跳到内容 Yuhuan Hongqian Machinery Co., Ltd. specializes in custom-made galvanized pipe connectors, 1/4 compression fittings, fitting bulkheads, and bulkhead plumbing fittings for global customers across industrial, automotive, hydraulic, and plumbing sectors.
Unlike standard stock suppliers, we focus on precision-engineered OEM & ODM fittings tailored to your specifications. Our galvanized fittings are designed and produced to meet international quality standards, ensuring exceptional performance and long service life in demanding environments.
Our galvanized pipe connectors and Galvanised Steel pipe Fittings are well designed and manufactured to provide a cost-effective solution that is reliable and boasts a long lifespan, exceeding 50 years. These fittings demonstrate resilience against temperatures ranging from -20°C to 300°C and high working pressures, reaching up to 2500 kPa, that are coated in zinc to protect against rust, corrosion, and mineral buildup. Our products include bulkhead fittings , automobile pipe fittings, hext nuts , tees, elbows, flanges, sockets, and caps.
Galvanized elbows are designed to change the direction of flow in a piping system.
They are available in 45° and 90° angles, allowing for smooth directional transitions.
Regular elbows connect directly to pipes.
Street elbows connect to another fitting (not the pipe) — perfect for tight installation spaces.
Custom-made elbows from Yuhuan Hongqian can be designed with BSP, NPT, or metric threads to match your system perfectly.
Galvanized couplings connect two straight lengths of pipe.
They ensure leak-free connections and can be manufactured in full or half-coupling styles.
Custom couplings are available for high-pressure or special-dimension applications.
Pipe caps are used to close the end of a galvanized pipe, protecting it from dust, dirt, and moisture.
These are often used during pressure testing or to seal unused pipe sections.
At Hongqian, we provide custom caps in various thread sizes and shapes.
Core plugs (also called square head plugs) feature threaded male ends and are inserted into a female-threaded pipe.
They provide a secure closure and can be easily tightened with a wrench.
Our precision-machined galvanized plugs ensure tight sealing under high pressure.
Tee fittings are used to combine or split the flow of fluids.
They are available in equal or reducing designs to connect pipes of the same or different diameters.
Custom tee fittings can also be designed with side ports for instrumentation or control valves.
Galvanized unions connect two pipes but can be easily disconnected for maintenance or replacement — unlike permanent couplings.
Our unions are designed for quick installation while maintaining high pressure and sealing integrity.
✅ Custom Manufacturing:
From small-diameter 1/8″ to large-size 6″ galvanized pipe connectors — we design and produce fittings according to drawings, samples, or special requirements.
