JIS B2220 Carbon Steel Flanges/Oil Pipeline Flanges

JIS carbon Steel Flange is the most widely used flange in the world. JIS flange standard is one of the earliest flange standards in the world. JIS and DIN flange standards and BS4504 flange standards are simultaneously adopted by the market. JIS5K JIS10K pressure Flanges are the most conventional, the most popular, and are commonly used.
   JIS Carbon Steel Flanges are a kind of pipe fittings that connect pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
   During construction and use, the JIS carbon steel flange is welded evenly at both ends of the pipeline with high-quality welding rods, and then fastened with Bolts to effectively connect pipelines, valves, pumps and other equipment accessories, so that the entire pipeline is integrated, and the normal work.
   It is the most widely used pipe fittings in the pipeline system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding and other departments.
   Our JIS standard carbon steel flange material specification, fine processing, the price meets the 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 carbon steel flanges:
According to the model can be divided into: JIS SOP, JIS SOH JIS Blind
According to the shape, it can be divided into: FF flange, RF flange, Welding Neck flanges
According to the pressure can be divided into: JIS 5K JIS 10K JIS 16K JIS 20K JIS 30K
According to the process, it can be divided into: forged flange, cast flange, steel plate flange
According to the material can be divided into: carbon steel flange, stainless steel flange, alloy steel flange
DIN carbon steel flange production process:
1) a: Forged flange
Saw billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat to 1000 degrees to take out, and then forge the flange blanks into ring flanges by forging machines such as forging presses and air hammers, b: steel plate flanges
Put the steel plate into the punching machine, put it into the corresponding mold, and directly punch it into a ring flange blank.
c: cast flange
Put the low carbon steel standard scrap into the intermediate frequency furnace and heat it to 1200-1500, pour it into the mold
The type is a ring flange blank.
2) The formed ring flange blank is processed into a ring flange on a CNC machine tool according to the drawing, and then the flange is drilled with a CNC drilling machine according to the drawing requirements, and the finished product is completed.
3) For the finished flange product, the thickness, hole diameter, center distance, inner and outer diameter of the flange shall be inspected according to the drawing requirements.

4) Type the flanges that have passed the inspection on the end face of the flange according to the customer's requirements, and do anti-rust treatment to the flange according to the customer's requirements, 1: paint, 2: anti-rust oil, 3: galvanized, and then install it. In wooden box for shipment.
