Our steel low-temperature pipe fittings series includes ASTM A420 WPL6 series pipe fittings to meet the needs of various low-temperature applications.
1、 Basic characteristics of ASTM A420 WPL6 pipe fittings
ASTM A420 WPL6 fittings are fittings used in low-carbon steel pipeline systems, and their low temperature resistance can meet the requirements for use in low temperature environments ranging from -45 ° C to -195 ° C. In addition to excellent low-temperature performance, ASTM A420 WPL6 pipe fittings also have the following characteristics:
1. Good corrosion resistance: The chemical composition of ASTM A420 WPL6 pipe material determines its excellent corrosion resistance. In strong acid and alkali environments, it can also maintain stability without material corrosion and deformation.
2. High strength and good plasticity: ASTM A420 WPL6 pipe fittings have excellent strength and plasticity, can effectively withstand pressure, ensure the stability of the pipeline, and are easy to machine into various shapes of pipe fittings.
3. Excellent welding performance: ASTM A420 WPL6 pipe material is suitable for various welding methods, including manual arc welding, automatic submerged arc welding, argon arc welding, etc. No special treatment is required during welding, and welding can be carried out directly.
4. Environmental Protection and Health: ASTM A420 WPL6 pipe fittings meet environmental and health standards and will not have harmful effects on the environment and human health. And the materials are lighter, reducing transportation costs.
2、 The main applications of ASTM A420 WPL6 pipe fittings
ASTM A420 WPL6 pipe fittings are widely used in various liquid petroleum and natural gas engineering, such as refining, chemical engineering, natural gas liquefaction, ocean engineering, etc. It can maintain stability in extremely low temperature environments, prevent system leakage, and protect system safety and stability. Mainly including the following areas:
1. Low temperature compressor system: When transporting liquid natural gas, a more reliable and corrosion-resistant pipe fitting system is required due to the extremely low temperature of liquid natural gas. ASTM A420 WPL6 fittings can meet the requirements of this environment and are also suitable for low-temperature compressor systems in fields such as petroleum and chemical engineering.
2. Liquefied gas transportation: During the storage and transportation of liquefied gas, stricter safety measures are required. ASTM A420 WPL6 pipe fittings are widely used in this field, meeting national standards and transportation regulations, ensuring the safety of liquefied gas storage and transportation.
