Buttweld Pipe Cap, SS Butt weld Cap, ANSI B16.9 Pipe Caps
Butt weld fittings get their name from the method for which they attached to a piping system. Each end of a butt weld Caps fitting is beveled, and it is attached by butting the fitting up to the adjoining pipe and welding along the bevel. This connection is both stronger and smoother than threaded or socket weld connections, making butt weld fittings the preferred product for critical applications.
Caps are butt weld fittings used to terminate the flow, welding to the end of a butt weld fitting or pipe.
The steel pipe cap is welded at the end of pipes or installed on the external thread and is used to block the pipe. There are many kinds of convex pipe caps such as hemispherical pipe cap, oval pipe cap, disc-shaped pipe cap and spherical cap. Bending, extruding, pushing, molding and machining manufacturing methods are used to produce it.
Steel pipe cap acts as a protective piece and is designed to protect ends of different shapes. Its main purpose is to make pipe connections waterproof. The steel pipe cap is widely used in the plumbing lines of domestic, commercial and industrial water supply, machinery and processing equipment. Besides, pipe cap is fitted on water pump lines with the sole purpose of removing air blocks.

Introduction to Hot Forming – Manufacturing of Butt Welded CAPS
The manufacturing process of caps starts from steel plates that are cut and shaped with a cold forming procedure:
Pipe fittings are used in plumbing systems to connect straight sections of pipe or tubes, to accommodate different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow. These fittings are used in plumbing systems to control the transfer of water, gas or liquid waste within pipes or plumbing systems in domestic or commercial environments. Fittings (especially uncommon types) require money, time, materials and tools to install and are an important part of plumbing and plumbing systems. Common pipe fittings mainly include: flange, elbows, couplings, unions, spools, reducers, bushings, tees, diverter tees, crosses, caps, plugs, barbs and valves. Although valves are technically fittings, they are usually discussed separately.
Pipe fitting bodies are usually made of the same base material as the pipe or tubing they are connected to: copper, steel, PVC, CPVC or ABS. Any material permitted by plumbing, health or building codes (as applicable) may be used, but it must be compatible with the other materials in the system, the fluid being conveyed, and the temperature and pressure inside (and outside) the system. Brass or bronze fittings over copper Common in plumbing and plumbing systems. Fire resistance, shock resistance, mechanical strength, anti-theft and other factors also affect the choice of material for pipe fittings.

Cross fittings allow for the branching of pipes, enabling the distribution of water or other fluids to various fixtures or areas. They are commonly used in water supply systems, irrigation systems, and heating systems.
Concentric reducers are used where the pipework is vertically installed and at the discharge side of pumps. Eccentric reducers are more often used when the pipework lays on a pipe rack. Because of the flat side, aligning and securely mounting the pipes to the rack is easier.
