Stainless steel threaded cap fitting is screwed to the end of pipeline, it has same function as plugs. The difference is female / male thread and weight & dimensions. It is similar to the blind plate in form, but the blind plate can be moved and removed, while the pipe cap cannot be removed.
Forged threaded end caps are generally conform to material of Stainless Steel and dimensions of ASME / ANSI B16.11. They are used to protect the pipe ends in different shapes. Compare with threaded elbow, threaded tee and threaded coupling, it is not used too much cut to its function.
The use of Stainless steel thread cap is common in many industries such as oil and gas industries, chemical industries and water supply lines.
