The pipe cross is a dedicated core pipe fitting for four-way diversion, merging, and pipeline distribution. Its cross structure interconnects four ports, enabling flow modes of single inlet with three outlets, three inlets with single outlet, and four-way interconnected flow. It is mainly used for multi-branch industrial pipe networks, ring pipe network connections, multi-point distribution in process pipelines, and multi-interface diversion and connection of equipment. It can replace multiple sets of tee plus elbow combination structures, greatly simplifying complex pipeline layouts and reducing weld joints and potential leak points. It is widely used in oil and gas transportation, steam pipelines, chemical fluids, water supply and drainage, fire protection pipe networks, and environmental protection water treatment systems. It can evenly distribute medium flow, stabilize pipeline pressure, avoid local eddy current material accumulation, and improve the operational stability of the entire pipeline system. It is an indispensable key pipe fitting for complex industrial pipe network layouts.

Detailed Introduction
A four-way (cross fitting) is a key branch pipe fitting in industrial piping systems. Its cross-shaped structure has four flow ports, enabling single-inlet-three-outlet, three-inlet-single-outlet, or four-way interconnection, meeting the multi-point diversion and merging needs of complex pipe networks. Compared with splicing multiple tees and elbows, a four-way can significantly simplify pipeline layout, reduce weld joints, and lower leakage risks. The product complies with domestic and international standards such as ASME B16.9, GB/T12459, and SH/T3408. The nominal diameter range is DN15-DN1200, and wall thickness grades are SCH10-SCH160 and XXS extra-heavy. It covers two major types: equal-diameter and reducing, and connection methods include butt welding, socket welding, threaded, and grooved. In terms of forming processes, we use hot pushing, hydraulic bulging, and integral forging to ensure uniform pipe walls, no defects, and a streamlined inner cavity design that reduces medium resistance. The product is widely used in petrochemical, oil and gas transportation, power plant steam systems, water treatment, and fire protection pipe networks, and is suitable for engineering projects with high requirements for pipeline reliability. We provide standard stock items and non-standard customization services, support small-batch trial samples and mixed-batch purchasing, and welcome you to contact us for selection advice and quotations.

Overview
A cross (cross fitting) is a pressure-bearing pipe branch fitting with four flow ports; its cross-shaped structure allows the pipeline to achieve merging, splitting, and distribution of media in four directions. The product is usually made of seamless steel pipe through hot pushing, hydraulic bulging, or integral forging processes, and can also be produced by forging. Crosses are mainly divided into equal-diameter crosses and reducing crosses; connection methods include butt welding, socket welding, threading, grooving, etc. Compared with using multiple combinations of tees and elbows, crosses can significantly simplify complex pipeline layouts, reduce weld joints and leakage risks, and improve the overall stability of the piping system. The product is widely used in petrochemicals, oil and gas transportation, power plants, water treatment, and fire protection systems, and is a key fitting in multi-point branch layouts of process pipelines.

FAQ
How to choose between equal-diameter crosses and reducing crosses?
If the diameters of the four ports are the same, choose an equal-diameter cross; if the main pipe diameter is larger than the branch pipe and reducing flow distribution is required, choose a reducing cross. For specific selection, it can be based on your pipeline design; you are welcome to contact us for assistance in confirmation.
What is the difference between a cross and a tee?
A cross has four flow ports and can achieve four-way flow, making it suitable for multi-line distribution and ring pipe networks; a tee has only three ports and can only achieve three-way flow splitting. When multi-line branching is required, a cross can reduce the number of pipe fittings and simplify the layout.
Can high-pressure thickened models be customized?
Yes. We support the production of SCH160, XXS, and other ultra-high-pressure thickened customized models. The specific wall thickness and material can be customized according to your operating conditions. You are welcome to provide detailed parameters for confirmation with us.
Do you support mixed batches and sample orders?
Yes. The minimum order quantity for our regular stock is as low as 1 piece, which can meet the needs of sample testing and project replacement parts. We also support mixed-batch combined orders of multiple specifications, with no mandatory minimum order threshold.
What certifications do the products have?
We can provide material certificates, inspection reports, and other documents. Please contact us to confirm the specific certification qualifications, so as to meet your project requirements.
