Short radius elbows are used under limited space applications. 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.
Both McAlpine and Aquaflow pipes can be moulded with heat. Join waste pipes simply and effectively in bathrooms, kitchens, utility rooms and en-suites by using the solvent weld method. Our range of solvent weld pipe and solvent weld fittings are popular with tradesmen and plumbers. We stock a huge selection of solvent weld pipe fittings in a variety of sizes from 30mm to 50mm. Securely attach waste pipe to floors, ceilings or walls using a compatible pipe clip or alternatively, direct the waste pipe around bends or corners with a pipe bend at 90, 92.5 or 135 degrees.
An advantage of this type of fitting is that the pipe it is connecting to does not need to be cut to a precise length; the slip joint can attach within a range of the end of the inserting pipe. Many slip fittings may be tightened or loosened by hand, for easier access to residential drainpipe systems . Because they operate at low pressure and rely on gravity to move fluids , drain-waste-vent systems use fittings whose interior surfaces are as smooth as possible. Freshly cut ends of pipe segments are carefully deburred to remove projecting slivers of material which may snag debris which can build up to cause blockages. This internal smoothness also makes it easier to “snake out” or “rod out” a clogged pipe with a plumber’s snake. An elbow is installed between two lengths of pipe to allow a change of direction, usually a 90° or 45° angle; 22.5° elbows are also available.
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.
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.

A reducer can also be used either as a nozzle or diffuser, depending on the mach number of the flow. Dielectric unions, with dielectric insulation, separate dissimilar metals to prevent galvanic corrosion. When two dissimilar metals are in contact with an electrically conductive solution , they form an electrochemical couple which generates a voltage by electrolysis. When the metals are in direct contact with each other, the electric current from one to the other also moves metallic ions from one to the other; this dissolves one metal, depositing it on the other. A dielectric union breaks the electrical path with a plastic liner between its halves, limiting galvanic corrosion.
Lightly lubricate the thread and cone of the assembly stud and the thread of the union nut. However, the O-ring must be removed before welding, and any stray welding material must be removed from the O-ring groove and the fitting hole. Plug is a component of plumbing component which is generally used to close pipe opening during inspections and repairs. In use, the spigot of one segment was placed into the socket of the preceding one and a ring of oakum was forced down into the joint with a caulking iron. Ideally, this would be done by pouring in molten lead, allowing it to set, and hammering it tightly with a caulking tool. If this was not possible due to position or some other constraint, the joint could alternatively be filled with lead wool or rope, which was forcibly compacted one layer at a time.
