ANSI A105 American standard carbon Steel Flange is made of high-quality A105 (20Mn) material. It is made of billet blanking, heating, high-pressure equipment forging or selecting high-quality scrap steel and heated by intermediate frequency circuit. Some of them are subjected to annealing heat treatment according to customer requirements. , It is a necessary accessory in the pipeline system of oil field, refinery, chemical plant and heavy industrial enterprise, especially, because it can withstand high pressure, it is widely used in industrial pipelines and low, medium and high pressure pipeline systems.
ANSI A105 American Standard Flange is a detachable connection. It is to fix two pipes, pipe fittings or equipment on a flange plate, and between the two flange plates, add a flange gasket and fasten them together with Bolts to complete the connection. American standard flange connection is an important connection method for pipeline construction.
During construction and use, the American standard Carbon Steel Flanges are evenly welded at both ends of the pipeline, and then fastened with bolts to effectively connect the pipelines, Valves, pumps and other equipment accessories, so that the entire pipeline is integrated and starts to work normally. .
ANSI A105 Flanges are the most widely used and most important pipe fittings in medium and high pressure piping systems and equipment such as machinery, petroleum, chemical industry, water conservancy, electric power, and shipbuilding.
Our ANSI A105 carbon steel flanges are standardized in material, 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 ANSI A105 Carbon Steel Flanges:
According to the model can be divided into: slip-on, Welding Neck, THREAD FLANGES Socket
weld ,Blind flanges ANSI FF
According to the pressure can be divided into: 150lbs, 300lbs, 600lbs, 900lbs, 1500lbs, 2500lbs.
According to the process, it can be divided into: forging flange, casting flange,
According to the material can be divided into: carbon steel flange, stainless steel flange, alloy steel flange
1) Ansi A105 Flange production process:
a: Forged flange
Saw billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat them to 1000 degrees to take out, and then forge the flange blanks into ring flanges through forging machines such as forging presses and air hammers.
b: cast flange
Put the standard scrap of low carbon steel into the intermediate frequency furnace and heat it to 1200-1500, then pour it into the mold to form the ring flange blank.
2) The forged 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) The flanges that have passed the inspection will be typed on the end face of the flange according to the customer's requirements, and the flange will be anti-rust treatment according to the customer's requirements, 1: black anti-rust paint, 2: anti-rust oil, 3: galvanized, Then put into wooden boxes for shipping.
