A four-way pipe usually refers to a pipe fitting used to connect four pipes in a fluid transport pipeline system. 

Classification

Classified by material: mainly divided into cast iron, carbon steel, stainless steel, copper, plastic and other materials, among which plastic materials include UPVC, CPVC, PPH, PVDF, FRPP and so on. Four way fittings made of different materials are suitable for different application scenarios, such as cast iron fittings suitable for high-temperature situations in chemical transportation pipelines.

Classified by connection method: mainly divided into flange connection, threaded connection, hot melt connection, electric welding connection, and bayonet connection. Flanged and threaded connections are commonly used in ventilation and environmental protection duct systems in public and commercial buildings because they are detachable and easier to maintain.

Classified by connection angle: mainly including equal diameter four-way fittings, reduced diameter four-way fittings, equal platform four-way fittings, etc. The connecting port diameter of equal diameter four-way fittings is the same, which can be used for transporting fluids in the same direction; Reducing four-way fittings and equal platform four-way fittings are suitable for situations where fluids need to be transported in different directions.

Classified by process: There are mainly three processes: forging, casting, and bending pipe connection. Forged four-way fittings are suitable for high-pressure and high-temperature fluid transportation pipeline systems; Casting four-way fittings is usually used for situations with ordinary pressure levels and lower temperatures; The four-way fittings connected by bent pipes are suitable for use at corners.

Characteristic

Convenient connection: It can quickly and easily connect four pipes together, reducing the time and workload of pipeline installation.

Easy to operate: Regardless of the connection method, the operation process is relatively simple and does not require complex techniques and tools, reducing the difficulty of construction.

Low fluid resistance: The design is reasonable, the internal flow channel is smooth, and the resistance of the fluid passing through the four-way pipe is small, which can ensure the smooth flow of the fluid and reduce energy loss.

Beautiful appearance: The appearance is usually neat and simple, suitable for various pipeline systems, and can coordinate with the surrounding environment.

Quick disassembly and assembly: For four-way fittings that use detachable connection methods such as flange connections and threaded connections, they can be easily disassembled and installed when repairing or replacing pipelines.

Application

Chemical industry: used for transporting various corrosive or non corrosive fluids such as chemical raw materials, acid-base solutions, organic solvents, etc.

Oil and gas industry: used to connect pipeline systems in the extraction, transportation, and processing of oil and gas, achieving the diversion, convergence, and transportation of oil and gas.

Paper industry: pipeline systems used for pulp transportation, white water recovery, steam and water supply in the papermaking process.

Food and beverage industry: suitable for pipeline connections in the production process of food and beverage, including raw material transportation, finished product filling, cleaning and disinfection.

Pharmaceutical industry: used in pharmaceutical production to transport various drugs, distilled water, compressed air, etc., to meet the hygiene and quality requirements of drug production.

Construction industry: used for connecting and branching pipelines such as water supply and drainage systems, heating systems, air conditioning systems, etc. inside buildings.
