Compared with seamless pipe, galvanized pipe and other steel, welded pipe has some outstanding characteristics. First of all, it is very simple to judge whether there is weld on the steel surface. Because the welded pipe is made by welding, it has obvious characteristics. Secondly, the diameter of welded pipe is generally large, and the diameter of seamless pipe and galvanized pipe is relatively small. Therefore, api 5l psl1 grade x42 standard, welded pipe is generally used in underground pipeline to transport water, gas, air, oil and heating steam with low pressure.

The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

Compared with thick steel plates, api 5l psl1 grade x42 standard, thin steel plates have many obvious advantages in steel plate processing and use. It is precisely these advantages of thin steel plates that make them more and more popular in various industries. First, compared to those thicker steel plate materials, thin steel plates are generally thinner in thickness. Thin steel plates themselves are lighter and thinner, and their weight is lighter, which is very convenient for handling during construction and transportation. It can save some storage and transportation space.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. api 5l psl1 grade x42 standard Heat treatment process refers to the ability to change the microstructure and properties of api 5l psl1 grade x42 standard after heat treatment, including hardenability, hardenability, temper brittleness, etc.
