BUTTWELD TEEEQUAL TEEAn equal tee, otherwise called straight tee, is a buttweld fitting used to branch a pipeline, or any other pipework, at 90 degrees. Equal tee asme b36.19A pipe tee is defined “equal” when the bore size at the run and branch sides have the same diameter. An equal tee is, therefor

Heat treatment is used to avoid or alleviate the detrimental effects of high temperatures, which are unavoidable during the welding process. The heat treatment required and the recommended temperatures and holding times vary among metals. They are specified in ASME B31.3, Table 331.1.1, Requirements

Pipeline MaterialMild steel pipes and casing (externally flush) were commonly used since 1940s. They suffer from many drawbacks. Some of them are listed below:1.Very heavy in large sizes (above 5″ in diameter) and liable to hurt workers.2.Must be on floor and prone to get damaged by both floor heavi

When installing a firewater system, consideration should be given to the materials of construction and to the overall layout.Materials of constructionSteel pipe should be used aboveground for firewater lines. Underground piping systems can be constructed of steel, cement-lined steel, or high-density

Steel pipe is generally used aboveground for firewater lines. Underground piping systems can be constructed of steel, cement-lined steel, or high-density polyethylene (HDPE). Concrete is sometimes used but is seldom economical except in large diameters. HDPE does not corrode, resists accumulation of

Welded pipes, are also called welded steel pipes, are made by welding steel. Simple production process, high production efficiency and variety of specification, the welded steel pipes replace gradually the seamless steel pipes in more and more industries.We provide different types of welded steel pi
