Weld Liner

Integraflow supplies precision-engineered SMS Weld Liners, also known as SMS Male Parts, used in hygienic pipeline systems conforming to the Swedish Manufacturing Standard (SMS 1145). These liners form the male half of an SMS union, providing a smooth hygienic bore and secure connection when paired with an SMS ferrule, nut, and gasket.

Each liner is designed for orbital or manual welding into stainless steel tube, creating a flush internal bore for easy cleaning and product flow.

Product features:

  • Manufactured from 316L stainless steel for corrosion resistance and hygienic performance

  • Polished internal surface finish (typically Ra ≤ 0.8 μm) for clean-in-place (CIP) and sterilise-in-place (SIP) compatibility

  • Available in sizes from DN25 (1”) to DN100 (4”)

  • Designed for use with standard SMS union seals and nuts

  • Suitable for use with ISO, DIN, or BS tube on request

Applications:

  • Food & beverage process lines

  • Dairy and milk transfer systems

  • Cosmetic and pharmaceutical production

  • Hygienic pipework systems requiring frequent assembly/disassembly

All weld liners are fully traceable and available for fast UK-wide dispatch from Integraflow – your trusted supplier for hygienic process fittings.
