Tubefit engineers is engaged and expertise in the business of manufacturing the tube fittings, pipe fittings, industrial valves, instrumentation valves, air headers & condensate pots, manifolds etc.
Tubefit weld fittings join tubing or pipe to the adapter by butting the material to the fitting or by inserting the tubing or pipe into a socket in the fitting. Only type 316l stainless steel should be specified for weld fittings. This low carbon stainless steel [denoted by the suffix "l"] minimizes post-welding corrosion called inter granular corrosion. Tubefit weld fittings provide permanent welded connections for critical applications involving corrosive fluids, shock from pressure surges, temperature cycling, and system vibration.
Pre-assembly before welding: A unique feature of tubefit weld fittings and adapters is a tapered tube socket that facilitates system assembly. The taper holds the tubing in place prior to welding, allowing pre assembly of several tubing runs.
Technical information: The choice of fitting material and material being welded is critical. Using the same materials will ensure the same coefficients of expansion, reducing the possibilities of poor welds, out-of-roundness or dimensional changes that are detrimental to a good weld connection.
Standard material Is 316 stainless steel [ss]. Fittings made from barstock are manufactured from materials in accordance with asme sa-479 and astm a-276. Shaped fittings are manufactured from material in accordance with asme sa-182 and astm a-314. Pipe threads meet or exceed requirements of ansi b1.20.1 [npt] and mil-p-7105 b [anpt] for tapered pipe threads.
Pressure ratings: Pressure ratings listed for tubefit weld fittings are calculated in accordance with pressure piping code ansi b31.1. All working pressures listed are at 4:1 safety factor for 316 stainless steel.
