We have strong technical strength and can customize various flange blanks according to customer needs.Stamping thicknesses of 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 25mm, 30mm. Stamping diameter: 100mm-500mm, material: carbon steel,Generally speaking, flat welding ring loose flange is used in one of the following three situations:
1. Save costs. When the material of the pipe is special and expensive, the cost of welding flanges of the same material is high.
2. Not convenient for welding or processing, or requiring high strength. Such as plastic pipes, fiberglass pipes, etc.
3. Easy to construct. If it is difficult to align the flange bolt holes during connection or to prevent changes in the flange bolt holes during future equipment replacement.All products can be produced using American standards such as ASME (ANSI), German standards (DIN), Japanese standards (JIS), as well as national standards such as GB, JB, SH, HG, etc. Non standard products of various materials and specifications can also be customized according to customer requirements. The company is a large-scale circulation enterprise specializing in the production of flanges, automotive parts, and special-shaped stamped parts, with a combination of group, scale, flexibility, and systematization. Over the years, with scientific production processes, strict quality management, good service concepts, and reasonable sales prices, we have won a good reputation among a large number of users at home and abroad. Our products are exported to countries and regions such as the United States, Germany, Hong Kong, Australia, Southeast Asia, and Africa. Our company does not rest during holidays and is available 24 hours a day to serve you.

A flange joint consists of a pair of flanges, a gasket, and several bolts and nuts. Place the gasket on both sidesFlange sealing surfaceAfter tightening the nut, deformation occurs on the surface of the gasket when the specific pressure reaches a certain value, and the uneven areas on the sealing surface are filled to ensure a tight and leak free connection. Flange connection is a detachable connection. According to the connected components, it can be divided into container flanges and pipe flanges. Divided by structural type, there areIntegral flange, loose flange andThreaded flange.

Flange blank
Flange blank is a production object made according to the required shape, process dimensions, etc. of the finished flange for further processing.
Production process: professional overall forging, forging manufacturing, medium plate cutting, medium plate rolling, etc⑴. Reasonable mold design. In the progressive die, the arrangement of cutting sequence may affect the accuracy of stamping part forming. For the cutting of small parts of stamped parts, a larger area of punching cutting is usually arranged first, followed by a smaller area of punching cutting to reduce the impact of punching force on the forming of stamped parts.
⑵. Press down on the material. Overcoming the traditional mold design structure, a material gap is opened on the discharge plate (i.e. when the mold is closed, the material can be compressed). For key forming parts, the discharge plate must be made into an embedded structure to facilitate the solution of grinding (pressure) damage caused by long-term stamping at the pressing part of the discharge plate, which cannot compress the material.
⑶. Add strong pressure function. Thicken the size of the unloading insert pressing part (normal unloading insert thickness H+0.03mm) to increase the pressure on the material on the concave die side, thereby suppressing the flipping and twisting deformation of the stamped part during punching.
⑷. Trim a sloping or curved surface at the end of the convex die blade. This is an effective method to reduce punching force. Reducing the buffer cutting force can alleviate the tensile force on the material on the concave die side, thereby achieving the effect of suppressing the flipping and twisting of stamped parts.
⑸. In daily mold production, attention should be paid to maintaining the sharpness of the cutting edges of the convex and concave molds. When the cutting edge wears out, the tensile stress on the material will increase, leading to an increased tendency for the stamped part to flip and twist.
⑹. Unreasonable or uneven punching gaps are also reasons for the flipping and twisting of stamped parts, which need to be overcome.

The integral flange belongs to the flange standard system of the Ministry of Chemical Industry and is one of the manifestations of the flange (also known as HG flange) of the Ministry of Chemical Industry. Integral flange, also known as long diameter flange, is the English name for integral flange. In various domestic standards, IF is used to refer to integral flanges, which are flanges with a conical section neck.
The integral flange is a component that connects pipes to each other, connected to the pipe end. There are holes on the overall flange, and bolts tightly connect the two flanges. Seal the flanges with gaskets.
Integral flanges are commonly used in high-pressure pipelines, usually with raised surfaces (RF). If used in flammable, explosive, highly hazardous conditions, sealing surfaces other than RF surfaces such as raised and recessed surfaces (MFM) and mortise and tenon surfaces (TG) can be selected. Flat welding flange, plate flat welding flange, and flat plate flange are all collectively referred to, sometimes also called flat plates for convenience. This item is included in standards such as the Ministry of Chemical Industry flange, national standard flange, Ministry of Machinery flange, Japanese standard flange, German standard flange, American standard flange, and marine flange. The usage on general pipelines in the domestic industry is high, with pressures ranging from 0.25MPa to 4.0MPa.

Flat welding flange, as the name suggests, is a flange without a neck. Insert the pipe directly into the flange for welding. Generally, the inner diameter of a small-diameter flange is slightly larger than that of the pipe by 1-1.5mm, leaving a margin for appropriate adjustments during installation. There are still many large-diameter flanges left, because the flange diameter is too large, and leaving it too small is inconvenient.

The sealing surface of a flat welding flange is generally divided into two types: one is called the FF surface, which is a fully flat flange. To put it simply, this flange is like a disk with holes in the middle and corresponding bolt holes around it, which is called a fully flat flange.

There is another type that has a sealed step, in layman's terms, it is a platform that comes out of the flange, called a water line platform. Then use a lathe to draw two to three water lines on top, which is called a flat protruding flange. This water line serves a sealing function. The sealing gasket is placed between the two flange plates and secured with bolts to achieve the sealing effect
