Reducer is a kind of pipe fittings used in pipe size

Seamless reducer

Reducer is a kind of pipe fittings used in pipe size. Usually adopted for reducing the forming process of pressing, expanding to suppress or reducing and expanding, to certain specifications of the reducer and stamping can be applied.

Reducing diameter

Size reducing forming technology of the head is with the head big end diameter equal to the size of the pipe into the forming die, along the axial direction of tube billet by pressing, shrink along the cavity movement and metal forming. According to the size of the reducer, divided into the one of pressing or more press forming.

stamping

Besides using steel as raw material to produce the size of the head, on the part of the specifications of the size of the head can also be used steel plate stamping forming technology is adopted to improve the production. Used by stretching die shape inner surface size design with reference to the size of the head, use after blanking punching die, stamping steel stretch forming.

steel elbow

Long-term storage of stainless steel elbow, should be regularly checked, often on the exposed surface must be kept clean, remove dirt, neatly stored in a dry and ventilated indoor place, is strictly prohibited stacking or open storage.Often keep the stainless steel elbow dry and Ventilate, keep the clean and tidy, according to the correct storage method of storage

Welding neck flanges

The heavy welding neck flanges are also named heavy WN flanges, which are

hot formed from a circular section of steel plate having a very small co-axial

hole in the flange center. The steel around the hole is shear-formed downward

and outward by a tapered die plug which is forced by the small hole forming an

integral neck on the weld neck flange. A supporting ring die is radiused at its

inner corner to form a suitable fillet radius at the junction of the neck with

the flange proper. A suitable pre-forming or post-forming operation may be

required to compensate for any deflection in the work piece out of planar

configuration.

Manhole flange

FLANGEManhole flange according to the division it can be divided into

through-hole, three holes, four holes and oblique through-hole man, specifically

in Table 1 below. Among them, oblique through the hole is divided into 15 °, 30

°, 45 °, 60 °, 75 ° total of five. The angle of each oblique through hole can be

applied within ± 7.5

Bend Pipe

The flow in centrifugal fan and 90° bend pipe was simulated numerically by the RNG k-turbulent model in software Fluent, and obtained the distribution diagram of the pressure and velocity. From the distribution diagram of the pressure and velocity, for measurement, three measurement points must be chosen, and two of them should be closed to the wall of pipe. However, in order to insure the measure accuracy, five or six measure points should be chosen. In addition, the velocity distribution of pipe bending reaches well-distibuted at the 1000 mm away from pipe exports. That is fluid flowing after through the flow field of bending section tends to uniform soon, so for the greater curvature bend pipe, measurement is more convenient.

Welded Steel Pipe fittings

As the development of pipe industry, pipe and pipe fittings, including pipe coupling, pipe tee, pipe elbow are more and more widely use in industrial area. There are four types of welded steel pipe that are mostly used:
1. Welded steel pipe: it is also called welded pipe. It is shaped by steel plate or steel strip through bending and then welding. It is divided into seam welded pipe and spiral welded pipe. According to the application, it is divided into general welded pipe, galvanized welded pipe, oxygen blowing metric welded pipe, welded pipe, wire casing, roller tube, deep well pump pipe, auto tube, transformer, electric welding thin wall pipe, welded pipe and spiral welded pipe.

2. General welded pipe: general welding work for low pressure liquid. It uses Q195A, Q215A, Q235A steel and adopt other mild steel welding for manufacturing. Steel pipe needs to be tested through pipe pressure, bending, flattening and some experiments, and there are some specific requirements for the surface quality. Usually the delivery length is for 4 to 10m. Welded pipe wall thickness is divided into two kinds: thread steel pipe and threadless steel pipe.

3. Seamless pipe: with increasing tube welding technology and simple processing, now seamless pipe has been replaced by welded pipe. Welded pipe producing capacity has been more than 219 mm (8 inches).

4. Oxygen tube welding: it is used for steelmaking oxygen tube. It generally uses small diameter welding pipe. Its specifications range from 3/8 inch to 2 inch. The welding is made of With 8, 10, 15, 20, or Q195 steel strip. For corrosion protection, some of them need aluminized processing.

Bend or Elbow

13-1045763-4863007
Bend is a common term for any kind of countered or turnabout in the piping. It is an unclear term that additionally consists of elbow joints.<br />
An elbow is a design term as well as they are categorized as 90 deg or 45 deg, brief or lengthy span.<br />
Elbow joints have commercial requirements as well as have restrictions to dimension, bend distance and also angle. The angles are normally 45 deg or 90 levels. All others offsets are identified as pipeline flexes.<br />
Bends are usually made or produced according to the requirement of the piping; nevertheless elbow joints are pre made and also basic, and also are offered off the rack.<br />
Bends are never ever sharp edges yet arm joints are. Pipeline flexing strategies have restraint about just how much product thinning could be enabled to securely have the stress of the liquid to be had. As elbow joints are pre made, cast or butt bonded, they could be sharp like appropriate angles as well as return arm joints which are 180 levels.<br />
Elbow is a basic fitting yet bends are customized made.<br />
In bends as the pipeline is curved as well as there is no welding entailed, there is much less pipeline rubbing as well as circulation is smoother. In elbow joints, the welding could develop some rubbing.<br />
All elbow joints are bends yet all bends are not arm joints.<br />
Bend has a bigger distance after that joints.<br />
Typically one of the most fundamental distinction is the span of curvature. Joints normally have span of curvature in between one to two times the size of the pipeline. Bends have a distance of curvature greater than two times the size.
