Threaded Pipe Fittings

Threaded pipe fittings are used to connect piping systems through threaded connections. By engaging internal and external threads, they securely connect valves, pipes, instruments, and other components to form a complete piping system.
They include various types such as elbows, tees, couplings, unions, caps, male and female threaded fittings, and more. As essential connection components for threaded piping systems, threaded pipe fittings offer convenient installation and disassembly and are widely used in small-diameter piping applications.
Features:
● Utilizes a threaded connection design for easy installation and disassembly—no welding required;
● Compact structure with a small footprint;
● Excellent sealing performance and high compatibility with threaded valves;
● Material: Available in 201, 304, or 316 stainless steel to meet various corrosion resistance requirements;
● Suitable for low-to-medium pressure applications; easy to inspect and maintain.

● Applications: Widely used in sectors such as petroleum, chemicals, water treatment, electromechanical equipment, instrumentation piping, food and pharmaceuticals, marine engineering, and HVAC; primarily utilized in small-bore threaded piping systems (DN8–DN100).

Q: What type of company are you?: A: We are an integrated manufacturer and trader (industrial and trading).

Q: What types of valves do you produce?: A: We specialize in producing threaded gate valves, globe valves, check valves, ball valves, strainers/filters, and more. We can also manufacture non‑standard products according to customer requirements. Our valves are available in three pressure‑rating grades to suit different pipeline working conditions: Light‑duty PN10, Medium‑duty PN16, and Heavy‑duty PN25. The higher the grade, the greater the wall thickness, pressure‑bearing capacity, and structural stability. Customers can select the appropriate grade based on their project’s pipeline pressure and operating environment.

Q: What are the common materials used for your valves?: A: We offer 201 stainless steel, 304 stainless steel, and 316 stainless steel to meet different anti‑corrosion, weather‑resistance, and media requirements.
● 201 is cost‑effective and suitable for general residential use, HVAC, and clean water applications.
● 304 offers good corrosion resistance and stability, widely used in water treatment, municipal projects, and general chemical scenarios.
● 316 provides stronger acid and alkali resistance, ideal for demanding conditions in chemical, pharmaceutical, and fluid‑handling systems with complex media.
All raw materials are inspected upon incoming receipt. The standard working temperature range is 0°C to 80°C, and we also support custom material specifications upon request.

Q: In which industries and applications are your products mainly used?: A: Our valves are suitable for a wide range of applications, including petroleum, chemical, natural gas, industrial water treatment, municipal water supply and drainage, HVAC engineering, pharmaceuticals, food & beverage, dairy, and many other fluid control systems. They are compatible with most conventional industrial and civil pipeline projects.
