What is BS EN 295-7 - VCP requirements for pipe jacking about?
Pipejacking involves non-disruptive installation of underground pipelines. BS EN 295-7 is a European Standard that discusses vitrified clay pipe (VCP) systems for drains and sewers.
BS EN 295-7 is the seventh part of the VCP systems for drains and sewers multi-series, and specifies requirements for vitrified clay pipes and joints for pipe jacking for buried drain and sewer systems for the conveyance of wastewater (including domestic wastewater, surface water, and rainwater) under gravity and periodic hydraulic surcharge or under a continuous low head of pressure.
Pipe jacking techniques include micro-tunneling, pipe-eating, pipe bursting, and where appropriate lining with discrete pipes.
Note: Corresponding provisions for the evaluation of conformity (ITT and FPC) and sampling and those for the test methods are further specified in EN 295-2 and EN 295-3, respectively.
Who is BS EN 295-7 - VCP requirements for pipe jacking for?
BS EN 295-7 on VCP requirements for pipe jacking is useful for:
- Manufacturers and suppliers of vitrified clay pipes
- Product design / innovation teams
- Quality control / testing personnel
- The construction industry
- Builders / architects / real estate developers
- Contractors
- Civil engineers
Why should you use BS EN 295-7 - VCP requirements for pipe jacking?
VCP is commonly used in gravity sewer collection mains because of its long life and resistance to almost all domestic and industrial sewage.
BS EN 295-7 also specifies requirements for rubber, polyurethane, polypropylene, stainless steel, and other materials used for joints for pipe jacking.
BS EN 295-7 provides guidance on requirements for pipes for pipe jacking, materials, manufacture, water absorption, appearance, dimensions, deviation from straightness, bending tensile, compressive, jacking strength, chemical resistance, as well as long-term thermal stability.
In addition, durability, reaction to fire, dangerous substances, designation, marking, and evaluation of conformity are discussed in BS EN 295-7.
BS EN 295-7 guides you with manufacturing high-quality sewage system components, which extends the life of a sewage system and reduces the need for costly dig-ups.
What’s changed since the last update?
BS EN 295-7:2013 supersedes BS EN 295-7:1996 and, together with BS EN 295-1:2013, BS EN 295-2:2013, BS EN 295-4:2013, BS EN 295-5:2013, and BS EN 295-6:2013, it supersedes BS EN 295-10:2005, which is withdrawn. The main changes with respect to the previous edition are listed below:
- Nominal sizes DN 900, DN 1 200, and DN 1 400 added
- Requirements for the determination of jacking strength changed
- Requirements for the resistance to high-pressure water jetting added
- Reaction to fire added
