What is petroleum-specific tubing? How are petroleum-specific tubes manufactured?
Oil-specific tubing is a type of steel pipe used to support the well wall of oil and gas wells to ensure proper operation of the entire well during drilling and after completion. Depending on the drilling depth and geological conditions

What are the main uses of oil-specific tubes?
Different types of casing used in oil extraction: Surface Jiangsu special oil pipe protects the drilling well from shallow water and gas reservoirs, supports wellhead equipment and keeps the weight of other layers of casing. Technical Jiangsu oil special tubing separates the pressure in different layers so that the drilling fluid quota can flow properly and protects the production casing.
One minute to introduce the principle of Jiangyin gas seal buckle seal
The sealing principle of Jiangyin gas seal buckle is that the gas ring needs to be closely matched with its own elasticity and cylinder inner wall. This is the premise that in the compression and working stroke, the high-pressure gas flow in the cylinder through the gap between the piston and the cylinder into the side of the ring groove and the gap between the teeth, under the action of gas pressure, press the ring on the cylinder inner wall and the ring groove to improve the sealing performance.
Uses of seamless steel pipes of various materials
GB/T8162-1999 (seamless steel pipe for structure). Mainly used for general structure and mechanical structure. Its representative materials (grades): carbon steel 20, 45 steel; alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.
Does the precision seamless steel pipe have a strong elasticity
Seamless steel pipe is a kind of steel with high elasticity, which is used in most of the applications, especially in large buildings with high elasticity requirements. Why is the elasticity of seamless steel pipe so good? The reason is that a lot of elements are added inside, let's take a look at it together:

What is the difference between welded steel pipe and seamless steel pipe
Welded pipe, also known as welded steel pipe, is basically a steel pipe made of steel sheets or strips that have been rolled into shape and then welded. Since the 1930s, with the rapid development of you quality strip steel continuous rolling production and welding and inspection technology advances, the quality of the weld seam continues to improve, the increasing variety of welded steel pipe specifications, and in more and more areas instead of seamless steel pipe. Welded steel pipe according to the form of welded seam is divided into straight seam welded pipe and spiral welded pipe.
