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.

What is the difference between welded steel pipe and seamless steel pipe

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.
