A420 WPL6 Tee

A420 WPL6 tee is a pipe fitting with three ports, mainly used to divide a pipe into two branches or merge two branches into one pipe. Common ones are equal diameter tees and reducing tees. In the layout of the pipeline system, the structure of the tee can flexibly change the flow direction of the fluid to achieve the function of branching or merging.

A420 WPL6 tee is a pipe fitting with three ports, mainly used to divide a pipe into two branches or merge two branches into one pipe. Common ones are equal diameter tees and reducing tees. In the layout of the pipeline system, the structure of the tee can flexibly change the flow direction of the fluid to achieve the function of branching or merging.
A420 is a standard developed by the American Society for Testing and Materials (ASTM), mainly covering forged carbon steel and alloy steel pipe fittings for low temperature. This standard ensures the performance requirements of pipe fittings in low temperature environments. For example, in the cryogenic storage and transportation system of the petrochemical industry, pipe fittings produced according to the A420 standard can withstand low temperatures without brittle fracture.
WPL6 is a material grade in the A420 standard. It is a carbon steel with good forgeability and weldability. During the manufacturing process, the tee made of WPL6 material can form a complex tee shape through the forging process, and in the subsequent installation process, it can be easily welded to other pipe fittings or pipes.

Application areas

Petrochemical industry: In the process of oil refining, natural gas processing and chemical product production, there are a large number of pipeline systems for transporting various fluid media, such as crude oil, natural gas, various chemical raw materials and products, etc. A420 WPL6 tee can be used at the branches and junctions of these pipeline systems, such as at the branch point of the crude oil pipeline, for distributing crude oil to different processing units; or in the natural gas processing plant, for converging natural gas from different sources into a main pipeline.
Cryogenic engineering: Due to the requirements of the A420 standard for cryogenic performance, the WPL6 tee is suitable for the field of cryogenic engineering. For example, in the storage and transportation facilities of liquefied natural gas (LNG), LNG is at an extremely low temperature (about -162°C). In the relevant pipeline system, the A420 WPL6 tee can work reliably in a low temperature environment to ensure the safe transportation and storage of LNG.
General industrial pipeline system: In some ordinary industrial enterprises, such as power plants, paper mills, food processing plants, etc., there are also a large number of pipelines for transporting steam, water, raw materials and products. A420 WPL6 tee can be used to build a reasonable pipeline network according to specific pipeline layout requirements to achieve fluid distribution and collection.
