A degree of skill is needed to make a number of reliable soldered joints quickly

If flux residue is thoroughly cleaned, soldering can produce a long-lasting connection at low cost. However, the use of an open flame for heating joints can present fire and health hazards to building occupants, and requires adequate ventilation. Of course, they can be fitted on the standard threaded connectors, the end of the pipe just has to be provided with a stan- dardised 37° flare cone in preparation for fitting. If the pipes are not having special ends or plain ends then adaptors make them threaded either male or female whichever is needed.

The lighter rubber fittings may not muffle sound as well as the heavy cast-iron fittings. In addition, some conservative plumbing codes still require leaded hub joints for final connections where the sewer main leaves a building. Although low-priced wyes are often spot-welded, industrial-strength wyes are flash-welded at each seam. In long-distance pipeline applications, a specialized wye is used for allow insertion of pigging to keep pipes clear and maintain flow.

Wye tee allows one pipe to be joined to another at a 45° angle. This type of tee reduces friction and turbulence that could hamper the flow. A barred tee which is also known as a scrapper tee is used in pipelines that are pigged. The branch of the tee has a restriction bar welded internally to prevent the pig or scrapper to enter the branch. The bars are welded in the branch in a way that it will allow restriction free passage of the pig from the run pipe.

A threaded pipe has a screw thread at one or both ends for assembly. Crosses, also known as four-way fittings or cross branch lines, have one inlet and three outlets , and often have solvent-welded socket or female-threaded ends. Cross fittings may stress pipes as temperatures change, because they are at the center of four connection points.

This generally requires that the piping and fitting are the same material. Skill is required to melt the joint sufficiently to ensure good fusion, while not deforming or damaging the pieces being joined. A trap primer automatically injects water into a trap, maintaining a water seal to keep sewer gas out of buildings.

If the 3 sides of T-fitting are similar in size then it is called as Equal tee otherwise it is called as Unequal tee. The advantages of this method are durability, speed, neatness, and safety. Some crimped fittings are designed to be used with copper tubing, without requiring flux or filler metal. Although crimped fittings are suitable for drinking-water pipes and other hot-and-cold systems , they are substantially more expensive than sweated fittings. Where many connections must be made in a short period of time , soldering is quicker and less expensive joinery than compression or flare fittings.

They are categorized by application, such as isolation, throttling, and non-return. At BES, experience is everything, and our customer experience reflects as such.
