Stainless Steel Weld Reducer

Stainless Steel weld reducer is also called butt welding reducing pipe, can also be called variable pipe, size head, reducing pipe.The forming technology of reducing pipe size head is divided into two kinds: steel plate rolling welding forming, after steel plate blanking, by the rolling machine rolling and welding forming.The steel pipe may be molded by kneading.The steel tube is heated and the thick defensive abrasive is kneaded into shape.

The size of the small and large heads made of steel coils cannot be less than 159mm, the height is less than 1800mm, and the T-welding technology is required for welding and forming. The diameter of the reducer of the steel pipe is not larger than 159mm. The height cannot be higher than 500-1000mm. Cutting this technology is easy to appear corrugated when the height is too high. The size of the welding head must be determined: large head diameter, small head diameter, height dimension, and plate thickness dimension. The diameter must also be specified as the outer or inner diameter sizes.

Application of ss reducer (large and small head):

1. When there is a change in the flow rate of the fluid in the pipeline, such as an increase or decrease, and a small change in the flow rate requirements, a reducer must be used; 2. At the inlet of the pump, in order to prevent cavitation, reducers need to be used; 3. At the joints with meters, such as flow meters and regulating valves, reducers need to be used in order to cooperate with the joints of the meter.

Butt-welding big and small heads are also called reducer, reducer, big and small, and some people call them reducer. The big and small heads are rolled and welded by steel plates, and there is one or two welds. The performance standards refer to GB / T13401. In general, the diameter of the two ports of the big and small heads is between 200mm-2000mm, and the height of the reducer is within 1800mm. Some can be welded in several sections.
