ASTM/ASME SA420 WPL3 WPL4 WPL5 WPL6 Low temp Carbon Steel Fittings
ASTM A420 WPL6 Pipe Fittings are one kind of butt welding pipe fittings,they are commonly produced from the steel pipes of ASTM A333 Grade 6. This material should be arranged the charpy V impact test in temperature of -46℃, to make sure it can work in a lower temperature service, for example in cold weather, winter or deep-sea water offshore projects.
ASTM A420 WPL6 Buttweld Pipe Fittings shall undergo in the radiographic examination, hydrostatic testing etc. in order to improve the quality of the product. This pipe fitting is packed in a wooden box or case in order to avoid damage. This is used in many applications like petroleum, machinery, etc and it is available in accurate dimension, durability, and other features.
