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: Are flanges and flanges a kind of thing?: It's a thing. The flange is just one piece. I'm engineering myself, or a flange.

Q: What does "flange connection" mean?: Flange connection is the pipe connection, both ends are welded flange plate, bolt fastening, is a way of pipe connection.

Q: What do DN and PN stand for on the flange?: Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).Nominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.DN is nominal diameter, nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of universal caliber. The pipes of the same nominal diameter can be connected with each other and are interchangeable. It is not the outer diameter or inner diameter of the pipe in actual sense, although its value is close to or equal to the diameter of the pipe.PN nominal pressure.DefinitionRelating to the mechanical and dimensional characteristics of the components of the piping system and the identification of letters and combinations of numbers for reference. It consists of letters PN and followed by dimensionless numbers.Note 1: numbers followed by letters "PN" do not represent measurements and are not used for purposes of calculation unless otherwise specified in the relevant standards.Note 2: is not associated with the relevant pipe component standards, but the term "PN" does not make sense.Note the 3: piping element allows the pressure to depend on the PN value of the element, the material and design, and allows the operating temperature, etc., to allow the pressure to be given in the corresponding standard pressure temperature class table.Note 4: all pipe elements with the same PN and DN values shall have the same mating dimensions as their flanges.

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: How many kilograms is WN300-1500M in the flange standard?: The kilogram (symbol Kg) is the basic unit of measurement in the international system of units, and the kilogram is one of the most common basic units used in everyday life. A kilogram is defined as the quality of an international kilogram of raw materials, almost as much as a liter of water. The kilogram is the only one with Si prefixes of the basic unit, and the only one still use manual products for the definition of international units (units with other basic physical properties are defined, in order to replicate in different laboratories).

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: Can the hole on the flange be threaded?: The flange bolt hole can tap out the internal thread.But I haven't seen it. There is no flange piece to do so, the direct bolt nut connection is convenient.

Q: I've heard that the ultra short flange distance can help micro transfer more lenses. What's the principle? Why is the long distance SLR not the advantage? What does the flange distance decide?: The average flange distance refers to the distance between the metal ring on the camera body and the lens, which is in contact with the lens, to the imaging medium (photosensitive element or negative plate),This distance is longer, plus the transfer ring is longer, the focus is not easy, to the imaging medium, that is, with the transfer ring, can not focus.And the distance between the flanges is short, and the adapter ring will not be too long.

Q: What do you mean by "RF", "A" or "B" in the flange?: That is to say, the size of the outer diameter of the pipe

Q: In the pipe installation, the three way, the elbow, the big head and the flange do not need the quota?: In industrial pipe installation, three - way, elbow and big head should be calculated separately.
