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 […]

Analysis of the installation case of spiral wound gaskets

Large diameter spiral wound gaskets are key sealing elements for heat exchanger channel flanges. In order to minimize seal failure at the heat exchanger channel flange, it is important to properly install the spiral wound gasket and apply the correct bolt tightening sequence and proper tightening torque. 1 Question raised An industrial refrigeration project exported to Kazakhstan, the U-tube heat exchanger, according to GB 151 for the heat exchanger, its model is BIU1500-8.3/2.07-1142-7/19-2 (As shown in Figure 1), the design pressure is 8.3 MPa, the hydraulic pressure test pressure is 10.8 MPa; the full thread bolt is M64×3, the length […]

What is a steel tee

What is a steel tee? The steel tee is a pipe fitting and a pipe joint. Used to change the direction of the fluid, used in the branch pipe of the main pipe. The three-way is a chemical pipe fitting with three openings, namely one inlet and two outlets; or two inlets and one outlet, having T-shaped and Y-shaped shapes, with equal-diameter nozzles and different diameter nozzles. Three identical or different pipeline collections. Classification of pipe tees What is an equal tee What is a reducing tee What is a lateral tee What is a barred tee What is a […]

ASME B16.34 – Group, Pres-Temp Rating

ASME B16.34 Valves Flanged, Threaded and Welding End applies to new construction. It covers pressure-temperature ratings, dimensions, tolerances, materials, nondestructive examination requirements, testing, and marking for cast, forged, and fabricated flanged, threaded, and welding end and wafer or flangeless valves of steel, nickel-base alloys, and other alloys shown in Table 1. Wafer or flangeless valves, bolted or through-bolt types, that are installed between flanges or against a flange are treated as flanged-end valves. Alternative rules for NPS 2½ and smaller valves are given in Mandatory Appendix V.  This Standard is to be used in conjunction with equipment described in other […]

Flange production and processing technology

Flanges have a variety of connection methods. According to different industry standards, they can be divided into a variety of flanges. The materials, processing forms and processes are different. The production and processing of flanges are mainly divided into forging, casting and cutting. These four systems are made and rolled. Material Alloy Steel: ASTM A182 F1, F5a, F9, F11, F12, F22, F91, A182F12, A182F11, 16MnR, Cr5Mo, 12Cr1MoV, 15CrMo, 12Cr2Mo1, A335P22, Carbon Steel: ASTM A105, 20#, Q235, 16Mn, ASTM A350 LF1, LF2 CL1/CL2, LF3 CL1/CL2, ASTM A694 F42, F46, F48, F50, F52, F56, F60, F65, F70 ; Common pressure levels: PN6, […]
