9 matters need attention for pipe cutting operation​ 1. The dust removal device of cutting machine should be in good condition before cutting.   2. The spindle speed should be carried out after stopping running. When changing speed, gears should mesh to fully. When the machine tool is abnormal, immediately stop and...

Due to gas has increasing influence on heat exchange tube, heat exchange tube heat protection has become an important work of power plants. Heat exchange plate engineering anti-corrosion and its coating are keys to the whole process. Heat exchange tube heat transfer piece generally requires no water seepage, corrosion,...

The coating process of double fusion bonded epoxy powder coating is simple. This process can be conducted on the basis of the fine-tuning on the original single fusion bonded epoxy powder coating equipment, namely dividing spray gun into three groups. The first group sprays the inner powder; the second group sprays outer...

Carbon steel pipe is made from ingot or solid round steel after perforation, then though hot rolling, cold rolling or cold calling. Carbon steel pipe plays an important role in China's steel industry. Classification Carbon steel pipe can be divided into two categories: hot and cold rolled (pull) steel. Hot-rolled carbon...

Steel pipe generally can be divided into two categories: one is welded steel pipe, the other is seamless steel pipe.  Welded steel pipe, also known as welded pipe, it is made of steel sheet or strip that experience crimp forming welding. The production technology of welded steel pipe is simple, with high production...

Lineation, Cutting stock and Groove  1. Steel lineation is base on construction drawings, and considers the factors, such as cutting loss, welding shrinkage and so on. After lining, to label steel section, section number, flow direction, the horizontal and vertical center line, groove angle and cutting line with steel...

The OCTG pipe refers to the seamless tube used in oil wells. Its manufacturing methods are the same as seamless tube, domestic industries use steel to produce, such as DZ (geology) 35 ~ DZ55, etc. There is a thread on both ends of the steel tube, for combining with joint. In order to ensure the joint sealing, this kind...
