux extrémités.
Pour le corps du tube, elle spécifie les exigences relatives à la détection des imperfections de surface sur tout ou partie de la surface extérieure des tubes. Cependant, par accord entre l'acheteur et le producteur, elle est applicable à la surface intérieure sur une longueur limitée à partir des extrémités des tubes, selon le diamètre du tube.
En outre, l'ISO 10893-5:2011 peut être utilisée, le cas échéant, pour déterminer l'emplacement d'imperfections sur la surface extérieure détectées par une autre méthode de contrôle non destructif (par exemple par ultrasons), avant réparation de la surface des tubes et pour garantir l'élimination complète de l'imperfection après réparation.
Pour les faces d'extrémité ou les chanfreins aux extrémités des tubes à extrémités lisses ou chanfreinées, l'ISO 10893-5:2011 spécifie les exigences relatives à la détection des dédoublures pouvant avoir une incidence sur les opérations de fabrication et de contrôle ultérieures (par exemple soudage ou contrôle par ultrasons des soudures).
L'ISO 10893-5:2011 est aussi applicable à la détection des imperfections autres que des dédoublures sur les faces d'extrémité ou les chanfreins. Dans ce cas, la magnétisation est à appliquer essentiellement perpendiculairement à l'orientation des imperfections particulières à détecter.
Elle est également applicable au contrôle des profils creux.

Ta del ISO 10893 določa zahteve za ugotavljanje površinskih napak nevarjenih in varjenih feromagnetnih jeklenih cevi na telesu cevi in koncih/poševninah na koncih z magnetnimi delci. Za telo cevi določa zahteve za odkrivanje površinskih napak na celotni zunanji površini cevi ali njenem delu. Po dogovoru med kupcem in proizvajalcem lahko velja tudi za omejeno dolžino notranje površine od koncev cevi, odvisno od premera cevi. Poleg tega se ta del ISO 10893 lahko uporablja, kot je ustrezno, za iskanje mest napak na zunanji površini, odkritih z drugo neporušitveno preskusno metodo (npr. ultrazvočno) pred apretiranjem površine cevi, in za zagotavljanje popolne odstranitve napak po zaključku apretiranja. Za konce/poševnine na koncih ravnih in poševnih cevi ta del ISO 10893 določa zahteve za odkrivanje laminarnih napak, ki lahko motijo nadaljnje operacije izdelave in pregleda (npr. varjenje in ultrazvočni pregled varov). Ta del ISO 10893 velja za odkrivanje napak, razen laminarnih napak, na koncu/poševnini. V tem primeru se magnetizacija uporabi v smeri, pretežno pravokotni na smer konkretnih napak, ki se odkrivajo. Lahko velja tudi za preskušanje votlih delov.

Overview
EN ISO 10893-5:2011 - Magnetic particle inspection of seamless and welded ferromagnetic steel tubes - defines requirements for the non-destructive testing (NDT) of steel tubes to detect surface imperfections on the tube body and on end/bevel faces. The standard applies to both seamless and welded ferromagnetic tubes and can be used to verify defects found by other NDT methods (e.g., ultrasonic) or to confirm their removal after dressing.
Key topics and requirements
- Scope of inspection
- Detection of surface imperfections on the outside surface of tube bodies (whole or partial circumference).
- Can be applied to the inside surface near tube ends by purchaser-manufacturer agreement (length depends on diameter).
- Applicable to end/bevel faces for detection of laminar and non-laminar imperfections that may affect welding or inspection operations.
- Applicable to hollow sections where appropriate.
- Magnetization and technique
- Uses magnetic particle inspection (MPI) with a.c. or d.c. magnetization depending on the technique chosen.
- For end/bevel faces, magnetization direction is oriented essentially perpendicular to the defect orientation when detecting non-laminar imperfections.
- Use of dry magnetic powder on end/bevel faces only by prior agreement.
- Preparation and timing
- Inspection normally carried out after completion of primary production processes (rolling, heat treatment, sizing, straightening, etc.).
- Surfaces must be clean and free of oil, scale, grease or other contaminants that could mask indications.
- Personnel and qualification
- Operators must be trained and qualified per ISO 9712, ISO 11484 or equivalent; NDT operations authorized by a level 3 NDT individual as required.
- Evaluation and documentation
- Contains requirements for evaluation of indications, acceptance criteria and test reporting to ensure consistent interpretation and traceability.
Practical applications and users
- Who uses this standard:
- Tube manufacturers and quality departments to set NDT inspection procedures and acceptance criteria.
- Third-party inspectors and NDT service providers performing MPI on steel tubes.
- Purchasers and specifiers (oil & gas, petrochemical, mechanical engineering) who require surface integrity verification before fabrication or welding.
- Typical use cases:
- Production control on seamless and welded ferromagnetic tubes.
- Locating and verifying surface defects found by ultrasonic or other NDT methods.
- Ensuring end preparation (bevels) are free of laminar defects that could compromise welding or downstream inspections.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

imperfections
1 Scope
This part of ISO 10893 specifies requirements for magnetic particle inspection of seamless and welded
ferromagnetic steel tubes for the detection of surface imperfections on the tube body and the end/bevel face
at the ends.
For the tube body, it specifies requirements for the detection of surface imperfections on all or part of the
outside surface of tubes. However, by agreement between the purchaser and manufacturer, it can be
applicable to the inside surface over a limited length from the ends of tubes, dependent on the tube diameter.
In addition, this part of ISO 10893 can be used, as appropriate, to locate the position of external surface
imperfections detected by another non-destructive testing method (e.g. ultrasonic) prior to dressing of the tube
surface, and to ensure complete removal of the imperfection after dressing is complete.
For the end/bevel face at the ends of plain-end and beveled-end tubes, this part of ISO 10893 specifies
requirements for the detection of laminar imperfections which can interfere with subsequent fabrication and
inspection operations (e.g. welding and ultrasonic inspection of the welds).
This part of ISO 10893 is applicable to the detection of imperfections, other than laminar imperfections, on the
end/bevel face. In this case, magnetization is applied in the direction essentially perpendicular to the
orientation of the particular imperfections being detected.
It can also be applicable to the testing of hollow sections.

The article discusses EN ISO 10893-5:2011, a standard that specifies requirements for magnetic particle inspection of seamless and welded ferromagnetic steel tubes. The standard focuses on detecting surface imperfections on the tube body and the end/bevel face at the ends. It covers the detection of imperfections on the outside surface of tubes, and in some cases, the inside surface as well. The standard can also be used to locate external surface imperfections detected by other non-destructive testing methods, such as ultrasonic testing. It also specifies requirements for detecting laminar imperfections on the end/bevel face, which can interfere with subsequent fabrication and inspection operations. The standard can also be used for the detection of imperfections, other than laminar imperfections, on the end/bevel face. Additionally, it may be applicable to testing hollow sections.
ISO 10893-5: 2011は、表面の欠陥を検出するための無欠陥鋼管の磁粉検査の要件を規定する国際規格です。この規格は、管体と管端部の断面における表面の欠陥を検出することに焦点を当てています。鋼管の管体に対しては、外側表面全体または一部における表面の欠陥検出の要件を規定しています。ただし、管径に応じて購入者と製造者の間で合意があれば、内部表面にも適用できます。また、他の非破壊検査法（超音波など）によって検出された外部表面の欠陥の位置を見つけるためにも適用できます。また、表面の処理が完了した後に欠陥が完全に除去されたことを保証するためにも使用できます。平面端と面取り端の管末部においては、後続の加工や検査作業（溶接や溶接部の超音波検査など）に干渉する可能性のある層状の欠陥の検出要件を規定しています。ISO 10893-5: 2011は、層状の欠陥以外の欠陥の検出にも適用できます。この場合、検出対象の欠陥の方向に対して基本的に垂直な方向に磁化が適用されます。また、中空部の検査にも適用できます。
ISO 10893-5:2011은 무구멍 강관의 자기 입자 검사를 위한 요구 사항을 명시하는 국제 표준입니다. 강철 관의 표면 결함 감지를 위해 관 몸체와 끝 부분 / 경사면의 표면 결함을 검출하기 위한 요구 사항을 명시합니다. 관 몸체에 대해서는, 관 외부 표면의 전체 또는 일부에 대한 표면 결함의 검출을 위한 요구 사항을 명시합니다. 그러나 관 지름에 따라 구매자와 생산자 사이의 합의에 따라 유한한 길이의 관 끝 부분에서 내부 표면에 적용될 수도 있습니다. 또한, 다른 비파괴 검사 방법 (예: 초음파)로 검출가능한 외부 표면 결함의 위치를 찾기 위해 사용될 수 있으며, 표면 처리 후 결함이 완전히 제거되었는지 확인하기 위해서도 사용될 수 있습니다. 일자 개구부 외에 경사면과 단순 개구부 말단에 대해서는, ISO 10893-5:2010은 이후의 가공 및 검사 작업 (예: 용접 및 용접 부위의 초음파 검사)에 방해되는 층상 결함의 검출을 위한 요구 사항을 명시합니다. ISO 10893-5:2011은 층상 결함 외에도 각종 결함을 검출하기 위해 적용될 수 있습니다. 이 경우, 축화 결함의 방향에 대해 기본적으로 수직 방향으로 자성화가 적용됩니다. 또한 이 국제 표준은 중공 섹션의 검사에도 적용될 수 있습니다.
