A333 and A335 are two different grades of alloy steel pipe elbows. Each grade has its own unique characteristics, applications, and uses. A333 is a low-temperature steel alloy, meaning it has a higher degree of ductility and is better suited for lower temperature applications. It is commonly used in the production of elbows for low-temperature…
What harm does h2s do? How should pipe fittings be treated to resist damage from h2s? H2S is a colorless, flammable gas that is produced by the breakdown of organic materials and is a by-product of the industrial production of many materials. It is also a naturally occurring gas, found in areas like sewers, landfills,…
A slip on flange and a weld neck flange are two of the most common types of flanges used in piping systems. While they may seem similar, they actually have many differences that make them better suited for different tasks. 1. Connecting Method: The primary difference between a slip on flange and a weld neck…
Butt welding pipe fitting is a type of pipe fitting used for connecting two pipes of different sizes, materials, or configurations. It is one of the most common types of pipe fitting and can be used for all types of applications, including residential, commercial, and industrial. Butt welding is a type of welding process…

Summary of the difference between seamless steel pipe and welded steel pipe API 5L/ASTM seamless steel pipe and ERW welded steel pipe have the following differences: 1. Appearance differences Seamless steel pipe is made of steel billet. Outer surface defects in the steel billet cannot be eliminated by the hot rolling process and are only…
Long-necked butt welding flanges are common dedicated connections used in industries such as energy, petroleum and petrochemicals. They are commonly found in complex piping systems that serve multi-storey buildings and refineries. But why are they considered the perfect pressure vessel connection for these piping systems? Here are some of the reasons: Example of a long…
