ASTM A234 standard steel pipe fittings have been widely applied in pipeline systems, it includes carbon and alloy steel material. Grades in ASTM A234: ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on. In these standard Grade WPB is the most common material used for medium and high temperature…
Read MoreThe difference between carbon steel seamless tube and stainless steel seamless tube mainly refers to the difference in design rules between carbon steel and stainless steel, which means that the design rules of these two types of steel cannot be used in common. These differences are summarized as follows: Carbon steel 1. Ordinary steel is carbon steel, that is,…
Read MoreClassification by steel pipe material: Steel pipes can be divided into: carbon steel pipes, alloy steel pipes, stainless steel pipes, etc. Carbon pipes can be divided into ordinary carbon steel pipes and high-quality carbon structural pipes. Alloy tubes can be divided into: low alloy tubes, composite tubes, financial tubes, high-strength tubes, precision alloys (such as Kovar) tubes, and high-temperature…
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 More1) Can seamless steel tube be galvanized? Seamless steel tube refers to a steel pipe that is perforated from a whole round steel and has no welds on the surface. It is widely used. Ordinary galvanized pipes are generally made of welded pipes. Can seamless steel tubes be galvanized? The answer is To be sure, galvanizing treatment is to…
Read MoreThere are two types of galvanizing methods for seamless tubes: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing includes wet method, dry method, lead-zinc method, redox method, etc. The main difference between different hot-dip galvanizing methods is what method is used to activate the surface of the pipe body after acid dip cleaning of the steel pipe to improve the quality…
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…
