SGP Carbon Steel Pipe Fittings End Weld Cap

SGPB2311 carbon steel head (pipe cap), also known as plug, cap, pipe cover, bulkhead, used to close the pipeline, the function is the same as the flange blind plate, but the cap can be directly welded on the pipe, no need to Other fittings fit. The cap includes the design of convex cap, conical shell, reducing section, flat cover and shrinking mouth.
Convex caps include: hemispherical caps, elliptical caps, disc caps and spherical caps. Among them, the oval cap has the most uses and is the most widely used.
SGPB2311 carbon steel pipe caps are widely used in: water, beverage, beer, food, petrochemical, nuclear power, machinery, medical equipment, fertilizer, shipbuilding, waterproofing and other pipeline systems.
When using, according to the construction requirements, directly weld the pipe cap with the pipe at the top of the pipe, so that the whole pipe is integrated and starts to work normally.
Pipe caps are an indispensable part of pressure vessel equipment in many industries from petrochemical, atomic energy to food and pharmaceutical industries. The cap is also the end cap on the pressure vessel and is a main pressure-bearing component of the pressure vessel. The quality of the cap is directly related to the long-term safe and reliable operation of the pressure vessel.
Our JIS B2311 carbon steel pipe caps 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.
Types of JIS B2311SGP Carbon Steel Pipe Caps:
According to the standard can be divided into: JISB2311 SGP
According to thickness, the pressure 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
SGPJIS B2311 carbon steel pipe cap production process:
1: Cut the high-quality steel plate into blocks by sawing machine according to the product requirements. After heating, put it into the press for extrusion.
2: The formed pipe cap blank is passed through the special CNC lathe for pipe fittings according to the drawing. Welding groove processing is performed on the end of the tube cap 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 pipe fitting blank after shaping and beveling, and put it into the shot blasting machine for shot blasting on the surface of the pipe fitting to remove the iron oxide scale on the inner and outer surfaces.
1: Put the high-quality steel plate with the required raw materials, put it into the intermediate frequency furnace for heating, and then place it
   On the mold, it is backlogged by a press,
2: Shape the formed tube cap blank, shape, sandblast. Remove the iron oxide scale on the inner and outer surfaces
3: The formed pipe cap blank is passed through the special CNC lathe for pipe fittings according to the drawing. Welding groove processing is performed on the end of the tube cap 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.
4: The finished pipe cap is inspected according to the requirements of the drawing for the thickness, the radius of the flexures and the aperture.

5: Type the qualified pipe caps on the end face according to the customer's requirements, and do anti-rust treatment to the pipe caps according to the customer's requirements, 1: paint, 2: anti-rust oil, and then put them into wooden boxes or wooden pallets for waiting transport.
