We supply close, short, long, extra-long, and hex nipples from 1/8″ through 8″ NPS, in schedules ranging from SCH 40 to XXS.
ASTM A733 and ASME B1.20.1 (NPT) threaded nipples are leak-tight partners in piping.
304 and 316/316L stainless steel offer corrosion resistance in areas with chloride exposure.
Whether seamless or welded pipe nipples from ASTM A733, with threading on both ends (TBE) or one end (TOE).
BSP threading is available on request.
304 is a cost-effective material for HVAC and water treatment.
316 and 316L grades are used where elevated resistance to pitting and crevice corrosion.
Mill test reports (MTR) to EN 10204 3.1 are available with every order.
All products are traceable, and dimensional inspection is in-house before shipment.
We supply distributors, EPC contractors, and end-user facilities with no minimum order quantity on standard sizes.

I design our pipe nipples with standard NPT or BSP threads, making them easy to install using common pipe tools.
No welding, special equipment, or extensive training is required on-site.
This helps project teams complete pipeline connections quickly and safely.
Different materials perform differently in the same pipeline environment.
Galvanized Steel Pipe Nipple
Better corrosion resistance, widely used in fire sprinkler and water supply systems.
Carbon Steel Pipe Nipple
Lower cost option for gas pipelines and industrial mechanical systems.
Stainless Steel Pipe Nipple
Excellent corrosion resistance, ideal for chemical plants and food processing pipelines.
Brass Pipe Nipple
ASTM B43 pipe nipple has good sealing and corrosion resistance, and is commonly used in plumbing and light-duty systems.
Our factory produces seamless steel pipe nipples with stable quality and high output.
Monthly production capacity exceeds 800 tons, supporting both bulk orders and distribution supply.
Standard sizes are usually delivered within 15–25 days, and OEM customization is available.
Seamless pipe nipples are typically used together with other threaded pipe fittings:
Seamless pipe nipples are a key connector in threaded piping systems.
They can easily connect with pipe tees, couplings, unions, valves, and pipes to build a complete pipeline structure.
With standard NPT or BSP threads, contractors can quickly assemble flexible piping systems for water, gas, fire sprinkler, and industrial applications.
Pipe nipples provide a reliable threaded connection between pipes and fittings.
They are commonly used with tees and couplings to form complete pipeline systems.
This connection method allows distributors and contractors to quickly assemble piping networks on site.
Pipe nipples are commonly used in threaded piping systems together with couplings, tees, elbows, valves, and pipes.
These fittings enable the construction of complete threaded piping systems for industrial and commercial projects.
Seamless steel pipe nipples are available in a wide range of sizes and thread standards.
Common thread types include NPT, BSPT, and BSPP, meeting international piping standards.
Custom lengths and thread specifications are available according to project requirements.
As a professional stainless steel nipple manufacturer in China, we supply high-quality threaded pipe nipples used to connect or extend piping systems in water, oil, gas, and industrial applications.
Our stainless steel pipe nipple products are manufactured with precise threading and accurate dimensions to ensure tight sealing, easy installation, and reliable performance under demanding conditions.
With strict quality control across every production stage, we ensure consistency in bulk orders, making us a trusted pipe nipple manufacturer for global buyers.
As an experienced pipe nipple supplier, we also support OEM production and comply with international standards to meet different project requirements.
Carbon steel, stainless steel, and brass pipe nipples manufactured to ASTM standards. We supply contractors, distributors, and EPC firms across global markets with consistent quality and full traceability.
Yes, we specialize in bulk production for distributors, contractors, and industrial projects. Our factory ensures stable quality, consistent thread accuracy, and reliable delivery times.
A pipe nipple has external threads on both ends, while a pipe coupling has internal threads.
In most threaded piping systems, a pipe nipple connects two couplings or other female threaded fittings.
Yes, we manufacture threaded pipe fittings according to international standards, including NPT and BSP threads, ensuring compatibility with global piping systems.
