Notices in Pipeline Construction of Forged Steel Valves

Forged steel valves are mainly used in pipelines of various systems in thermal power plants, and can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, mud, oil, liquid metal and radioactive media. Compared with other valve products, forged steel valves are characterized by high temperature and pressure resistance, unique self-sealing design, the higher the pressure, the more reliable the sealing. Because of the special performance, technical characteristics and working conditions, the products also have the characteristics that other products can not replace. Forged steel valves can be classified as forged […]

What are ball valves?

What are ball valves? Ball valves are evolved from cock valves. It has the same 90 degree rotation action, the difference is that the ball valve is a sphere, with a circular through hole or channel through its axis. The ratio of spherical surface to passage should be the same, that is, when the sphere rotates 90 degrees, all spherical surfaces should be present at the inlet and outlet, so as to cut off the flow. Ball valves can be closed tightly with only 90 degrees of rotation and a small moment of rotation. Fully equal inner chamber of the valve body […]

What is a slip on flange?

What is a slip on flange? Slip On flange or SO flange is designed to slip over the outside of pipe, long-tangent elbow, reducer, and swage. The flange has poor resistance to shock and vibration. It is easier to align than a weld neck flange. This flange is ideal for low pressure applications since the strength when under internal pressure is about one third that of a weld neck flange. This flange has a raised face. Slip On flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for our customers. […]

What is an elbolet?

What is an elbolet? Elbolet is used on 90° Long Radius Elbows (can be manufactured for Short Radius Elbows) for thermowell and instrumentation connections. Available butt-weld to meet specific reinforcement requirements, and 3000# and 6000# classes for Socket Weld and threaded applications. An Elbolet is used on 90° long radius elbows, short radius elbows and can be used on 180° returns. However, an Elbolet on a short radius elbow is not used often. It typically is used for Thermowell and instrumentation connections but can be used as a drain connection when room isn’t available for using a Weldolet. The Elbolet […]

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 latrolet?

What is a latrolet? Latrolet that is used for taking branch which is not at 90 degrees to run pipe. Latrolet comes in a 45°or any other special degree as required by purchaser. End connections of a Latrolet can be butt welded, socket welded or threaded. They are available with butt weld connections to meet demanding reinforcement requirements or with socket weld/threaded connections in classes 3000# or 6000#. Material: A. Stainless steel: F304, F316L, F310S, F317L, F321, F347 B. Carbon steel: A105, A106, A53, A234 WPB C. Alloy steel: LF2, F5, F9, F11, F22 D. Duplex steel: F44, F51, F53, […]

What is a sweepolet?

What is a sweepolet? Sweepolet® is a contoured, integrally reinforced, butt-weld branch connection with a low stress intensification factor for low stresses and long fatigue life. The attachment weld is easily examined by radiography, ultrasound and other standard non-destructive techniques. Manufactured to meet your specific reinforcement requirements. The sweepolet is an alternative product of the existing steel tee, which is highly praised by the domestic and foreign markets for its flexibility in use. Large diameter change, wide range of diameter change, special plug in saddle, good sealing, non-stop gas operation, low operating cost, short time, high safety; no need to cut […]

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 […]
