According to the introduction of seamless steel tube manufacturers in Zhejiang, there are many kinds of steel pipes, and the production process is different. Production of steel pipe is not as simple as we imagine.

As for steel to withstand the pressure to the hydraulic test, to test its ability and quality, leakage, soaked or expansion for qualified does not occur at the prescribed pressure. Some steel pipes according to the buyers requirement of standard or edge test, flaring test, flattening test etc..

 Zhejiang seamless steel tube manufacturers introduce to you the following several common steel pipe differences.

Seamless steel pipe

Seamless steel tube is ingot or billet made by solid capillary hole, then hot, cold or cold made. Standard Specification for seamless steel pipe with external diameter * wall thickness mm. Seamless steel tubes for hot rolling and cold rolling (DIAL) seamless steel tubes two.

Two, Cold rolling (DIAL) seamless steel pipe

Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube.

Three, Hot-rolled seamless steel tube

Hot rolled seamless steel tubes are divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipes, etc..

Yes, it is these three kinds: seamless steel tube, cold rolling (DIAL) seamless steel pipe, hot-rolled seamless steel pipe is our usual common types of steel pipe. And no matter what kind of steel pipe, we at Anji Peng Da are able to provide.
