FAQ

Pipe cross comes into equal cross and reducing cross,and the raw materials of which include a wide range, like carbon steel, alloy steel, stainless steel, low temperature steel, and high performance steel, etc. Our pipe crosses feature high strength, good toughness and resistance to corrosion, and they are widely used in many industries, such as petroleum, power generation, natural gas, chemical, shipbuilding, paper making etc.

Pipe Cross Types

Equal Cross

The equal pipe cross is one type of the pipe cross, just like a equal tee, the equal crosses means all the 4 ends of the cross are in same diameter. The pipe cross, like a road cross, is the joint of 4 pipes. Receiving the pressure from the 4 pipes, the weld joint between the pipes and cross must be very strong.

Reducing cross

The Reducing Cross Pipe Fitting also called as unequal pipe cross, it is the pipe cross which have four branch ends are not in the same diameters.

What types of Steel Pipe Fittings do you supply?

We supply a comprehensive range of steel pipe fittings designed to connect, control, change direction, or branch off piping systems. Our main product categories include:
Elbows (90°, 45°, 180°): Used to change the direction of the pipe flow.
Tees (Equal, Reducing): Used to combine or split fluid flow.
Reducers (Concentric, Eccentric): Used to connect pipes of different diameters.
Caps: Used to seal the end of a pipe.
Couplings & Unions: Used to connect two pipes in a straight line.
Crosses: Four-way fittings used in fire sprinkler systems and other specific applications.
We manufacture these fittings in various materials including Carbon Steel, Stainless Steel (304/316), and Alloy Steel.

What standards and specifications do your fittings meet?

Our steel pipe fittings are manufactured in strict compliance with international standards to ensure compatibility and safety in global projects. Key standards include:
ASME/ANSI B16.9: Factory-made wrought buttwelding fittings.
ASME/ANSI B16.11: Forged fittings, socket-welding, and threaded.
MSS SP-75: Specification for high-test, wrought, buttwelding fittings.
DIN / EN: European standard fittings (e.g., DIN 2605, DIN 2616).
JIS B2311/B2312: Japanese Industrial Standards.
GB/T 12459: Chinese national standard for steel pipe fittings.

What is the difference between Buttweld, Socket Weld, and Threaded fittings?

Choosing the right connection type is critical for your piping system's integrity:
Buttweld Fittings: Welded directly to the pipe. They provide a permanent, leak-proof connection and are ideal for high-pressure and high-temperature applications. They are commonly used in industrial pipelines.
Socket Weld Fittings: The pipe is inserted into a recessed area of the fitting before welding. These are typically used for small-bore piping (usually under 2 inches) and high-pressure systems where disassembly is not required.
Threaded (Screwed) Fittings: These have internal or external threads and are screwed onto the pipe. They are easy to install and disassemble, making them suitable for low-pressure water lines or maintenance-heavy areas, but not recommended for high vibration or high temperature environments.

What materials are available for your fittings?

We offer fittings in a wide range of grades to suit different environments:
Carbon Steel: ASTM A234 WPB (most common for general use), WPC, and low-temperature carbon steel (ASTM A420 WPL6).
Stainless Steel: ASTM A403 WP304/L, WP316/L, WP310, WP321, etc., ideal for corrosive environments and food processing.
Alloy Steel: ASTM A234 WP11, WP22, WP91, designed for high-temperature and high-pressure service (e.g., power plants).
Duplex & Super Duplex: For extreme corrosion resistance applications (offshore oil & gas).

Do you offer custom manufacturing or OEM services?

Yes, we specialize in both standard and custom manufacturing.
OEM Services: We can produce fittings according to your specific drawings or samples, including non-standard sizes or special beveling.
Custom Coatings: We can apply epoxy coating, galvanization, or oil varnish based on your project's corrosion protection requirements.
MOQ: For standard items, we have flexible MOQs. For custom forged or machined parts, the Minimum Order Quantity (MOQ) depends on the complexity of the production run.
