Vibration analysis of pressure pipeline

In industrial production, the pressure pipeline used is affected by the environment itself and the external environment, causing the pipeline to cause vibration. If the pipeline is affected by vibration for a long time, the fatigue will be generated at the location where the stress is concentrated, and the pipeline will be broken. Causes more serious safety accidents, which causes the leakage of the medium. Therefore, the vibration of the pipeline should be minimized during production to avoid unnecessary safety accidents. 1 Analysis of the vibration source of the pressure pipeline The pipes, supports and connected equipment of the pressure […]

What is a nipolet?

What is a nipolet? Nipolet is a one piece fitting for valve take-offs, drains and vents. Manufactured for Extra Strong and Double Extra Strong applications in 3.1/2in to 6.1/2in lengths. Available with male-socket-weld or male threaded outlets. Nipple Olets are known as branch connection fittings used to provide an outlet from a larger pipe to a smaller one. Nipolet uses the fundamental Weldolet however the branch affixes by method for an attachment inside the olet. The bore matches the outlet bore, and the existence of a counter bore roughly the size of the OD of the outlet provides a socket […]

What are socket weld fittings

What are socket weld fittings?    Socket weld fittings are pipe joints machined by round steel or steel ingots, the connection form is Socket Welding-SW, and the steel pipes are inserted into the socket to be welded. Socket elbow Socket tee Y–tee Socket pipe coupling Pipe Cap Pipe plug Hex Head Bushing Swage Nipples Sockolet Union Threaded pipe nipple Socket welding The types of socket fittings include 45° elbow , 90° elbow , tee , cross, 45° oblique tee, double socket pipe hoop, single socket pipe hoop, pipe cap, union, branch pipe, etc. . Among them, the three-way and the four-way have the equal diameter and the different diameter; the double-bearing pipe […]

Pipeline valve installation

1 Valve installation position must be convenient for operation Even if the installation is temporarily difficult, it is necessary to think about the long-term work of the operator. It is best to have the valve handwheel and the chest (usually 1.2 meters away from the operating floor), so that the opening and closing of the valve is more labor-saving. The floor valve hand wheel should be facing up, do not tilt, so as to avoid awkward operation. The valve against the wall machine should also leave room for the operator to stand. It is necessary to avoid the operation of […]

What is a threadolet?

What is a threadolet? A threadolet is the same basic design as a “weldolet.” However the main difference is the fitting has a female threaded connection to mate to the branch connection. This makes a 90° branch and comes in full size or reducing for a straight piece of pipe. It typically is in the size range of 1/2″ to 2″ and is welded over a hole either drilled or burned in the pipe.  You use a “weldolet” when you want to weld a steel pipe or pipe fitting directly to the branch fitting and a “threadolet” when you want to […]

What is a weldolet?

What is a weldolet? A Weldolet has beveled ends at both ends and is, therefore, welded onto the run pipe on one side and onto the branch pipe on the other side. Weldolets are used to create a 90-degrees (reinforced) pipe branch. The shape of the weldolet ensures little stress concentration on the branched pipe, providing an integral reinforcement. On the branch pipe side, Weldolets may have the same schedule of the run pipe or a higher schedule. It Comes in full size or reducing size (Full size is when you take branch of the same size as run pipe […]

What is a sockolet?

What is a sockolet? The sockolet (socket weld outlet) is mainly used for the reinforcing pipe fittings connected by the branch pipe, instead of using the branch pipe type such as the reducer, the reinforcing plate and the reinforcing pipe section, it is safe and reliable, reduces the cost, simple construction, improves the medium flow channel, and series. The advantages of standardization, design and selection are convenient, especially in high-pressure, high-temperature, large-diameter, thick-walled pipelines, which replaces the traditional branch pipe connection method. The main body of the branch pipe is made of high-quality forgings, and the materials are the same […]
