Con Reducer

In addition to the production of eccentric reducing pipe using steel pipe as raw material, some specifications of reducing pipe can also be produced by steel plate stamping process. The shape of the die used for drawing is designed according to the size of the reduced inner surface, and the steel plate after blanking is pressed and drawn by the die.

Production process

Product description

Introduction to reducing tube folding concept:

Eccentric reducing pipe is a kind of pipe fittings used for reducing the diameter of the pipe. The forming process is usually used for reducing the diameter, expanding the diameter or reducing the diameter and expanding the diameter, and stamping can also be used for some specifications of reducing pipe.
In addition to the production of eccentric reducing pipe using steel pipe as raw material, some specifications of reducing pipe can also be produced by steel plate stamping process. The shape of the die used for drawing is designed according to the size of the reduced inner surface, and the steel plate after blanking is pressed and drawn by the die.

Introduction of reducing tube size head:

Reducing tube is also called large and small head, reducing tube, different straight through. Any of several chemical pipe fittings used to connect two pipes of different diameters. According to the different shape, it can be divided into concentric large and small head and eccentric large and small head. Size head material includes stainless steel size head, alloy steel, carbon steel size head, size head material is 20 steel, Q235, Q345, 16Mn and so on.

Seamless size head making

A reducer is a pipe fitting used for pipe calibers. The commonly used forming process is reducing pressing, expanding pressing or reducing plus expanding pressing, and stamping can also be used for some specifications of reducing tubes.

Size head reduction/expansion forming:

The process of reducing the size of the head is to put the tube blank with the same diameter as the big end of the head into the forming die. By pressing the tube blank along the axial direction, the metal moves along the die cavity and shrinks to form. According to the size of the reducing tube, it can be divided into one pressing forming or multiple pressing forming.

Large and small head stamping forming:

In addition to using steel pipe as raw material to produce the size of the head, some specifications of the size of the head can also be produced by steel stamping process. 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 pressed and drawn by the die.

Before the size of the head bonding, use a dry cloth to wipe the side of the socket and the outside of the socket. When there is oil on the surface, use acetone to wipe it clean. There are the following points to note:

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 to meet the requirements of surface precision; This product is suitable for dairy, food, beer, beverage, pharmaceutical, cosmetics and other industrial fields;

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

6, connection: clamp (quick) type, welding type, thread (loose) type.

Pay attention to the size of the head is also suitable for pipe diameter reduction in the environmental dust removal industry, generally made of steel plate rolling cutting and welding, pipe diameter size is different, material

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

The size of the head is divided by material:

Carbon steel: ASTM/ASME A234 WPB, WPC

Alloy: ASTM/ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP911, 15Mo3 15CrMoV, 35CrMoV

Stainless Steel :ASTM/ASME A403 WP 304-304L-304H-304LN-304N

ASTM/ASME A403 WP 316-316L-316H-316LN-316N-316Ti

ASTM/ASME A403 WP 321-321H ASTM/ASME A403 WP 347-347H

Low temperature steel :ASTM/ASME A402 WPL3-WPL 6

High performance steel: ASTM/ASME A860 WPHY 42-46-52-60-65-70

Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon plating, PVC, PPR, RFPP(reinforced polypropylene), etc.

The size of the head is divided by production method:

Can be divided into push system, pressing, forging, casting and so on.

The size of the head is divided by manufacturing standards:

It can be divided into national standard, electrical standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
