The ASTM A420 WPL6 pipe fittings are designed for low temperature service,when we choose the A420 WPL6 fittings,it could work in the -50 degree F at lowest.Low-temperature carbon steels have been developed chiefly for use in low-temperature equipment and especially for welded pressure vessels.
The ASTM A420 WPL6 steel pipe fittings are butt welding joint ends,it will be used to connected with the steel pipes,steel fittings or flanges which material is also produced for low temperature service,for example the ASTM A333 Grade 6 steel pipes,or ASTM A350 LF2 material forged flanges.
When we choose the WPL6 materials,we should check the impact test value in -46 ℃,it is an important character for low temperature service material.After the welder finish the welding of WPL6 pipe fittings to other piping products,the post weld heat treatment is very critical job.
A very important thing for A420 WPL6 pipe fittings is the stockage,the marking on the fittings should be kept clearly.WPL6 pipe fittings have a same look with common carbon steel pipe fittings,so traceable work is very important for them.(What is ASTM A420 WPL6 pipe fittings?)
