EN 14457:2004 - General requirements for components specifically designed for use in trenchless construction of drains and sewers

Overview

EN 14457:2004 is a CEN European Standard that specifies general requirements for pipes and joints designed for trenchless construction of drains and sewers - principally the methods known as pipe jacking, microtunnelling and pilot jacking (as defined in EN 12889). It covers components used in gravity systems (pressures up to 40 kPa) and points to EN 773 when hydraulically pressurised systems (above 40 kPa) are relevant. EN 14457:2004 is intended as a general basis for preparing or revising product standards and as a reference when no product standard exists; it is not a product evaluation or installation technique standard.

Key topics and technical requirements

The standard establishes functional and dimensional expectations for jacking pipes and their joints, including:

  • Scope of use
    • Domestic wastewater, rainwater, surface water and other non-damaging industrial wastewaters.
  • Dimensional requirements
    • Specified nominal sizes (DN): 150, 200, 225, 250, 300, 400, 500, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000.
    • Tolerances on internal and external diameters, straightness, squareness of pipe ends and pipe length tolerances.
  • Hydraulic and geometric performance
    • Internal bore smoothness, continuity of invert (joint step limits), and appearance free of defects affecting hydraulics.
  • Joint design
    • Joints must ensure tightness, lateral stability, and transfer of longitudinal compressive/tensile forces; pressure transfer rings where applicable.
  • Mechanical and durability properties
    • Ring stiffness, load-bearing capacity (crushing strength, modulus of elasticity, bending strengths), abrasion resistance, jetting resistance and long-term behaviour.
  • Tightness and temperature
    • Gravity-system tightness: internal and external water pressure tests at 50 kPa.
    • Continuous water discharge temperature suitability: 45 °C (DN ≤ 200) and 35 °C (DN > 200).
  • Tests and marking
    • Specifies measurement and testing categories: diameter/wall thickness, straightness, squareness, invert continuity, water/air tightness and other relevant tests.

Applications and users

EN 14457:2004 is used by:

  • Standards writers and product specifiers to develop detailed product standards when none exist.
  • Pipe manufacturers to define design, joint systems, tolerances and declared jacking loads.
  • Project engineers, designers and asset owners preparing specifications for trenchless sewer and drain installations.
  • Contractors and installation supervisors who need compatibility requirements between pipes and jacking equipment.

Practical benefits include consistent component specifications for trenchless installation, improved compatibility with jacking equipment, clearer joint performance expectations, and guidance on durability and hydraulic performance.
