During the welding process of thin-walled stainless steel pipes, issues such as burn-through, deformation, and susceptibility to rusting of the weld seam often arise due to factors related to welding equipment, welding parameters, and operational details. Below, we'll delve into the welding technology for thin-walled...

Seamless steel pipes are elongated steel materials with a hollow cross-section and no seams around the perimeter. They find extensive application in various industries, primarily for fluid transportation purposes, including conveying oil, natural gas, gas, water, and certain solid materials. Compared to solid steel materials...

To ensure that the quality of high-frequency welded pipe products meets technical standards and customer needs during the production process, it is essential to analyze the factors affecting product quality in steel pipe production. By analyzing the statistics of non-conforming products from a certain Φ76mm high-frequency...

There are five connection structures between the steel tube and the tube plate in heat exchangers. The connection of the steel tube to the tube plate is a crucial part of shell-and-tube heat exchanger design. It involves significant processing work and requires every connection point to ensure media leakage prevention...

PP-R pipes, also known as polypropylene random copolymer pipes or PPR pipes, boast advantages such as energy efficiency, environmental friendliness, lightweight yet high strength, corrosion resistance, smooth internal surface preventing scaling, easy installation and maintenance, and long service life. They find wide applications...

Galvanized steel pipes are commonly used in our daily lives, produced by treating steel strips with galvanization technology. To enhance corrosion resistance and prolong the lifespan of the pipes, a layer of zinc coating is added to the surface through galvanization, effectively isolating the steel from corrosive media....

Boiler tube bursts occur when tubes in the heat exchange surface of a boiler burst due to factors like overheating, erosion, and corrosion, resulting in high-temperature water leakage and disrupting normal boiler operation. Research suggests several main causes for these bursts. Wear This includes fly ash erosion, slagging...

1. Introduction With the development of oil and gas exploration and development, oil and gas mining faces increasingly harsh environments. These environments are places with high temperature and pressure, high chloride ion content, high salinity and high water content, high carbon dioxide content, and high hydrogen...

Boiler tube burst refers to the phenomenon where the water-cooled wall tubes, convective tubes, and economizer tubes in the heat exchange surface of a boiler burst due to various factors such as overheating, erosion, and corrosion during operation, leading to high-temperature boiler water leakage and rendering the boiler...

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...

Lap Joint Flanges Lap joint flanges are a type of flange used in piping systems to connect two pipes or pipe fittings. They consist of a flat, circular plate with a raised inner lip that fits over the end of the pipe. The flange is then secured to the pipe by bolting it together with another lap joint flange. One of the main advantages of lap joint flanges is their ability to rotate freely around the pipe. This allows for easy alignment during installation and reduces stress on the piping system. Additionally, lap joint flanges are relatively inexpensive compared to other types of flanges, making them a popular choice in many industries. Another benefit of lap joint flanges is their versatility. They can be used with pipes made from different materials, such as steel, stainless steel, or plastic. This makes them suitable for a wide range of applications, from water and gas distribution systems to chemical processing plants....

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...
