Steel tubes and fittings for onshore and offshore pipelines - External liquid applied polyurethane and polyurethane-modified coatings
The standard defines the requirements of liquid applied external coating, polyurethane (PUR) and polyurethane-modified (PUR-MOD), for the corrosion protection of tubes and pipeline fittings.
The coating in this standard can be applied to longitudinally or spirally welded and to seamless steel tubes and fittings used for the construction of pipelines for conveying liquids or gases.
In accordance with the elongation properties, if the component has to be cold bent the coating shall be applied after bending unless otherwise approved by the purchaser.
The coating shall consist normally of one layer of liquid product, applied by brush or by an airless spray technique.
Other application methods can be recommended by the product manufacturer, in accordance with the kind of product (spatula, injection, spreading, etc.).
This coating can be used for the protection of buried or submerged steel tubes for service at the following temperatures and with two thickness classes A (1000 *m) and B (1500 *m) based on the following combination.
Lower thickness can be agreed between the coating manufacturer and the purchaser.
- type 1 : - 20 °C to 40 °C, thickness class A or B
- type 2 : - 20 °C to 60 °C, thickness class B
- type 3 : - 20 °C to 80 °C, thickness class B
Other temperatures can be agreed; in this case, tests shall be carried out at the required temperature.
In this standard the word components is used for tubes and fittings.
Frequencies of tests on fittings shall be agreed by the parties at the ordering stage.
Components coated with these types of coatings may be further protected by means of cathodic protection.
Stahlrohre und -formstücke für On- und Offshore-verlegte Rohrleitungen - Umhüllung (Außenbeschichtung) mit Polyurethan und Polyurethan-modifizierten Materialien
Diese Europäische Norm legt die Anforderungen an die Umhüllung mit flüssig aufgebrachtem Polyurethan (PUR) und Polyurethan-modifiziertem Material (PUR-MOD) für den Korrosionsschutz von Rohren und Formteilen fest.
Nach dieser Norm kann die Umhüllung auf längs- und spiralgeschweißten sowie auf nahtlose Stahlrohre und Formteile zum Bau von Rohrleitungen für die Beförderung von Flüssigkeiten und Gasen aufgebracht werden.
Bei der Kaltbiegung von Stahlteilen muss die Beschichtung in Abhängigkeit ihren Dehneigenschaften nach dem Biegevorgang aufgebracht werden, wenn vom Besteller nicht anders vorgegeben.
Die Umhüllung muss normal aus einem einschichtigen Auftragen eines Flüssigprodukts bestehen; das Auftragen erfolgt mittels Streichen oder im Airless-Spritzverfahren.
Andere Auftragsarten (wie Spachteln, Vergießen, Streichen, usw.) können vom Hersteller je nach Art des Produktes empfohlen werden.
Der Einsatz dieser Umhüllung kann zum Schutz von erd- oder wasserverlegten Rohren bei folgenden Betriebstemperaturen, aufgegliedert nach zwei Klassen, Klasse A (1000 µm) und Klasse B (1500 µm), wie folgt erfolgen. Geringere Schichtdicken können zwischen Besteller und Hersteller vereinbart werden.
Typ 1: -20 °C bis 40 °C Schichtdicke Klasse A oder
Typ 2: -20 °C bis 60 °C Schichtdicke Klasse B
Typ 3: -20 °C bis 80 °C Schichtdicke Klasse B
Andere Temperatureinsatzbereiche können vereinbart werden; in diesem Fall müssen für die gewünschten Temperaturen Prüfungen durchgeführt werden.
In dieser Norm gilt der Begriff �Teile" für Rohre und Formteile.
Bei Auftragserteilung muss für die Formteile die Häufigkeit der durchzuführenden Prüfungen von den Vertrags-schließenden bei der Auftragsvergabe festgelegt werden.
Mit einer solchen Umhüllung versehene Teile können zusätzlich kathodisch geschützt werden.
Tubes et raccords en acier pour canalisations enterrées et immergées - Revêtements externes en polyuréthanne ou polyuréthanne modifié liquides
La présente norme définit l'application de revêtements externes à base de polyuréthanne (PUR) et de polyuréthanne modifié (PUR-MOD) liquides, pour la protection anti-corrosion des tubes et raccords de canalisations. Dans la présente norme, le revêtement peut être appliqué à des tubes en acier soudés en long ou en hélice ou sans soudure et raccords utilisés pour la construction de canalisations de transport de fluides liquides ou gazeux.
