Stainless Steel Slip On Flange
Food and Beverages:Frequent disassembly and washing + hygiene dead corners
Biopharmaceuticals:CIP/SIP sterilization tolerance
Water treatment plant:Chloride ion corrosion + Quick repair
- Product Introduction
Products Description
Stainless Steel Slip On Flange is a type of welded stainless steel flange that is easy to install, provides a reliable seal, and is suitable for medium and low pressure and corrosive piping systems.
Products Advantages
High Corrosion Resistance
Made of 304/316 stainless steel (containing ≥18% Cr), it forms a passivation film to resist corrosion from acids, alkalis, seawater, and chemical media.
Stable Leakage Prevention
The sealing surface is CNC precision machined with a roughness controlled at Ra 1.6 μm, improving gasket fit and reducing the risk of leakage.
Precise Dimensions
Manufactured according to ASME / DIN / EN standards, with dimensional tolerances of approximately ±0.1 mm, suitable for various piping systems.
Customizable Range
Sizes: 1/2"–48", Class 150–600
Materials: 304, 316, 316L, 321, Duplex Stainless Steel
Sealing Surfaces: RF / FF / RTJ
Standards: ASME / DIN / EN / JIS
Surface Treatments: Pickling, Rust-preventive Oil, Sandblasting
Packaging and Transportation
Sealed protective cover + rust-preventive oil treatment
Reinforced wooden crates/pallets to prevent bumps and crush damage
Export wooden crates with a load capacity of ≥1 ton, suitable for long-distance sea freight
Shipping can be arranged according to the customer's freight forwarder; sea/air freight supported
