In the processing of the precision parts, there are always some unsatisfactory places. Although we have the best processing machine, the best processing master and after processing everything is so perfect, after winning the machine into the quality control room or the next process,

In common condition, we can be divided into two kinds of clod drawn and hot rolled according to seamless steel pipe production process.Today I will introduce difference between hot rolled steel tube and cold rolled steel tube from following two parts: Applications and Product process.

Changzhou Chuangcheng preicision seamless steel tube is used for mechanical structure,hydraulic equipment’s size with high preicision and good surface finishment.Why manufacturing mechanical structure industry and hydraulic equipment industry need cold rolled seamless steel tube?

Seamless steel pipe is the steel with hollow structure and seamless surface. It can be widely used in oil and gas transportation, mechanical components and some ring parts. There are a lot of materials for seamless steel pipes. So different material and product technology cause different mechanical

Recently Christmas is very popular in China. Do you know why, for many Non-christian believers this is also a shipping day such as Double Eleven. So the most reason is from purchaser promoting. Many shopping malls give Christmas rush, big discount which really attract people's eyes.

All of us must know the standards of seamless steel tube, such as DIN2391, En10305-1 and GB3639. We also know that they have different names, but the details are similar. Din 2391 is the standard from German, En10305-1 is of Britain, and GB3639 is of China.

Seamless steel pipes and tubes are standard commodities which must be subject to special standard. The ASTM A179 is the standard for seamless cold-drawn low-carbon steel heat exchange and condenser tubers.They are widely used in chemical engineering, petroleum, steel and automatic mobile and many other industrial equipment.
