Custom non-standard flangesProcessing based on provided drawings and samplesCNC precision machining

Product Type

Customizable stainless steel flange types

Production should be organized according to the outer diameter, inner diameter, thickness, hole positions, and fit requirements on the drawings, rather than forcibly substituting with generic specifications.

01

Standard stainless steel flange

Manufactured according to common specifications, pressure ratings, or customer drawings. Material, thickness, and sealing surface type can be confirmed based on actual working conditions.

02

Non-standard custom flanges

Supports special outer diameters, inner holes, hole spacings, and mounting structures. Can perform machining and surface treatment based on provided drawings, according to equipment fit requirements.

03

Circular connecting flange

Suitable for mechanical connections, equipment installation, and structural fixing. The number of holes, hole diameter, countersunk holes, and threads can all be customized according to drawings.

04

Pipe connection flange

The material and structure are selected based on the pipe diameter, medium, and connection requirements. Sealing surfaces, bevels, and bolt holes can be machined.

05

Thick plate processing flange

Supports machining of inner and outer circles, planes, and holes after thick plates are cut. Roughing and finishing can be arranged according to tolerance requirements.

06

irregular structure flange

We accept non-circular contours, eccentric holes, and mounting ear structures. Materials and surface finishes can be selected according to the application environment.

Processing capacity

Not just flange blanks, but also precision machining.

Based on structural, quantity, and size requirements, select a solution for sheet metal cutting, precision casting, or assembly processing, and complete the key mating dimensions and surface treatment.

• Laser cutting/sawing
• Precision casting blank
• CNC turning
• CNC milling
• Drilling, tapping, countersinking, chamfering
• Machining of planes and inner and outer circles
• Polishing, sandblasting
• Surface treatments such as pickling and passivation

Quality control

The key points to consider in flange machining are the hole positions, thickness, flatness, and mating dimensions.

From material confirmation to finished product inspection, checks are conducted on assembly and sealing-related dimensions to reduce issues such as hole position deviations, poor fits, and surface burrs.

• Material spectral testing
• Outer diameter, inner hole, and thickness inspection
• Hole position and spacing inspection
• Flatness inspection
• Thread and countersunk hole inspection
• Surface burrs and visual inspection
• Provide testing records as required.
