Carbon steel tubes consist of an iron and carbon alloy that is able to be bent into shapes during manufacture without reducing its high tensile strength. It is important to protect the steel surface from corrosion due to the iron ferrite composition that will rust through oxidization from water contact. The pipework that supplies fire sprinkler systems is often…
Read MoreIn the process of heat treatment of seamless pipes, various defects will occur due to improper process measures or various other factors, and the existence of these defects directly affects the performance of steel pipes. 1. Crack Heat treatment cracks mainly include quenching cracks, tempering cracks and grinding cracks. When heating some large-sized steel parts and alloy billets, if…
Read More1.Improve the anti-corrosion conditions of the medium In order to improve anti-corrosion conditions, the following two methods can be used for cs seamless pipes. ①Remove harmful components in the medium. For example, boiler water is heated to boiling, and then the oxygen is removed before use. ②Add corrosion inhibitor. Corrosion inhibitor is a substance that can slow down the…

Read More1. Grinding of thick-walled seamless nozzle: After cutting, use an angle grinder to grind the plastic layer of the nozzle. Its purpose is to prevent the plastic layer from melting or even burning during the flange welding process, damaging the pipe, and grinding the nozzle plastic layer with an angle grinder. 2. Thick-walled seamless pipe plastic coating treatment:After polishing,…
Read MoreThe problem of uneven wall thickness of large-diameter seamless steel pipes is relatively common in the production of seamless steel pipes, and it is also a headache for customers. The unevenness of the thick-walled seamless steel pipe is mainly reflected in the uneven spiral wall, the uneven linear wall thickness, and the thickness of the head and tail is…
