Common steel defects and related terms are introduced by seamless pipe manufacturers as follows: 1. Roundness: the circular section of the rolled material, such as the cross section of round steel and round steel pipe, the degree of diameter difference in each direction 2. Due to unreasonable mold design or manufacture, improper extrusion process, mold and extrusion cylinder, lubrication,…
Read MoreThe seamless pipe means a hollow section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with ordinary seamless pipes, stainless steel seamless pipes have higher corrosion resistance, and the finish is better than ordinary seamless steel pipes. But this does not mean…
Read MoreThere are many kinds of steel pipes on the market, such as: seam pipes, seamless pipes, etc., but many people do not know the difference, so what is the difference between seamed steel pipes and seamless steel pipes? The seam pipe is also called welded steel pipe, which is nominally named in nominal size. Its commonly used nominal size…

Since the customer’s project design was not completely determined, Xinyue made an estimated quotation for the materials required by the customer…
Read MoreCarbon 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…
