As a rule, our seamless drawn high-pressure pipes are stainless and are made according to our specifications . All high-pressure pipes are checked according to strict regulations for strength, cracks, chemical composition, dimensions, etc. On request a relevant 3.1B certificate can also be furnished. To achieve higher fatigue strength, our high-pressure pipes are provided with high-pressure connections (58° taper and left-hand thread) and cold-worked on customer request. Standard lengths are usually 6-7 m, though on request other lengths are also available. Please indicate the following information after the order number of the respective pipe when ordering conduit nipples with high-pressure connections on both sides:

- KG/KG (for taper on both sides / thread)
-100 (length in mm, here as an example 100mm)

On request we also supply ready-machined (e.g. bent according to drawing, provided with taper and thread on both sides and subsequently cold-worked) pipes.

* The operating pressure is designed here for predominantly static load and a temperature of 20°C. In the case of high dynamic load (e.g. pulsating pressure) as well as at higher temperatures, the permissible pressure must be reduced. The amount of the reduction depends on the number of load changes, among other things. We would be glad to advise you on this.

All pipes are provided with a taper of 58° and a left-hand thread (see figure). The tools necessary for this are also available from us (category 7 – Tools). The dimensions are shown in the table below.

High-pressure pipes may only be bent with special bending tools. Conventional bending tools usually have bending radii that are too small and thus damage the high-pressure pipes (hairline cracks). The bending radius must correspond to at least 7 times the outside diameter of the pipe. You will find bending tools for high-pressure pipes in category “7 – Tools”. High-pressure pipes must never be heated over 400°C.
