JIS B2311S GP elbow carbon steel fittings

JIS B2311SGP elbow is one of the most widely used pipe fittings in carbon steel pipe fittings. SGP is the material grade of Japanese standard carbon steel pipe. JIS B2311 SGP elbow 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.
The main function of the JIS B2311SGP elbow is to combine with the steel pipe or flange at the turning point of the pipeline system to connect two pipes of nominal diameter, so that the pipe can be turned at 90°, 45°, 180° and various degrees. Change the direction of the pipe. The nominal pressure is 1-1.6Mpa.
Due to the good comprehensive performance of JIS B2311SGP elbows, carbon steel elbows are widely used, and are widely used in pipeline systems such as water, beverages, beer, food, petrochemicals, nuclear power, machinery, medical equipment, fertilizers, shipbuilding, and waterproofing. Elbow can be divided into 15, 30 45 60 90 180 points according to the angle, of which 45°, 90°, 180° are the most commonly used,
    When using, according to the construction requirements, at the bend of the pipeline 1: Directly weld the elbow to the pipeline. 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 B2311SGP elbow is the most widely used pipe fittings in basic engineering piping systems and equipment such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding and other basic engineering.
Our JIS B2311SGP elbow carbon steel pipe fittings are standardized in materials, finely processed, and priced in line with market demand. According to the needs of different markets and different customers, special shaped manufacturing can fully meet the requirements of customers and markets for different flanges. And we will inform customers of market needs so that they can quickly expand the market.
Types of JIS B2311SGP elbows:
According to the standard can be divided into: JISB2311 SGP
According to the pressure, it can be divided into: Sch10, Sch20, Sch30, STD, Sch40, XS; Sch80, XXS
According to the process, it can be divided into: pushing, pressing, forging,
According to the material can be divided into: ASTM/ASME A234 WPB Q235, 20#, 16Mn, Q345B
According to its radius of curvature, it can be divided into long radius elbow and short radius elbow.
Production process of JIS B2311SGP carbon steel elbow
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.
