Joining Stainless Steel Pipe

The stainless steel being joined.

Joining stainless steel pipe.

Finally join the two ends with the large nut. There are three main methods of joining pipes together and attaching fittings to them. The use of victaulic couplings with ductile iron housings on stainless steel pipe is common practice when pipe material selection is based on compatibility with the fluid media and where the risk of external corrosion is low. Frp fiberglass reinforced plastic pipe.

Cpvc pvc chlorinated polyvinyl chloride polyvinyl chloride pipe. Arrange the fittings so the water flows past the threads on the male fitting not into them. Smaller lines are usually joined by socket welding or screwing. Stainless steel pipes and brass pipes and fittings work together better than stainless steel and copper.

Lines of 2 inch or larger are usually butt welded this being the most economic leak proof method. Apply pipe thread tape before screwing them together and then glue the pipes into the fittings using the proper cement. 304 stainless steel propress pipe is designed to join with viega propress fittings and ball valves quickly and reliably with no welding required. However the chicago plumber installing the stainless steel and brass pipes and fittings needs to pay attention to which types of stainless steel he or she is using.

Soldering like brazing uses filler alloys with lower melting points than the parent metal i e. Temperatures are typically below 450 c for soldering stainless steels. Victaulic pipe joining couplings are also used to join multiple pipe materials including. Soldering is often used for joining stainless steel in applications such as roofing and water tubing plumbing.

Tighten first with pliers then with pipe wrench. Use sandpaper as needed for cleaning pipe then take the union apart and solder the brass end to the copper and screw the steel end to the galvanized pipe. Install the lower half of the dielectric union to steel pipe. Stainless steels are weldable materials and a welded joint can provide optimum corrosion resistance strength and fabrication econom y.

Required tools for this project. Solder coupling and small length of pipe to end of existing copper water pipe. Add a new galvanized steel pipe length nipple at each end and solder in your copper. One inexpensive method of connecting abs to pvc drainpipes is to use male and female fittings.

In the fabrication of stainless steel products components or equipment manufacturers employ welding as the principal joining method. Use with press tools available separately. Despite being dissimilar metals couplings with ductile iron housings can be the best overall choice for joining stainless steel pipes.
