Best Choice Of Pipe Fittings, Steel Fittings And Stainless Fittings
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.
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.
They can be tted either into the screwed joint or into specially made devices. In either case the cutting ring and its edges are moved axially as the union nut is tightened. 900#, 1500#, and 2500# stainless steel flanges are available. Call or email us for those or any custom stainless steel flanges. 18″, 24″, 36″, and 48″ lengths are stocked in addition to the standard stainless steel nipples.
In a long radius elbow, the centreline radius is 1.5 times the nominal size of the pipe or you can say 1.5 times the diameter of the pipe. Normally long radius elbows are used in piping as pressure loss is less as compared to short radius elbow. Elbows are available in two radius types, Short radius and Long Radius (1.5D).
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.
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.
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.
If both ends are the same gender, it is a gender-changing reducer. Insulating pipes is important when you’re working with refrigeration and heating systems. We stock Class O, plumbing pipe and lagging to help with insulation in all scenarios. In Eccentric reducer, the center of both ends is on different axis as shown in the image. When one of the outside surfaces of the pipeline is to be maintained the same, eccentric reducers are required. It is a type of Tee that has the branch at a 45° angle, or an angle other than 90°.
