Advantage of ms pipe and DSAW Steel Pipe

(1)Advantage of ms pip

Ms pipe annealing organization ferrite and pearlite, lower its strength and hardness, ductility and toughness. Therefore, it can be a good cold formability curling, bending, stamping and other methods of cold forming. This steel has a good weldability. Low carbon content of ms pipe is very low hardness and poor machinability, quenching can improve machinability. However, for the manufacture of steel pipes, because it is very durable. Different types of steel are used in many industries, because it can withstand the pressure, the pressure rarely increases to break or bend. These can be used for the underwater pipe, as it is resistant to corrosion. Quite thick steel tensile strength and durability can be maintained intact under great pressure. These steel pipes are used in various industries, because it can be produced according to customer requirements.

Advantage of ms pipe:

1, can obtain a high hardness (HRC60-65), and better wear resistance after heat treatment.

2, moderate hardness of the annealed condition, has good machinability.

3, the raw material, low in production cost.

(2)Advantage of DSAW Steel Pipe

In accordance with the cross-section and shape,LSAW steel pipe is divided into the sub-shaped tubes and tube. Perimeter commensurate area of a circle is the largest, so you can transport more liquid. Therefore, the vast majority of DSAW steel pipe, each spiral are tightly controlled after the hydrostatic test, the test pressure and the time by the steel pipe pressure microcomputer monitoring device, the test parameters automatically printed record.

The specific requirements of spiral strip is to forward the weldability of structural steel pipe,reducing the sulfur content in the steel are beneficial to improve the toughness of the steel pipe and crack arrest. This can also reduce the sulfide inclusions, transfers, advance steel crack resistance. Phosphorus content in hot-rolled strip is as low as possible, because the phosphorus on the strip, toughness and weldability harm, thus reducing the phosphorus content can be directly forward weldability may be appropriate to add additional titanium, vanadium, niobium content.
