A stainless steel butt weld cap is a type of pipe fitting that covers the end of a pipe. Since it can have female threads, it can screw on to the male end of the pipe. It can also be welded on to close the end of the pipe. On a weld, if it is a temporary close, or the contractor wants to add to the piping system in the future, he or she should allow additional pipe before closing so the pipe cap can be cut off and the pipe system extended as needed. This way you will not have less pipe than you need and the new fitting can be attached correctly.
A Stainless Steel Butt Weld Cap is used to seal the end of a pipe or a particular butt weld fitting branch or orifice. Typically butt weld pipe caps are used at the end of a piping system or if maintenance is required the pipe cap can blind or isolate the rest of the system to keep it running while maintenance or repairs are performed.

Steel bars are one of the core components of any manufacturing
industry or for that matter any industry that relies on machineries.
Thanks to its versatile applications, steel bars find itself in the
epicenter of most of engineering industries, be it automotive, textile,
fabrication, construction, cement, ship building, paper and pulp,
defence, heavy earth moving equipments or aerospace.
The overwhelming popularity of steel bars is owed to the fact that
it is possible to be produced in varying types, shapes, sizes, and
grades of bars to cater the exact technical requirements. Steel
bars generally have the shapes such as flat, round, hexagonal,
square and channel and on most of the occasions, it is the shape
of the bar that defines its application area
