Weld Liner

Integraflow offers a complete range of DIN Imperial Liners, also known as DIN Male Parts, specifically designed to be welded into imperial OD stainless steel tube. These liners form the male half of a DIN 11851-style hygienic union, providing a clean, secure, and CIP/SIP-compatible seal when used with matching DIN imperial ferrules, seals, and nuts.

Manufactured from 316L stainless steel, each liner is machined for accurate imperial pipe fitment, making it the ideal choice for hygienic systems built around inch-based tubing common in the UK.

Product features:

  • Suitable for 1” to 4” imperial outside diameter tube

  • Weld-ready connection with smooth bore for hygienic flow

  • Internal polish typically to Ra ≤ 0.8 μm for hygienic applications

  • Compatible with DIN 11851-style nuts and ferrules

  • Designed for use in CIP/SIP environments

Applications:

  • Food and dairy processing plants

  • Beverage, brewery, and bottling facilities

  • Pharmaceutical and cosmetics production

  • UK-based or legacy hygienic installations using imperial tube

All DIN Imperial Liners are fully batch traceable, certified to meet hygienic process standards, and available for fast UK-wide dispatch from Integraflow – your reliable source for hygienic imperial pipework components.
