2017-06-16 10:13:18 Pipe Fittings Suppliers

The flange fitting is a welded pipe. This pipe is used to match the pipe. There are processing, there is no processing. Some castings, is the flange together with the cast out. While the welding is the latter part of the processing. The factory can be processed and can be processed at the construction site. There are the size of the first flange pipe fittings, but also elbow, three-way flange fittings. Its material is also varied, there are carbon steel, alloy steel, stainless steel and so on.(flanged pipe fittings
Flange fittings
Flanged pipe fittings
Means a pipe with a flange (flange or plate).
It can be made of cast, but also by thread connection or welding composition. Implementation of national standards GB / T17185-1997, GB / T12459-2005, GB / T13401-2005 and other standards.
Overview of Flange Fittings
Flange (Flange) also known as flange or flange disk. A flange is a part that connects a pipe to a pipe and is connected to a pipe end. There are holes on the flange, the bolts make the two flanges tight. The flange is sealed with a gasket. Flange thread connection (wire) flange and welding flange.
2. Connect the pipe to a pipe part. Accordingto the connection method can be divided into socket-type pipe fittings,threaded fittings, flange fittings and welded pipe four categories. Use the same material as the tube. Elbow (elbow), flange, three-way tube, four-way tube (cross head) and reducer (size head) and so on. Elbowfor the corner of the pipe; the flange is used to make the pipe andpipe connected to each other parts, connected to the pipe end, threepipe for three pipe collection place; four pipe for four pipe collectionplace; The pipe is used for the connection of two pipes of different diameters.
Introduction to the type of flange
The flange is a flanged part. Flanges can be separate, called flanges, or can be combined, such as valve flanges, easy to install bolts. This article describes the flange of the material, sealing surfaceform and according to national standards and chemical, petrochemical,mechanical standard flange type.

Cast steel, alloy steel, stainless steel, copper, aluminum alloy,plastic, argon leaching, PVC, PPR, RFPP (reinforced polypropylene) andso on.
2. The production method can be divided into push, suppression, forging, casting and so on.
3. To the manufacturing standard can be divided into nationalstandard, electric standard, ship standard, standard, water standard,American standard, German standard, Japanese standard, Russian standardand so on.
4. According to its radius of curvature to points: can be divided into long radius elbow and short radius elbow. Longradius elbow refers to its curvature radius is equal to 1.5 times theouter diameter of the tube, that is R = 1.5D; short radius elbow thatits radius of curvature is equal to the outer diameter of the tube, thatis, R = 1.0D. (D is the elbow diameter, R is the radius of curvature).
5.According to the pressure level, there are about 17 species, and theAmerican pipe standard is the same, there are: Sch5s, Sch10s, Sch10,Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; the most commonly used are STD and XS.
