Brief Introduction of ASTM A860 Butt Weld Cap
ASTM A860 is the standard specification for wrought high-strength ferritic steel butt-welding. There are several grades such as the grade WHPY 42, 46, 52, 56, 60, 65, 70 corresponding to pipe standard of API 5L X42 to X70, which is used for oil and gas transmissions.
ASTM A860 butt weld cap is a type of pipe fitting that is used to close or seal the end of a pipe or tube in a butt welding joint. What is more, butt welding is a common technique in which two pieces of metal are joined together by melting their ends and fusing them together.
Pipe fittings like caps shall be furnished in accordance with the dimensions of ASME B16. 9 (for sizes NPS 14 and smaller) or MSS SP 75(for sizes NPS 16 through NPS 48).

Purpose of Butt Weld Cap
The main purpose of using ASTM A860 butt weld caps is waterproofing the connections. And they are also used to close the the ends of hydraulic or pneumatic pipes and tubes. They are widely applied in the plumbing apparatus of domestic, commercial and industrial water supply lines, machinery and processing equipment etc.
