Stainless steel pipe
is a hollow strip of round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also used as furniture and kitchenware.
Stainless steel pipes
are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetallic composite pipes, coatings and coating pipes for saving precious metals and meeting special requirements. . Stainless steel tubes are available in a wide variety of applications, with different technical requirements and different production methods. The outer diameter of the currently produced steel pipe ranges from 0.1 to 4500 mm and the wall thickness ranges from 0.01 to 250 mm. In order to distinguish the characteristics, the steel pipes are usually classified as follows.
1.Every cartons loaded with good shoring and strengthening in container well to make it safe arrive at destination port.
2.Take container loading pictures and seal the container.
3.Transportation speed is quick. And keep customer eachstep informed.
