Socket Welding Fitting ASTM A105 Carbon Steel Coupling B16.11 Oil Gas
What Is ASTM A105 Carbon Steel Coupling?
A coupling can be described as a small piece of pipe or tubing with a socket at one or both ends. It helps to connect pipes and tubes.ASTM A105 coupling covers seamless carbon steel forged tubes used in high temperature applications in pressure systems. It is also very durable because it is made of high quality carbon steel.
