ASTM A234 WPB reducers carbon steel fitting

ANSI B16.9 SCH40 STD carbon steel head is made of high-quality carbon steel round pipe, which is a widely used pipe fitting in carbon steel pipe fittings. ANSI B16.9 SCH40 STD carbon steel size head is made by cutting the steel pipe into pipe sections according to the requirements, putting it into the intermediate frequency pushing furnace, and heating and pushing.
. ANSI B16.9 SCH40 STD size head is used for connection between pipes of two different diameters. According to the different shapes, it is divided into two types: concentric size heads and eccentric size heads. Concentric means that the center points of the circles at both ends of the tube are on the same straight line, which is called the concentric head, and vice versa, the eccentric head. The size head is also called the reducer and the reducer.
  When using, according to construction requirements 1: Weld the elbow directly with the pipe. 2: Weld the Flanges on both ends of the elbow evenly, and connect them with Bolts to make the whole pipeline integrated and start working normally.
   ANSI B16.9 SCH40 STD carbon steel head has a wide range of uses, and is widely used in water, beverage, beer, food, petrochemical, nuclear power, machinery, medical equipment, fertilizer, shipbuilding, waterproofing and other pipeline systems. It is widely used in the pipeline system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding, air conditioning and other departments.
Types of ANSI B16.9 SCH40 STD Carbon Steel Size Heads:
According to the standard can be divided into: ANSI B16.9 SCH40 STD
According to the pressure, it can be divided into: STD, Sch40,
According to the shape can be divided into: concentric size head, eccentric size head
According to the process, it can be divided into: pushing, pressing, forging,
According to the material can be divided into: ASTM/ASME A234 WPB, WPC
According to its radius of curvature, it can be divided into long radius elbow and short radius elbow. The long radius elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, that is, R=1.5D; the short radius elbow refers to that its radius of curvature is equal to the outer diameter of the pipe, that is, R=1.0D. (D is the diameter of the elbow, and R is the radius of curvature).

Production Process of ANSI B16.9 SCH40 STD Carbon Steel Big and Small Heads
1: Cut the high-quality steel pipe into segments by sawing machine according to the product requirements, place it on the pushing machine, heat it in the intermediate frequency furnace, push it into molding, and put the formed elbow into the pressing machine for shaping.
2: Pass the shaped elbow blank through the special CNC lathe for pipe fittings according to the drawing. Welding groove processing is performed on both ends of the elbow blank, and a certain angle is reserved, with a certain edge, and the angle and deviation range are strictly implemented in accordance with the requirements of the drawings.
3: Put the elbow blank after shaping and beveling, and put it into the shot blasting machine for shot blasting on the surface of the pipe to remove the iron oxide scale on the inner and outer surfaces.
4: The finished elbow product will be inspected according to the requirements of the drawing for the thickness and the radius of the bend.

5: Type the qualified elbow on the end face according to customer requirements, including size, steel number, batch number, and identification. And according to customer requirements, the elbows are treated with anti-rust treatment, 1: paint, 2: anti-rust oil, and then put them into wooden boxes or wooden pallets for transportation.
