Alloy steel reducer

Alloy steel pipe with different diameter is also called the big head, used to connect the different sizes of the pipe; generally it is divided into concentric different diameter pipe and eccentric different diameter pipe two, when the projection of different diameter pipe set up after the two port is concentric circles, it is called concentric reducer, and eccentric different diameter pipe is the projection of a the small inner tangential to the outer circle.

The size of the alloy steel reducer is different, the connecting pipe is also different, suitable for the industry is also different. In electric power, mining, metallurgy, material transfer, output, is used in short distance, high pressure transmission pipeline, under considerable pressure, and subjected to serious wear, pipeline single material is difficult to meet the conditions, especially the elbow, reducer, stamping elbow fittings for considering the safety of its use, and the service life, focus on improving the pipe lining toughness, impact resistance, and abrasion resistance. At the same time, the whole strength problem of pipeline and elbow should be considered.

Before the bonding of the alloy steel reducer, the dry cloth is used to wipe the side of the socket and the outside of the socket. When the surface is sticky, the acetone must be wiped off with acetone, and the following points should be paid attention to:

1, control caliber: DIN standard, 3A/IDF standard, ISO standard;

2, international industrial standards: DIN, ISO, SMS, 3A, IDF and so on;

3, product materials: stainless steel 304, 316, 316L;

4, quality and use: large and small head internal and external polishing equipment processing, to achieve surface precision requirements; this product is suitable for dairy, beverage, pharmaceutical, cosmetics and other industrial fields;

5, external processing: according to user requirements to map, sample processing non-standard products;

6, connection mode: clamp type, welding type, screw type.

ISO quality alloy steel pipe diameter should be consistent with current national standard "steel butt welding seamless pipe fittings" provisions of GB/T 12459-2005, different diameter pipe roundness should not be greater than the corresponding diameter 1%, and allowable deviation of 3mm; the size of the deviation should be allowed to meet the provisions of table 4.2.2-3 of different diameter pipe.
