It’s too difficult to find fittings for 9948
Thread Content
Hydrogen pipelines with a pressure of ≤4.7 Mpa and DN100 size; they are designed as GC1 type pipelines. The pipes are made of 9948 seamless steel, and the fittings are also made of 9948 or 5310 steel. Unfortunately, the available quantities of these materials are too small to meet the demand; even if it were possible to obtain them, 8163 steel would have to be used as a substitute. Has anyone encountered this situation? How can it be solved?
Hello, our company can supply pure material pipe fittings that meet the 9948 5310 standards; we can discuss this further if there is any interest
It’s easy to purchase. Every project we undertake is useful; I’ve never heard of a situation where it’s not possible to get it. It’s not allowed to use 8163 pipes and fittings in place of GC1 pipes – substitution is not permitted
