LSAW Pipe vs SSAW Pipe
1. Advantages of LSAW steel pipe: (1) The tube expansion process used in LSAW steel pipe manufacturing results in residual stress close to zero and eliminates the ‘Bauschinger’ effect. However, in the case of SSAW steel pipe, the manufacturing process results in molding stress and the...Read more -
What material is oil casing manufacturing
Oil casing is a large-diameter steel pipe that plays a role in fixing the walls or wellbore of oil and natural gas wells. Usage: Petroleum casing is inserted into the wellbore and fixed with cement to prevent the wellbore from separating rock layers and wellbore collapse, and to ensure the circul...Read more -
Multi-wire submerged arc welding technology for LSAW pipes
As welding is the main process in the production of straight seam steel pipes, particularly for high-quality oil and gas pipes, it is necessary to ensure high quality while also improving welding efficiency. The length of the weld for straight seam steel pipes is typically quite long, usually aro...Read more -
Selection of steel pipe anti-corrosive coating
There are many types of anti-corrosion coatings, and their properties and uses are different. The correct selection is crucial to the anti-corrosion effect and service life of the coating. When choosing: 1. The nature of the surface material of the coated object For example, iron red and red lead...Read more -
Welded steel pipe for low pressure fluid transportation
Welded steel pipe for low-pressure fluid transportation (GB/T3092-1993) is also called a general welded pipe, commonly known as clarinet. It is a welded steel pipe for conveying water, gas, air, oil and heating steam, and other generally lower pressure fluids and other purposes. The wall thicknes...Read more -
High Steel Grade Line Pipe
The production of high-grade steel line pipe relies on a micro-alloying heating process. The heat treatment process for high-grade steel line pipe is crucial. The scope of welded pipe applications for pipelines has gradually expanded, particularly in the large-diameter group spacing range where w...Read more
