The larger-diameter hub was also called a “bell” because of its shape. Adequate ventilation is essential to remove metal fumes from welding operations, and personal protective equipment must be worn. Because the high temperatures during welding can often generate intense ultraviolet light, dark goggles or full face shields must be used to protect the eyes.
They are categorized by application, such as isolation, throttling, and non-return. At BES, experience is everything, and our customer experience reflects as such.

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.

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°.
A nipple with continuous uninterrupted threading is known as a close nipple. Miter bends are not standard pipe fittings they are fabricated from pipes. Usually, they are preferred for size 10” & above because large size elbow is expensive.
Throttling valves are used to control the amount or pressure of a fluid allowed to pass through, and are designed to withstand the stress and wear caused by this type of operation. A double-tapped bushing is a fitting which serves as a reducer. It is a sleeve similar to a close nipple, but is threaded on both its inner and outer circumferences. Like a reducer, a double-tapped bushing has two threads of different sizes.
In Concentric reducer which is also known as a conical reducer, the center of both the ends is on the same axis. When the center lines of the larger pipe and smaller pipe are to be maintained the same, then concentric reducers are used.
Unlike metal welding, solvent welding is relatively easy to perform . Solvents typically used for plastics are usually toxic and may be carcinogenic and flammable, requiring adequate ventilation. In drainage systems, it is primarily used to connect horizontal drains to vertical drains. The center connection is generally to the pipe leading to a trap . It must not connect a vertical drain to a horizontal drain, because of the likelihood that solids will accumulate at the bottom of the junction and cause a blockage.
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.
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.
