p235gh Flange

Check p235gh Steel Collar Flanges Dimensions & p235gh Pipe Price list

p235gh Pipe and flanges are according to this European specification that applies for boilers heat exchangers and pressure vessels. Rajveer Stainless And Alloys is a manufacturer and supplier of flanges. Flanges are objects that are used maintain pipes and fittings on a rail with a projecting rim. The p235gh Steel Collar Flanges have a collar that gets more grip on the surface on the attachment, usually with another flange or fitting where it is installed. The Carbon Steel P235gh Flange material is suitable for high temperature services. The material is a normalized carbon steel with sulfur, nitrogen, copper, niobium, titanium and manganese in its composition. The p235gh Material therefore has high corrosion resistance and high temperature resistance.

p235gh Flange

Leading Manufacturer of Carbon Steel P235gh Flange & p235gh Material

It is also stronger than most ordinary stainless steel materials. For these reasons, the flanges of this grade of material are used in oil and gas industries and in petrochemical industries by fabricators. The p235gh pipe flange materials produced by us are of superior quality and have long lifespans. It has relatively less yield strength and tensile strength than the P265GH material but has lower carbon content and higher manganese. This composition makes the p235gh blind flange applicable with heavily welded and corrosive environments. You can get a list of different types of flanges and pricing from us. Please contact us for further information.

P235gh flange applications and what is 1.0345 steel?

The European specification P235GH is a specification for pressure vessels, heat exchangers and boilers. The 1.0345 steel is a carbon steel. It is produced so that wrought products could be derived from it. The material is a non-alloyed material. The specification covers low thermal conductive alloys of carbon steel or non-carbon steels. The P235GH could be used under elevated temperatures and it is used in making flanges too. This material has carbon, manganese, sulfur, nitrogen, copper, niobium and titanium in its composition. This combination makes it stronger and corrosion resistant as well. So the material is suitable for flanges like any other strong material.
