Suppliers and manufacturer of Grade B70 CL22 LSAW Pipes with Exceptional sizes, standard, and Quality
ASTM A672 Grade B70 Pipe is a low carbon steel pipe that is meant for high pressure applications at moderate temperatures. The specification has electric fusion welded pipes. Multi Metals (India) is a leading manufacturer and supplier of the ASTM A672 Grade B70 Pipe in various dimensions and grades. The pipes are made from pressure vessel grade plates by welding them with filler materials under electric fusion welding.
Due to this method, the A672 B70 Carbon Steel EFW Pipes are of larger diameters. They can be welded with most conventional methods. Since these are for low to moderate temperature operations, the pipes don’t have to be high temperature tolerance. However, the A672 Grade B70 LSAW Pipes have to undergo preheating before welding with high temperature welding procedures. To avoid welding cracks on the pipes, they also have to be post weld heat treated.
The dimensions of the pipes range from 12 inches to 64 inches in outer diameter with different classes ranging from class 10 to class 73 and different schedules ranging from sch10 through XXS. The ASTM A672 B70 CL22 Pipes can come in different lengths varying from single random, double random to custom lengths up to 14m. For unique application requirements the pipes also have different pipe end types such as beveled, plain and threaded. Please feel free to contact us for the pricing and more product detail of the ASTM A672 GR.70 Boiler Pipes and others.
