ANSI 150LB RF/FF American standard Flanges are made of high-quality steel through high-pressure equipment forging, steel plate cutting or intermediate frequency furnace heating and casting. .Mechanical properties, material properties and impact resistance meet the requirements of medium and low pressure pipelines. Especially ANSI 150LB RF/FF carbon steel cast flanges, because of their low cost, are very suitable for low-pressure pipeline engineering, temporary pipeline laying, pipeline connection in deserts, and sparsely populated areas. They are very popular in the Middle East and are widely used. It is an indispensable accessory for low-pressure pipeline engineering, temporary pipeline laying, and pipeline systems in sparsely populated areas.
ANSI 150LB RF/FF American standard Carbon Steel Flanges are widely used in general industrial drainage, municipal pipeline sewage, civil pipeline drainage, other medium and low pressure pipeline systems, and air conditioning pipeline systems. It is a main accessory that connects pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Greatly reduces engineering costs.
ANSI 150LB RF/FF 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 150LB RF/FF American standard carbon Steel Flange is the most widely used and most important pipe fittings in medium and low pressure piping systems and equipment such as machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding, etc. In actual use, most of them are cast or steel plate flanges.
Our ANSI 150LB RF/FF American 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 ANSI 150LB RF/FF American Standard Carbon Steel Flanges:
According to the model can be divided into: slip-on, FACE FLAT THREADED
According to the pressure can be divided into: 150lbs,
According to the process, it can be divided into: forging flange, steel plate flange, casting flange,
According to the material can be divided into: carbon steel flange,
ANSI 150LB RF/FF American standard 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 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: Steel plate flange
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 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 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) 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.
