When comparing PVC, UPVC, CPVC, PP, PE, PB, and PVDF plastic pipes, it's essential to consider their individual properties and distinctions. Each type of plastic pipe offers unique characteristics that cater to specific applications and operational requirements. PVC, UPVC, CPVC, PP, PE, PB, and PVDF pipes differ in...

Main stages of pipe cleaning 1.1 Cleaning of prefabricated pipe sections As for the cleaning of pipes before module assembly, all carbon steel pipes should be pickled and phosphated after prefabrication in the workshop to remove impurities, welding slags and rust spots on the pipes. After welding, all stainless steel pipes...

The reasons for the failure of rupture of boiler desuperheating water pipes The reducers of the desuperheating water pipe of a thermal power boiler were ruptured. Through sampling of the reducers, macroscopic inspection, chemical composition analysis, hardness testing, and energy spectrum analysis were carried out...

Introduction As the most complex industrial system, the thermal power boiler system has many pipes or components that are subject to high temperatures and pressures, and the types and forms of component failure are also diverse. The most common among them are failures of the four tubes of the boiler such as water...

A seamless steel pipe is a type of pipe that is manufactured without any seams. It is made from a solid round steel billet, which is heated and pushed or pulled over a form until the steel takes on the shape of a hollow tube. This process, known as hot rolling, ensures that the final product has a smooth and uniform surface....

Abstract: The causes of surface cracks in stainless steel seamless pipes made from 0Cr18Ni9 were analyzed and improvement measures were proposed. After analysis, it is believed that inclusions gotten into the round steel during smelting or pouring caused cracks in the perforated tube blank. The cracks further expanded...

Wear-resistant seamless steel pipes have become an indispensable component in various industries due to their exceptional durability and reliability. These pipes are specifically designed to withstand high levels of wear and tear, making them ideal for applications that involve the transportation of abrasive materials...

At present, there are many types of wear-resistant pipes in China, mainly cast steel pipes, cast iron pipes, welded pipes using plate coil welding, bimetal composite pipes, surfacing composite pipes, ceramic composite pipes and other double-layer composite pipes.   Wear-resistant pipelines are widely used for transporting...
