Flange manufacturing Process
Process of Manufacturing
Our industrial process is extremely sophisticated and is divided into several departments managed by knowledgeable industry specialists. We use only quality raw materials that are procured from only well-known and consistent vendors. We have adopted demanding quality control practices and procedures to guarantee the manufacture of only quality products matching industry standards and parameters.
Necessities are effective for normal situation, in special you have to contact us to introduce. Our machining and gathering processes have a comprehensive line of metal removal equipment including turning, boring, milling, drilling, grinding, polishing, welding and have testing apparatus to manufacture forged fittings and pipe fittings. This facility also comprises all the required equipment to support these processes as well as work holding and cutting tool requirements.
Raw Material
Beginning with this process, the system controls the quality of all external supplies as per the raw material test certificate of the material. Stainless Steel Flanges (SS) are of premium quality that ensures high durability, strength and resistivity to varied non-supporting conditions.
Material Inspection
Incoming quality control (IQC) is the process of monitoring the quality of materials and parts for manufacturing a product before production starts. With incoming inspection, you can control for quality even before leading a first item inspection or a during production inspection.
Material Cutting
On the central plate, the disk with the internal diameter and the internal diameter of the flange with the processing amount is straight cut out, and the bolt hole and the water line are processed. The flange thus produced is called a cut flange, and the extreme diameter of such a flange is limited to the width of the central plate.
Flange Forging
Forged flanges usually have lower carbon content than cast flanges and are less disposed to rust. Forgings have better streamlined shape, thicker structure and better mechanical properties. The forged flange is that the inner structure is uniform, and there are no harmful defects such as holes and presences in the casting.
Heat Treatment
The flange is in the process of heat treatment, the overall forging cooling speed is the slowest, the standardizing cooling speed is quicker, reducing cooling speed is faster. Flange are mutually connected and continuous in the process. Coating or packaging methods can protect heating molten salts and in vacuum.
Forging Rolling
Roll forging is a forging method that utilizes opposing rolls to shape a metal part. Even though roll forging uses rolls in order to achieve the deformation of the material, it is classified as a metal forging process and not a rolling process. The forging geometry of the rolls used to forge metal parts is only current over a portion of the roll's edge.
Final Inspection
Place one end of a tape measure on the inside of the flange. The diameter is used to control what size pipe a flange can be used with, so you must find this information by using the inside of the flange as different to the outside. Stretch your tape measure across the center of the circular shape of the flange until it touches the other side of the unit.
Rust Prevention
The standard rust prevention treatment for steel flanges include yellow (Golden) paint Coating, black paint coating or black phosphating treatment, varnish paint coating, varnish antirust oil coating, electro galvanizing coating (Cold), hot dip galvanizing coating etc.
Well Packing
Steel flanges must be packed with seaworthy packing method then delivery to customers, usually the packing way include wooden box, wooden pallet, iron & steel cage, iron & steel pallet etc. Because of the normal wooden boxes or wooden pallets have to do fumigation treatment, we usually use plywood pallet or plywood case or box to pack steel flanges without fumigation treatment.
