Weld neck flange connects pipes or valves through welding, providing high strength and excellent sealing performance.

Slip-on flanges slide over the pipe and are then welded in place. They are easy to install and align, suitable for low-pressure, low-temperature applications.

Plate flange is a common piping connection component that connects to pipes or equipment with bolts, providing a simple and reliable seal.

Socket weld flange is suitable for small diameter pipes and medium to high-pressure environments, providing good strength and sealing performance.

Threaded flange connects pipes via threading, typically used for low-temperature, low-pressure, small diameter pipes where welding is difficult.

Blind flange is used to seal the end of a pipe without connecting to other equipment, facilitating pipe inspection and maintenance.

A lap joint flange is used in conjunction with a stub end, suitable for pipes requiring frequent disassembly.

We can customize flanges in various sizes and specifications based on your drawings to ensure compatibility within the piping system.

Hot-dip galvanizing enhances steel pipes’ durability by providing strong corrosion resistance, ideal for various outdoor applications.

Epoxy coating enhances steel pipes’ durability, offering strong corrosion resistance, ideal for various industrial pipeline applications.

Three-Layer Polyethylene Coating (3LPE) enhances steel pipes’ durability with exceptional corrosion resistance for harsh environments.

Three-Layer Polypropylene Coating (3LPP) enhances steel pipes’ durability and high-temperature resistance, ideal for harsh environments.

Threading & coupling ensure reliable connections in steel pipes, enhancing flexibility and safety for efficient pipeline systems in various industries.

Laser cutting offers high precision and complex shape capabilities, while machine cutting is cost-effective for standard shapes in steel pipe processing.

Honing and grinding enhance steel pipes’ smoothness and accuracy, ensuring reliability in industries like petroleum and chemicals.
