Product Description:

1. Structure of Square Steel Pipe Description: 

    The square Steel pipes are used in structural projects, shelves, racks, trailers and in ornamental purpose. The framework made by square steel tubes, is used for providing support to the roof. This framework is also used as roof top ventilation baffles. With compare to round steel pipes, square steel pipes are little more efficient. The reason is that the square column is more efficient than the solid circular column.

Q:How to descaling galvanized steel pipe?
Is red rust or white rust, red rust is the base material rust, white rust is Zinc Coating Rust
Q:Seamless steel pipe and welded pipe what is the difference?
The welded pipe is made directly from the stainless steel band by machine, and it is made of round steel or perforated by Guan Pi
Q:What does "buried steel pipe" 6*2SC100 mean?
The embedded steel pipe 6*2SC100 refers to a welded steel pipe with 2 pipe thicknesses of 6mm and a diameter of 100mm. SC pipe means welded steel pipe. Embedment means pre installation (burial).
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
1.: Construction of the underground pipeline, levy more pumping, boiler hot water transportation etc..2., mechanical processing, bearing sets, processing machinery parts.
Q:What are the uses of seamless steel tubes?
A large number of pipes used for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:What's wrong with the 3PP anticorrosive steel tube?
PP and PE are similar in processability, and the 3PE coating can be used to produce 3PP coatings without the need for a special 3PP coating line. However, the difference between PP and PE materials makes the 3PP and 3PE coatings show different properties, which can be applied to different environments. The advantages of 3PP coating on some properties make it possible to play an important role in the field of 3PE coating. Therefore, many foreign pipeline projects use 3PP anticorrosive coating.
Q:What's the gate number of the precision steel pipe?
Precision steel pipe refers to the high precision steel pipe, the wall thickness and internal and external diameter can be controlled within 10 wire tolerance range
Q:What is the diameter of the steel tube DN20?
Usually the nominal diameter is nominal for cast iron pipe, steel pipe joints, concrete pipe pipe, seamless steel pipe does not use this notation (with diameter * wall thickness). With nominal diameter pipeline accessories, meaning with tube.
Q:How are steel tubes represented?
If it is seamless steel pipe, welded steel pipe, the method of expression is: nominal diameter refers to the outer diameter (diameter * wall thickness). The unit is mm. [for example, seamless steel tubes of phi 32 * 3. It means that the nominal diameter (outside diameter) is seamless steel pipe of phi 32mm and wall thickness 3mm.
Q:Where is the difference between seamless steel pipe and welded pipe
In appearance, seamless steel pipe and welded steel pipe difference in the welded pipe wall welded tendons, and seamless No.
