The main material for carbon steel, stainless steel and alloy steel, such as ASTM A105, A182, A350, A694, ST35.8, ST45.8, ST37.2, C22.8, SS400, SM400B, 20Mn, 20 #, Q235, 16Mn, F304/304L, F316/316L, F321, LF2,F11/42/46/52/60/65, 15CrMo, 12Cr1MoV such.

The production base total area is about 82,300 square meters.The annual production capacity is more than 9000 tons, with fine processing technology and advanced detection means.

The company has passed Rhine, Germany(TüV) ISO9001 quality management system certification , European pressure equipment and materials PED97/23/EC certification and German pressure equipment and materials AD2000-WO certification. It has also passed the pressure pipe components manufacturing safety registered certification of the State Quality Inspection Administration and classification societies certified .So a more effective guarantee is provided for the quality of the products.It has become the one of the enterprises firstly through the certification in the industry.It plays an important leading role in the industry.

The high-quality products are widely used in petroleum, chemical, metallurgy, electric power, ship, natural gas , pipeline industries and so on.It has won the users good evaluation.At the same time,the products are exported to Europe and the United States, the Middle East, Africa and South-East Asia regions and other countries.

Q: In the pipe connection, what are the flanges, the live flanges?: Dead welded or fixed. Live: mobile.

Q: How much screw does the flange of DN80 fit?: See their current scope of use, the basic double headed spiral 16*100.1, flange (Flange), also known as flange, flange plate or edge. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures.2. Pipe flanges refer to flanges used for piping in pipe installations. They are used on equipment to refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms. Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different.

Q: What is low pressure flange valve?: The pressure is not high, 0.6-4.0MPa, connection way for the flange connection valve, called low pressure flange valve

Q: Steel flanges (mechanical machining) can produce forgings flanges? Grades range from B to pressure piping: To have a professional qualification certificate.

Q: Must the flange height go along with the standard?: This is certain, everyone valve is standard, and if you flange is not standard, how to bolt holes on the valve ah?

Q: How are the PPR tubes and flanges bonded?: Flange (Flange), also called flange or flange plate. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe. Flange connection or flange connection, is defined by the flange, gasket and bolt connection between the three sealing structure of the detachable connection as a combination of group pipe flange refers to the pipeline installation of piping flange, used in equipment refers to equipment import and export flange. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Flange, threaded connection (wire), flange and welding flange.Flange material.In PPR pipe fittings, the flange is mainly made of PVC material. It is mainly used as the gasket flange connection of PPR pipe fittings (flange, joint). It is made up of a pair of flanges, a gasket and some bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, the tight connection. A flange connection is a detachable connection. The connecting parts can be divided into containers, flanges and tubes; in accordance with the structural type, there are integral flanges, looper flanges and threaded flanges. There is a common integral flange flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange welding flange, large rigidity, suitable for high temperature pressure

Q: Who explains the difference between the injection molded flange, the injection molded joint and the injection molded flange joint?: Plastic flange including plastic flange joints and flanges, steel flange can and plastic pipe connection, so it must be fused to steel joints transition; sleeve joints are generally for plastic pipe connection joint; flexible clamp joint is a steel tube or pipe joints of steel plastic composite.Injection molding: injection molding is an industrial product molding process. Beijing Fuhua Plastic Co., Ltd. products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding. Die casting method. Injection molding machine (referred to as the injection molding machine or injection molding machine) is plastics molding equipment of thermoplastic or thermosetting material using plastic mold made of various shapes, injection molding by injection molding machine and mold. Injection molding products are widely used in mobile phones, portable computers, various plastic casings, communications, micro motors, computers, electrical appliances, electronics, toys, clocks and watches, lamps and lanterns, locomotives and other industries.

Q: Flat plate concave convex flange has no national standards?: No national standards;A flange in the form of a concave convex surface. The pressure is generally high, while the high pressure products are welded or socket welded. Not really flat plate. However, if it is hard to do, there is no problem.But there is no national standard. We are the manufacturer of flanges.

Q: One of them is not protected and damaged when it is welded. Is this acceptable? What are the unacceptable criteria?: Acceptable. When installed, the sealing pad does not affect the use

Q: Flange valves include flanges: Flanged valve as a whole itself each end has a flange, these two flanges are included in the valve, and do not contain these two flanges matching flange, but you can spend money for you to match.

Our company has strong professional technical force, rich experience, integrated data and advanced equipment, as well as high-quality forging, machine-processing, assembling and packing production lines.
