However, it has a high-pressure drop due to a sudden change in the direction of flow. The 90 reducing elbow is designed to change direction as well as reduce the size of the pipe within a piping system. The reducing elbow eliminates one pipe fitting and reduces the welding by more than one-third. Also, the gradual reduction in diameter throughout the arc of the reducing elbow provides lower resistance to flow and reduces the effect of stream turbulence and potential internal erosion. These features prevent sizeable pressure drops in the line.
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.
The ends may be machined for butt welding, threaded , or socketed. When the ends differ in size, it is known as a reducing elbow. From dependable compression fittings to soldier rings and press-fit elbows, our range of pipe fittings helps make sure you can finish the job properly.
Cutting rings with elasto- mer seal work according to the same functional principle, but they are furnished with additional elastomer seals to increase operating reliability further still. “Ordering was flawless, website straight to the point, shipping was quick and as stated, product was exactly as ordered.” Log in to TheConstructor to ask questions, answer people’s questions, write articles & connect with other people.

Major pressing of fittings to pipes or other fittings is performed using electrically powered press equipment, but mechanically driven press equipment is also available. Most of the major brands further have a plastic slip on the end of the press fittings allowing a simple identification if a press fitting has securely been installed. Further, the installation does not use any welding; press fittings with appropriate and region specific certification may be installed for gas lines.
The radius of curvature of a long-radius elbow is 1.5 times the pipe diameter, but a short-radius elbow has a radius equal to the pipe diameter. Short elbows, widely available, are typically used in pressurized systems, and in physically tight locations. 90 Degree elbow is installed between the pipe to change the direction of the pipe by 90 Degree.
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.
We know that the likes of water pipe, fittings, water meters, hose etc. are not the most glamorous products in the world, but this doesn’t make a difference to us when it comes to customer service. Whether you’re looking for a simple adaptor or specifying a whole pipework system, you’ll get all of our expertise and professional courtesy. Before installation, make sure the valve is in the “open” position and all cemented surfaces are clean and dry.
With high peak-flow volumes, the design and construction of these systems may resemble those of storm sewers. Never let that be the case with our selection of copper tubes, stainless steel tubes and different plastic pipe options. Long radius pipeline bends are used in fluid transportation lines which required pigging. Due to their long radius and smooth change of direction, the pipe bend has very less pressure drop, and a smooth flow of fluid & pig is possible.
The pressure losses that inevitably occur in pipeline systems can be recorded either by measuring equipment or by calculation. In order to achieve an optimum seal, conical screw-in threads must be provided with an additional sealing means, e.g., Teflon tape. Flare fittings were originally developed for high pressure applications and are used widely in locations that are exposed to strong vibrations. As the cutting ring moves along a precisely de ned assembly path, its cutting edges are forced into the surface of the hydraulic pipe.
The flare nut, which had previously been installed over the tubing, is then tightened over the fitting to force the tapered surfaces tightly together. Flare connectors are typically made of brass or plastic, but stainless steel or other materials may be used. A solvent is applied to PVC, CPVC, ABS or other plastic piping to partially dissolve and fuse the adjacent surfaces of piping and fitting. Solvent welding is usually used with a sleeve-type joint to connect pipe and fittings made of the same material.
