Product Description
Butt Welding Reducer Introduction
Butt Welding Reducer Introduction
The pipe fittings used to connect two pipes with different diameters or different cross-sectional areas are called reducers. Therefore, reducers are also known as "size heads". Reducers can be classified into circular reducers, rectangular reducers, square reducers and rectangular connected pipes with a twisting direction, which are divided according to the shape of the pipe fittings. According to the different diameters at both ends of the pipes, pipes with different diameters are divided into reduced diameter and eccentric reduced diameter. (Circular reducers and square reducers are prone to concentric and eccentric diameters, while rectangular reducers only cause unilateral skew and bilateral skew.)

Product processing
Material selection:
Choosing the appropriate raw materials is the first step. Commonly used materials include carbon steel, stainless steel, etc. Theraw materials are cut into the required length and shape.
Hot pushing:
For elbow-type ASTM A234 butt-welded pipe fittings, hot pushing is a common forming method. The blank is heated to a certain temperature and then placed into a die for pushing.

Stamping:
The blank is placed in a die, and a press is used to apply significant pressure, causing the blank to deform into the desired pipe fitting shape

Hot pressing
Hot pressing is a processing method that involves heating the material to a certain temperature and then applying pressure.Heating increases the atomic mobility of the material, reducing its yield strength and making it easier to undergo plastic deformation.
Heat treatment :
After forming, the pipe fittings undergo heat treatment processes (such as normalizing, annealing, or quenching + tempering) to eliminate stress and improve mechanical properties and corrosion resistance.
Blank shaping:
Blank shaping is a critical step in the mechanical manufacturing process, aimed at correcting and optimizing the shape and dimensions of the blank obtained from preliminary processing.
Beveling:
Before butt welding, the welding area of the pipe fitting must undergo beveling. There are various beveling forms, such as V-type beveling and U-type beveling, selected based on the wall thickness of the pipe fitting and welding requirements.
Circularity correction:
Circularity correction is an operation that corrects the shape of circular workpieces or blanks to make them as close as possible to an ideal circle.
Surface Treatment:
Methods such as sandblasting, acid washing, or passivation are used to remove scale, rust, and impurities, thereby improving the surface quality of the pipe fittings. Sandblasting effectively removes rust, scale, oil stains, and other impurities from the metal surface. Painting pipe fittings is a surface protection process. After applying anti-rust paint, it can effectively resist atmospheric corrosion and prevent rusting of the pipe fittings.

Marking:
Marking on pipe fittings refers to the process of engraving text, numbers, or symbols on the surface of the fittings.
Inspection:
Quality inspection is an indispensable part of the stainless steel butt-welded pipe fitting manufacturing process. This step
typically includes dimensional inspection, visual inspection, weld inspection, and other aspects to ensure product quality and reliability.
Packaging:
During transportation and storage, pipe fittings may be subjected to external forces such as collisions, friction, and
compression. Proper packaging can minimize damage caused by these external forces. For stainless steel butt-welded pipe fittings, protective caps are added to both ends to prevent damage during transportation and storage. The choice of packaging materials depends on the surface requirements of the product, with common options including plastic bags, foam, bubble wrap, and woven bags.
