Where this configuration fits

Weld connections can be selected where the system layout calls for a welded tube transition. The completed assembly depends on both fitting selection and weld quality; the tube, weld and seals remain part of the pressure boundary.

Details to include in your enquiry

  • State tube outside diameter, wall thickness, material and weld-end preparation.
  • Select a nipple, a complete welding connector or a weld bulkhead arrangement.
  • Specify the welding procedure, inspection and documentation required by the project.
  • Follow the supplied procedure for protecting or removing seals during welding.

Sizes, materials and supplied condition

Specify the tube outside diameter, LL/L/S series, material and every connection. The overall catalogue covers 4–42 mm tube, but an individual configuration may have a narrower range. Carbon steel, 316L and 316Ti can be included in an enquiry, subject to confirmation of the supplied item.

State whether you require complete fittings or bodies only. Include working pressure, peak pressure, temperature, medium and any certificate requirements so the complete assembly can be checked.

Questions answered

How do I specify welding fittings?

Identify the configuration, tube diameter and series, all connection threads and seals, material, quantity and operating conditions. Send a marked sketch when port positions or different end sizes matter.

Are the catalogue dimensions suitable for final fabrication?

Use them to identify and enquire about the configuration. Obtain the order-specific drawing and confirmed pressure rating before fabrication or installation.
