Supply S30408 stainless steel reducer professional manufacturers

Reducing pipeis a type of pipe fitting used for pipe diameter. Forming process is usually used for reducing size pressing, expanding size pressing or reducing size plus expanding size pressing, for some specifications of reducing pipe can also be used stamping forming.

1.Reducing/expanding forming

The size of the head reducing forming process is the size of the head and the large end of the same diameter of the tube billet into the forming die, through the axial direction of the tube billet pressing, the metal along the cavity movement and shrinkage forming. According to the size of reducing pipe, it can be divided into one pressing forming or multiple pressing forming.

2.Stamping

In addition to the use of steel pipe as raw material for the production of the size of the head, part of the size of the head can also be used for steel sheet stamping process production. The shape of the drawing die is designed according to the size of the inner surface of the head, and the steel plate after blanking and drawing is formed with the die.

Before bonding the large and small heads, wipe the socket side and the outer side of the socket with a dry cloth. When the surface is oily, wipe it clean with acetone. The following points should be noted:

1, control diameter: DIN standard (DN10-6), 3 a/IDF criteria (1/2 "to 6"), ISO standard (12.7-152.4 Ф Ф);

2, International industrial standards :DIN, ISO, SMS, 3A, IDF, etc.

3, Product material: stainless steel 304, 316, 316L;

4, quality and use: the size of the head inside and outside with high-grade polishing equipment processing, to meet the requirements of surface precision; This product is suitable for dairy products, food, beer, beverage, pharmaceutical, cosmetics and other industrial fields;

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

6, connection mode: clamp (quick installation) type, welding type, thread (live connection) type.

Note that the size head is also suitable for pipe diameter reduction in environmental dust removal industry. Generally, it is made of steel plate rolling, cutting and welding. The pipe diameter is different in size and material

Generally are hot rolled coil, the application is very good, can save costs.

Characteristics of stress distribution

The bending moment caused by the area pressure difference between the big end and the small end of the reducing pipe causes the phenomenon that the big end is relatively open and the small end is relatively contracted.
