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.

Butt Weld Cap We are manufacturer of butt weld cap and supplies all schedules in kinds of materials such as carbon steel, stainless steel, alloy steel. Zizi produces pipe caps in ASME, DIN, JIS and other required standards. Pipe cap is one of the common used pipe fittings for stoping fluid by covering at the pipe end. It is available in butt weld type, socket weld type and threaded type, and buttweld cap is more popular in view of the good performance, stable connection and large dimension selection range.
