Product Description

Product Description

STAINLESS STEEL FLANGE
 
Stainless steel flanges in 304 / 316 / 304L / 316L offer a reliable, corrosion-resistant pipe and valve connection for industrial systems. 
 
Available in pressure Classes 150, 300, 600, 900, 1500, and 2500, these flanges support a wide range of operating conditions and meet common pipeline and vessel requirements. 
 
CNC turning ensures tight dimensional tolerances and consistent sealing surfaces, while OEM & ODM customization and 100% inspection before shipment guarantee the fit, finish, and quality customers expect. 

Product Categories

Stainless Steel Plate Type Slip-On Flanges

Featuring a flat plate design with a central bore slightly larger than the outer diameter of the pipe, these flanges slide over the pipe end and are welded both inside and outside for secure attachment.

Stainless Steel Weld Neck Flanges

Featuring a long tapered hub that gradually transitions from the flange thickness to the pipe wall, these flanges are butt-welded to the pipe, creating a seamless, high-strength connection with excellent stress distribution. 

Stainless Steel Slip-On Weld Neck Flanges

Featuring a short neck or hub that the pipe slips into before welding, these flanges offer improved stress distribution compared to standard flat plate flanges while remaining more economical than full weld neck designs.

Custom Stainless Steel Welded Flanges

Designed and fabricated according to your exact dimensional requirements, material specifications, and performance criteria, these flanges accommodate special bore sizes, unusual pressure ratings, custom bolt patterns, or unique connection configurations.

Custom Stainless Steel Blind Flanges

Unlike standard blind flanges, these custom solutions accommodate unusual pipe sizes, proprietary bolt patterns, special thickness requirements, or specific material grades to match your system's exact needs. 

Stainless Steel Lap Joint Flanges

This innovative configuration allows for easy bolt hole alignment without rotating the entire piping system, making installation and maintenance significantly easier, especially in tight spaces.

Stainless Steel Blind Flange Covers

These flat, disc-shaped flanges with bolt holes but no center bore are designed to permanently or temporarily close off piping systems, isolate sections during maintenance, or terminate pipeline runs.

Stainless Steel Pressure Gauge Connection Flanges

These specialized flanges feature threaded connections (NPT, BSPT, or metric) for direct gauge attachment, combined with standard flange bolt patterns for system integration.

Radar Level Gauge Custom Stainless Steel Flanges

These specialized flanges accommodate the unique mounting requirements of radar level transmitters, including proper sizing for antenna clearance, correct orientation for optimal signal transmission, and compatibility with various radar sensor designs from leading manufacturers.

MATERIAL OPTIONS & CORROSION RESISTANCE
 
Made from 304, 316, 304L, or 316L stainless steel, these flanges resist rust and chemical attack in challenging environments. The choice of grades lets you optimize for chloride resistance, weldability, and cost.

WIDE PRESSURE RANGE
 
Rated for Class150, 300, 600, 900, 1500, and 2500 service, the flanges cover low-pressure to high-pressure industrial applications. This flexibility reduces the need for multiple flange types across projects.

PRECISION CNC TURNING
 
CNC processing delivers consistent bolt-hole patterns, flatness, and concentricity for reliable gaskets and leak-free connections. Tight tolerances improve assembly speed and lower field rework.

CUSTOM SHAPES & SPECIFICATIONS
 
Fully customizable dimensions, face types (RF, FF, RTJ), and hole patterns to match ANSI/ASME and other specifications as required. OEM & ODM support means bespoke flange designs can be produced to your drawings.
