Metal T Pipe Fitting Butt Welding Concentric Reducer Of Stainelss Steel Pipe

Product Specification

Metal t pipe fitting butt welding concentric reducer of stainelss steel pipe fittings

1,  The two ends of reducer have different diameters, which are used to connect pipes or flanges with different diameters for reducing.

2,  The orifices at both ends of the concentric reducer are on the same axis. When reducing, if the position of the pipe is calculated by the axis, the position of the pipe will not change. It is generally used for reducing of gas or vertical liquid pipe.

3,  The energy-saving and emission reduction effect of the reducer is more significant.

4,  The light and heat efficiency of the whole water heater can reach about 73% by adopting the reducer dense drainage technology, which not only saves power and coal, but also reduces carbon dioxide emissions.

5,  Both ends of the eccentric reducer are circumferentially cut, which is generally used for horizontal liquid pipeline.

6,  The selection of reducer can be based on the actual flow of the pipeline to select the corresponding caliber specification, and try to select the reducer with the same caliber specification as the process pipeline.

7,  Concentric reducer is beneficial to the flow of fluid, and it has less interference to the flow state when changing the diameter.

8,  Therefore, concentric reducer is used to change the diameter of gas and vertical flow liquid pipeline.

9,  The connection form of concentric reducer is directly butt welding reducer and steel pipe.

10,  The main manufacturing standards are generally GB / t12459, GB / T13401, ASME B16.9, SH3408, SH3409, HG / T21635, HG / T21631, SY / T0510.

Manufacturing process

11,  The forming methods of concentric reducer include reducing / expanding forming and stamping forming.

12,  The process of reducing / expanding is to put the tube blank with the same diameter as the big end of the reducing tube into the forming die.

13,  By pressing along the axial direction of the tube blank, the metal moves along the die cavity and shrinks.

14,  According to the size of reducer, it can be divided into one-time pressing forming or multiple pressing forming.

Application

1,  Stamping refers to the use of steel pipes as raw materials to produce small and large heads, and the use of stamping technology for the production of small and large heads of some specifications.

2,  The shape of the die used for drawing is designed according to the size of the inner surface of the head, and the steel plate after blanking is punched and drawn by the die.

3,  Stainless steel reducer has a wide range of applications in many fields, the main reason is the excellent performance of stainless steel.

4,  Stainless steel is one of the widely used metal materials at present, and corrosion resistance is an important index to measure stainless steel reducer.

5,  So the innovation direction is to improve its corrosion resistance stability without reducing the mechanical properties of stainless steel reducer.

6,  The stainless steel reducer has different application fields according to different materials. The main alloy element of ferritic stainless steel reducer is chromium.

7,  When more than 12% chromium is contained in the steel, the reducer of this kind of steel has better plasticity, but greater brittleness, superior anti-corrosion ability, and good anti stress corrosion cracking ability in the medium containing chloride.

8,  Therefore, it is often used in salt industry and various pipelines used to transport chloride.
