INFORMATION

Details of  The Pipe Reducer

Butt weld steel pipe reducers are pipe fittings with two ports of different diameters. They can be used to connect pipes of different diameters by welding, providing a smooth transition for fluid flow. This reduces resistance and pressure loss, and helps to maintain efficient operation of the pipeline system.
Butt weld steel pipe reducers also allow for a flexible layout of the pipeline system in a limited space, providing convenience for smooth operation and layout adjustments.

It has two types:
Concentric pipe reducer and Eccentric pipe Reducer.

Concentric butt weld reducers connect two pipes with different diameters but with coinciding center axis lines, and are suitable for smaller diameter pipe systems.
Eccentric butt weld reducers are used to connect two pipes with different diameters but with non-coincident center axes, allowing for vertical and horizontal offset of the pipes. They are suitable for situations where vertical and horizontal offset needs to be resolved or space limitations need to be avoided.

Material Grades

We manufacture and export concentric reducers in certified materials to match your connecting pipes.

  • Carbon Steel (High Demand):

               ASTM A234 WPB: The industry standard for moderate/high-temperature service. Widely used in pressure piping.

               ASTM A420 WPL6: Impact-tested carbon steel for low-temperature applications (e.g., cryogenic systems).

  • Stainless Steel:

                ASTM A403 WP304/304L: Standard corrosion resistance.

                ASTM A403 WP316/316L: Enhanced resistance to chlorides and acids.

  • Alloy Steel:

                ASTM A234 WP5, WP9, WP11, WP22, WP91: For high-pressure power generation and steam lines

 

Application:

  1. Carbon steel pipe Reducers can be used for the control of water, gas, steam, oil, and corrosive media in chemical, petroleum, metallurgy, light industry, electric power, plumbing, food, pharmaceutical, fiber, ink, and other industries.
  2. Sanitary valves, fluid fittings, special fittings of special industries, and mechanical supporting equipment can be used in dairy, pharmaceutical, beer, beverage, edible oil, and other industries to meet their professional requirements.
  3. Reducers are produced according to different standard systems which can be adapted to the corresponding standard system of supporting equipment, JS FITTINGS can produce non-standard reducers according to the requirements of users, and reducers are suitable for special purposes.

FAQ

Are you a manufacturer or trading company?
We have had true factory and manufacture costing and forged flanges since 1983, and produced pipe fittings for more than 20 years. Our factory is located in Yanshan Cangzhou City. Welcome to visit us. We are pleased to show you our advanced production lines.
Can you supply a price list of all your items?
Because the price is affected by material cost, total quantity, transportation cost, and exchange rate, a draft price list is not helpful for your purchase. Please kindly supply us with your purchase details, such as item name, type, size, pressure, surface treatment, quantity, and destination port. We will supply you with a real competitive offer.
Can your price be lower?
Of course. The thickness tolerance of the pipe fittings is ±12.5%, and the thickness tolerance of the forged flanges is ±1mm. If the bigger tolerance is acceptable for you, the price can be lower. If you need products with standard tolerance, please consider adding the quantity, the more the cheaper.
How can I confirm the quality of the first order?

1. we have been a professional manufacturer for many years and have ISO certificates.
