ASME SA179 seamless steel pipe standard specification covers seamless cold drawn low carbon steel pipe for tubular heat exchanger, condenser and other similar heat transfer equipment. The outside diameter of ASME SA179 seamless steel pipe is 1 / 8 "to 3

The material of 20# seamless steel tube is 20# steel, the strength is slightly higher than that of 15 steel, with little quenching and no tempering brittleness. Cold deformation has high plasticity and is generally used for bending, rolling, edge bending

20# seamless steel pipe is made of steel ingot or solid tube blank by piercing, then hot rolling, cold rolling or cold drawing.
What is the difference between 20# seamless steel pipe and seamless steel pipe?
There are four differences between 20# seamle

Compression type: Insert the piping of C45 seamless steel pipe into the nozzle of the fitting, fasten it with a nut, and compress the sleeve of the mouth of the C45 seamless steel pipe with a spiral force through a seal ring, which acts as a seal to compl
