jis b2311 SGP carbon steel pipe fitting reducer

Jis b2311 sgp carbon steel size head
The carbon steel head is made of high-quality carbon steel round pipe, which is a widely used pipe fitting in carbon steel pipe fittings. SGP is the material grade of Japanese standard carbon steel pipe. Jis b2311 sgp carbon steel 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 it.
. 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.
   Jis b2311 sgp 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.
Our JIS B2311SGP carbon steel pipe fittings with large and small heads are standardized in materials, finely processed and priced in line with market demand. According to the needs of different markets and different customers, special stereotyped manufacturing can fully meet the requirements of customers and markets for different uses. And we will inform customers of market needs so that they can quickly expand the market.

The production process of JIS B2311SGP carbon steel big and small heads
1: Cut the SGP 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.
