Threaded Cross
The threaded four-way is a four-directional flow-dividing pipe fitting that requires no welding and features quick disassembly and assembly. It relies on precision internal thread screwing for sealing, realizing the functions of four-way pipeline flow division, merging, and medium distribution, and is specially designed for small-diameter industrial pipe networks. It requires no hot work welding and no groove processing, and is flexible and convenient to install and disassemble, greatly reducing on-site construction difficulty, and is suitable for pipeline scenarios where hot work is not allowed, space is narrow, and frequent maintenance is required. It is mainly used for instrument sampling pipelines, steam tracing pipelines, small gas transmission pipes, hydraulic and pneumatic pipelines, water supply and drainage pipe networks, HVAC circulation systems, and low-pressure chemical branch pipelines. It can stably transport water, steam, gas, compressed air, and ordinary corrosive fluid media, effectively distribute pipeline flow and pressure, streamline pipeline layout, and reduce the number of joints. It is suitable for medium-low pressure to medium-high

Overview
A threaded cross is a forged female-threaded connection-type cross fitting that screws onto pipes through the internal threads of its four ports to achieve four-way flow splitting or merging. Its design eliminates welding operations, and installation and disassembly only require tightening with tools, making it particularly suitable for pipeline systems that require frequent maintenance, prohibit hot work, or have limited space. The product complies with ASME B16.11, GB/T14383, and BS3799 standards, with pressure ratings covering 2000LB to 6000LB, nominal diameters ranging from DN6 to DN100, and compatibility with multiple thread types. Integral die forging ensures material density and mechanical strength, making it suitable for multiple media such as water, steam, gas, and compressed air.
Key Features
The core advantage of the threaded cross lies in welding-free installation, requiring no hot work, allowing repeated disassembly and assembly, and greatly reducing construction difficulty and safety hazards. The integral die forging process makes the product structure dense, free of sand holes and porosity, and superior in pressure resistance to cast parts. Precisely machined threads ensure reliable sealing and reduce leakage risk. The product is compact in size, suitable for dense pipeline layouts, and saves space. We provide a full range of specifications and multiple thread types, support non-standard customization, and have sufficient stock for rapid delivery.

FAQ
What working conditions are threaded crosses suitable for?
Threaded cross is suitable for small-diameter pipelines from DN6 to DN100, with a pressure rating of up to 6000LB, and is suitable for static or low-vibration working conditions from medium-low pressure to medium-high pressure. It is commonly used in instrument tubing, heat tracing systems, gas transmission, water supply and drainage, etc., and is especially suitable for installation environments where hot work is prohibited or space is limited.
What is the difference between a threaded cross and a socket weld cross?
Threaded cross connects by threads, requires no welding, and can be repeatedly disassembled and assembled, making it suitable for occasions with frequent maintenance; socket weld cross needs to be fixed by fillet welding, and has stronger sealing performance and pressure resistance, but it is not detachable. Which one to choose depends on the specific working conditions and installation requirements.
How to choose the thread standard?
American equipment usually uses NPT threads, British or municipal pipelines commonly use BSPT or BSPP, and other standards such as RC can also be provided. We support mixed thread customization and can select the appropriate thread type according to your pipeline standard.
Can threaded cross be used in explosion-proof areas?
Yes. Threaded cross uses threaded connection, requires no welding, and involves no open flame operations, making it very suitable for explosion-proof workshops, confined spaces, and other areas where hot work is prohibited.
Can it be used under high-pressure working conditions?
Yes. We offer thickened products in 3000LB and 6000LB pressure ratings, which can meet the requirements of medium and high pressure working conditions. For specific model selection, please provide the working pressure and medium, and we will assist in confirming.
