KNOWLEDGE

The weld neck flange features a long tapered hub for butt welding, ensuring strong structural integrity and excellent stress distribution. It minimizes leakage risks, ideal for high-pressure, high-temperature, and critical service applications.
It complies with standards like ANSI/ASME B16.5, DIN, EN 1092-1, and GOST , available in PN6-PN160 and DN15-DN5000, with materials including carbon steel, stainless steel, and alloy steel.
Widely used in oil and gas, petrochemical, power generation, and chemical processing industries.

Threaded flange has internal threads matching pipe threads, enabling easy installation without welding. It reduces damage to pipes and is suitable for low-pressure systems requiring frequent disassembly.
It complies with standards like ANSI/ASME B16.5, DIN, EN 1092-1, and GOST , available in PN6-PN160 and DN15-DN5000, with materials including carbon steel, stainless steel, and alloy steel.
Applied in water treatment, plumbing, low-pressure gas systems, and light industrial pipelines.

Slip on flange slides over the pipe and is welded on both sides, offering cost-effectiveness and easy alignment. It has moderate strength, suitable for medium-low pressure and non-critical services.
It complies with standards like ANSI/ASME B16.5, DIN, EN 1092-1, and GOST , available in PN6-PN160 and DN15-DN5000, with materials including carbon steel, stainless steel, and alloy steel.
Used in general manufacturing, water supply, heating, and low-pressure chemical pipelines.
