Helical bending

Manufacture of streamlined coils and pressure vessels:

CEPHI, through its recognized experience in the design and manufacture of heat exchangers, is also supplier of coils (stainless steel, steel and others on request).

We are able to realize for you, exchange coils subject or not to the pressure directive DESP2014 / 68-EU and the manufacturing codes such as CODAP-ASME-EN13445, etc … These coils can be equipped with end flanges or any other device allowing their commissioning – male end caps, gas sleeves, clamps, etc …

In the case of regulated equipment or on demand, these coils, if they are soldered by welding due to their length, will be made by qualified welders, following welding processes established and validated by an approved organization . We also provide inspection by a COFREND II controller and mechanical strength tests (hydraulic test), if required by regulation or on request. Other types of tests or checks may also be conducted – Helium leak tests, radiographic checks of welds.

A complete file containing all the useful documents can be produced – Plans, welding book including QMOS, QS, material certificates, reports of the
