Steel pipe quality problem
Surface quality problems of steel pipe mainly shows in the surface oxide thick,surface cracking,surface re-skin, surface mechanical pumps and so on.After the completion of hot-rolled carbon steel cold rolled steel and then heat treatment or after, it will form a thick and strong adhesion, high te...Read more -
Which elements in the production of steel pipes will affect the performance
According to the quality and performance of steel pipes, we have summarized the properties of different metal elements contained Carbon:The higher the carbon content the higher the hardness of the steel nine but the worse the plasticity and toughness. Sulfur: It is a harmful impurity in steel pip...Read more -
Difference between ERW and SAW steel pipe
ERW is a electric-resistance welded steel pipe, Resistance welded steel pipe is divided into exchange of welded steel pipe and DC welded steel pipe in two forms. AC welding in accordance with different frequencies are divided into low-frequency welding, IF welding, welding of ultra-IF and high-...Read more -

What is cartoon steel pipe
The steel with slight quantity of elements other than carbon,silicon,sulphur and manganeses is called carbon steel. These are the alloyed iron with carbon as main constituent.The amount of carbon content in the steel pipe determines its hardness and strength but on other hand it makes the steel ...Read more -
Advantages of Galvanized Pipes
Advantages of galvanized pipes is following below: Firstly, galvanized pipe after being hot dip galvanized surface can be protected, and inside the cavity of the pipe or any other coating the corner is difficult to enter, deepen the zinc can easily cover to the top, make whole galvanized pipe can...Read more -
Three production processes of welded pipe
Steel pipe is generally divided into seamless steel pipe and welded steel pipe according to production methods. This time we mainly introduce welded steel pipe,that is,welded steel pipe.Its production is to bend the tube blank (steel plate and steel strip into the required cross-section shape and...Read more -

Deformation strengthening of high-pressure alloy pipe
High-pressure alloy pipe deformation strengthening is using the method of deformation of steel reinforcement. Also known as the strain hardening or work hardening. The strength of the material at the macro (or a whole) the ability to resist deformation (or flow stress). Hardness is the ability of...Read more -
What is the difference between seamless steel pipe and seamed steel pipe
(1) seamless steel pipe is generally rolled from carbon steel or low-alloy structural steel, is the earliest application of steel pipe material, its cross-sectional area is larger, the unit area under pressure is smaller. (2) Seamed steel pipes are mainly used to transport fluids. Due to the manu...Read more
