Measures to prevent stratification of right-angle square steel tube billets in industrial projects
Sometimes, stratification problems may occur in right-angle square steel tube billets, resulting in non-conformity in flaw detection. To prevent this defect, we can take the following three measures: (I) Optimize slow cooling time Optimize the slow cooling process of right-angle square steel tube...Read more -
Fields and characteristics of seamless steel pipes commonly used in industrial projects
Seamless steel pipe is a hollow long steel strip, usually made of carbon steel, stainless steel, alloy steel, and other materials. Due to its excellent properties such as high strength, corrosion resistance, and high temperature resistance, it is widely used in the petroleum, chemical industry, e...Read more -

Benefits of plastic-coated steel pipes
In today’s rapidly developing industrialization and urbanization process, pipelines are an important infrastructure for transporting fluids, and their performance and safety have attracted much attention. Plastic-coated steel pipes, a new type of pipe that combines the strength of steel pip...Read more -
Eight major defect characteristics and causes of industrial seamless steel pipes
1. Folding of seamless steel pipes It is a state that exists on the outer or inner surface of seamless steel pipes in a straight or spiral shape, continuous or discontinuous. The main reason for the folding is that the quality of the pipe material is poor, there are folds in itself, or there are ...Read more -
What is the difference between hot-rolled galvanized steel sheets and cold-rolled galvanized steel sheets
1. Cost Because there is one less process than cold-rolled substrate, the production cost of hot-rolled substrate galvanizing is lower than that of cold-rolled substrate, mainly annealing cost and cold-rolling rolling cost, and the other processes are similar. 2. Quality performance Because the h...Read more -
Can 304 hot-rolled stainless steel plate be bent
304 stainless steel (06Cr19Ni10) is a steel developed based on 302 stainless steel (12Cr18Ni9). Its performance is similar to 302 stainless steel, but its corrosion resistance is better than 302 stainless steel. It can be used as welded parts with thin cross-sections. It is the stainless steel wi...Read more -
How to control the wall thickness deviation of seamless steel pipes
Among the common problems of seamless steel pipes, wall thickness difference (eccentricity) occupies the first place. Wall thickness difference, as the name implies, is the difference between the maximum wall thickness and the minimum wall thickness. As long as it is a seamless steel pipe, there ...Read more -
Explore the high quality of A106 seamless steel pipe
A106 seamless steel pipe, one of the most watched products in the steel industry, contains many mysteries worth exploring. Let’s take a deep look at the meaning of this keyword and unveil its mystery. 1. Features of A106 seamless steel pipe: - High strength: A106 seamless steel pipe has exc...Read more -
Analysis of the Causes of Surface Cracks on Industrial Small-Diameter Seamless Stainless Steel Pipes
Observing the crack morphology, the cracks extend obliquely at an angle of 45° to the inner wall. Since the pipe itself has good mechanical properties and high ductility, it can be ruled out that it is caused by cold rolling. The crack width develops from coarse to fine, and a bifurcation appears...Read more -
What are the detection methods for oil casing
Oil casing is a high-end product produced by steel pipes. There are many types of casings, and there are many types and requirements for the buckle types of casing ends. The buckle types that can be processed include STC, LC, BC, VAM, etc. The production and installation process of oil casing inv...Read more -
The purpose of preheating the spiral steel pipes before welding
Important components of alloy steel and thick parts must be preheated before welding. The purpose of preheating before welding is as follows: (1) Preheating can slow down the cooling rate after welding, allowing hydrogen to diffuse and escape in the weld metal, avoiding cracking caused by hydroge...Read more
