Flanges Manufacturing Process

The Flanges Manufacturing Process is mainly divided into forging, casting, cutting and rolling.

Casting flange is a generally used flange technology, which has the advantages of high production efficiency and low production cost, and is vey suitable for medium and low pressure pipelines.

The casting flange is made of iron filings. After the iron is melted, the molten iron is poured into the mold, cooled, and processed. In Some procedures are to pour the molten iron into the mold and heat it in the forging after molding.

Cutting process is a process refers to manufacturing flanges by cutting stripes from the middle plate and then rolling them into round shape. This Cutting process is mainly used for the manufacturing of large flange. After all other processes and rolling process, weld and then compress the round shape, and finally process the serrated spiral finish and bolt hole.

Understanding Clients requirement and ensuring to supply as per these requirements is realized with the help of quality assurance at Steel Flange Mfg one of the best Stainless Steel Flanges Manufacturers in India, our product range include all types of flanges such as MS Flange ( Mild Steel ) , Raised face flange , Ring Type Joint Flanges, Weld neck flange and Flanges according to clients requirement.

Our industrial process is extremely experienced and is divided into various departments managed by knowledgeable industry specialists. We use only best quality raw materials that are obtain from only well-known and consistent businessperson. We have accept demanding quality control practices and procedures to guarantee the manufacture of only best quality products matching industry standards and parameters.

Our latest machining and gathering processes have a comprehensive line of metal removal equipment including grinding, polishing, turning, boring, milling, drilling, welding and have testing apparatus to manufacture Stainless Steel Flanges & pipe fittings. The facility also include all the required equipment to support and handle these processes as well as work holding and cutting tool requirements.

Raw Material

At the very first process, the system controls check the quality of supplies raw materials as per the test certificate and also visual and dimension. Stainless Steel Flanges are of best quality that ensures high durability, strength and resistivity to varied non-supporting conditions.

Material Inspection

Incoming quality control (IQC) is the process of observes the quality of materials and parts for manufacturing a product before production starts. With incoming inspection, you can control & check chemical analysis for quality even before leading a first item inspection or a during production inspection.

Material Cutting

In this process refers to manufacturing flanges by cutting stripes from the middle plate and then rolling them into round shape. After all other processes and rolling process, weld and then compress the round shape, and finally process the serrated spiral finish and bolt hole. We do Weight Measuring, checking cut surfaces and marking.

Flange Forging

Forged flanges generally have lower carbon content than cast flanges and are less disposed to rust. In Forgings Material Grade Check, weight measuring, and control the temperature. The forged flange is that the inner structure is unfluctuating, and there are no defects such as holes and presences in the casting.

Heat Treatment

In this process of heat treatment, the overall forging cooling speed is the slowest, the standardizing cooling speed is quicker, reducing cooling speed is faster. Flanges are mutually connected and continuous in the process. In this process also do Solution Treatment and Mechanical Testing.

Forging Rolling

It is a forging method that utilizes opposing rolls to shape a metal part. Roll forging uses rolls in order to achieve the deformation of the material, it is mainly classified as a metal forging process and not a rolling process. The forging structure of the rolls used to forge metal parts is only current over a portion of the roll's edge.

Final Inspection

In this method measure & inspect the dimension & size of the flange. The diameter is check to control what size pipe a flanges can be used with, so you must find this information by using the inside of the flange as different to the outside. We also perform some visual testing and Nondestructive testing for betterment.

Rust Prevention

The standard rust prevention treatment for stainless steel flanges include yellow (Golden) paint Coating, black paint coating / black phosphating treatment, varnish paint coating, electro galvanizing coating (Cold), varnish antirust oil coating, hot dip galvanizing coating etc. Also Marking on the flanges.

Well Packing

Steel Flanges must be packed with seaworthy packing method then delivery to clients, generally the packing way include wooden box, iron & steel cage, wooden pallet, iron & steel pallet etc. Because of the normal wooden boxes or pallets have to do fumigation treatment, we generally use plywood pallet or plywood case or box to pack SS flanges without fumigation treatment.
