ASTM A106 GR. B/ASME SA106 GR. B/API 5L GR. B Carbon Steel Seamless Pipe/Tube
For Manufacture heating-pipelines, containers, coal-saving devices, superheaters and reheaters of high pressure boiler

The difference between precision steel pipe and seamless pipe
1.The seamless steel tube with obvious difference is that dimensional accuracy, can be up to 0.1mm.
2.High precision steel pipe diameter surface finish, the customer without processing can be used
Directly and ordinary seamless steel tube to the customer and lather, polishing processing.

ASTM A106 GR.B/ASME SA106 GR.B/API 5L GR.B Carbon Steel Seamless pipe Features
1.The smaller outer diameter
2.High precision to do small batch production
3.Cold drawn finished products of high precision, good surface quality
4.The steel pipe transverse area is more complex
5.Steel pipe is superior performance, dense metal
