Aluminum alloy flange manufacturers

    The advantage of aluminum alloy flanges is the low temperature resistance and corrosion resistance of aluminum alloy materials. They are often used in low temperature pipelines and chemical pipelines. Aluminum alloy flanges are divided into flat welding flanges (plate flat welding flanges PL), There are three types of flat welding flange with neck (SO) and butt welding flange with neck (WN). The disadvantages of aluminum alloy flanges are that they are soft and not pressure resistant, and the cost of butt welding flanges with necks is too high, so plate flat welding flanges are commonly used.

    Aluminum alloy plate flat welded flanges are suitable for aluminum alloy pipe connections with a nominal pressure not exceeding 2.5MPa. The sealing surface of plate flat welded flanges can be made full plane, Convex surface, raised surface RF, concave-convex surface, tongue-and-groove surface, plate flat welded flanges are widely used in aluminum alloy flanges, and are used in the case of relatively mild media conditions, such as central air-conditioning low-temperature and low-pressure purified air, circulating water pipes.

    According to different levels of pressure, flanges are equipped with different materials, ranging from low-pressure asbestos pads, high-pressure asbestos pads to metal pads.

    1. Divide carbon steel flanges, cast steel, alloy steel flanges, stainless steel flanges, etc. by material.

    2. According to the production method, it can be divided into forged flanges, cast flanges, welded flanges, rolled flanges (super large models)

    3. According to the manufacturing standard, it can be divided into national standard (Ministry of Chemical Industry standard, petroleum standard, electric power standard), American standard, German standard, Japanese standard, Russian standard, etc. The butt-welded ring neck loose flange connection finger consists of a pair of flanges, a gasket and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After the nut is tightened, the specific pressure on the gasket surface reaches a certain value and deforms and fills up the unevenness of the sealing surface to make the connection tight and leak-proof. Our company sells flanges of various materials, and the products meet the relevant national requirements and standards, and are of high quality. Welcome to buy!
