High Precision Cast Transition Flange for Industrial Pump Valve Pipeline Connection

Made of high-grade SS304/SS316 stainless steel via lost-wax investment casting, dense internal structure, excellent corrosion and acid resistance for harsh working conditions.

The precision investment casting process achieves high dimensional accuracy and fine surface finish, effectively reduces post-machining allowance, and lowers production cost.

An integral two-step reducing structure provides a transition connection between different pipe diameters or between equipment and pipelines, with strong versatility.

All sealing surfaces and bolt holes are precision CNC machined, with strict flatness and dimensional tolerance control, ensuring reliable zero-leakage sealing under high pressure.

Standard bolt hole distribution, compatible with ANSI, DIN, GB, and other mainstream flange standards, is convenient for on-site pipeline assembly and replacement.

The one-piece casting structure, without welding seams, stably withstands high pressure and impact loads, with no risk of fracture or leakage during long-term operation.

Smooth internal flow channel, low fluid resistance, reduces pipeline pressure loss and improves medium conveying efficiency.

Strict full-process quality control, non-destructive testing, and hydraulic pressure testing for each piece eliminate casting defects and guarantee stable batch quality.

Strong customization capability, producing flanges of various sizes, pressure ratings, and structures strictly according to customer drawings and requirements.

Wide application range; widely used in pump-valve matching, the chemical industry, water treatment, hydraulic systems, and other industrial pipeline projects.
