In today's era of economic globalization, the competition in various industries is also increasingly fierce. As a kind of metal pipe, the price of small diameter seamless square pipe is also rising gradually.
In today's era of economic globalization, the competition in various industries is also increasingly fierce. As a kind of metal pipe, the price of small diameter seamless square pipe is also rising gradually.
The price of small-diameter seamless square pipe is quite different from that of manufacturers, and the price of seamless pipe is generally much higher than that of ordinary pipe. In addition, in order to earn money, some steel mills will raise prices at different times. In addition, the price of small-diameter seamless square tubes will vary according to the use occasions.

Generally, the seamless square tube for industrial use is more expensive than the seamless square tube for water use. There are many manufacturers of seamless square tubes. How to choose? According to my experience, there are several aspects to consider when selecting a manufacturer: first, it depends on whether the factory has a good reputation and reputation; second, it depends on whether the factory can deliver goods on time and whether the quality meets the requirements.

2: Small diameter seamless square tube: performance introduction

Small diameter seamless square tube has excellent mechanical properties and durability. This kind of pipe can not only be used for manufacturing structural steel pipes, but also for manufacturing various industrial equipment and hydraulic equipment.

3: Fabrication of small diameter wireless welding method
To weld small diameter seamless square tubes, the welding starting point shall be chamfered first, and the welding point shall meet the following requirements after treatment:

(1) The axis deviation at the welding point shall be less than 3mm;
(2) The surface temperature of each welding point shall be uniform, and the temperature difference shall not exceed 20 ℃;
(3) The shape of the weld pool at the welding point shall be smooth and the depth shall be 70%~80% of the weld depth. In order to ensure the welding quality, it is usually necessary to repair the welding points. The weld shall be inspected after welding, and the inspection items include:
(1) Weld depth: the weld depth is generally 2-3 times of the weld width;
(2) Weld adhesion: the weld adhesion shall be greater than 80%~90% of the weldment thickness;
(3) Damage of welding base metal: the damage of welding base metal shall be less than 10% of the weld width.
As a kind of metal pipe, the price of small diameter seamless square pipe is also rising gradually. I hope you can consider carefully when choosing seamless square tubes and choose products with high quality and good cost performance.
