Seamless Steel Pipe

 Project Location: Australia Product: Flange Specification: DN200 CLASS600 Standard & Grade:ASTM A105 Usage: slurry transmission project Received the inquiry in Dec 2022. Signed the contract in Jan 2023 Shipped time: From Jan- Feb, 2023 Arrival time: Mid Feb, 2023 At the End of Dec in 2022, Xinyue received an enquiry of 20tons Flanges from our regular client for mining slurry transmission project in Australia. The customer requires all flanges to arrive at destination within one month, and these flanges are not common pressure thickness. Therefore, we don’t have any available stocks and need to book the special customized mould. In order to meet customer needs, Xinyue Steel immediately contacted with the production department to prepare raw materials in advance, and book the mould, and according to customer requirements to contact with our air freight forwarder, reserving good shipping space in advance. Since the Spring Festival was approaching, the production capacity and air ...

    The manufacturing process of flange mainly is divided into forging, casting, cutting and rolling.     The casting and forging flanges have advantages that the blanks of them have accurate shape, size and low costs and only need simple process. But forging flanges have manufacturing defects such as blowholes, cracks, etc and have not very smooth internal organization streamline. The obvious advantages of forging flanges are that they can be forged in various shapes and they have low costs.     Forging flanges generally have lower carbon content than the casting flanges and are not easy to rust. They have smooth streamline, uniform internal organization, and better mechanical performance than that of casting flanges. There are no defects, such as blowholes and cracks existing in the casting flanges. Forging flanges are able to withstand higher shear and drawing forces than casting flanges. However, if adopting improper forging process, it will also ca...

　　A flanged joint is a connection between a pipe and another piping equipment (example, another length of pipe, a valve, or a pressure vessel). Hundreds, even thousands, of flanged joints are necessary for a piping system to function. 　　The three main components of a flanged joint are: 　　two mating flanges (the “main” and the “companion” flange). 　　a number of stud bolts for flanges (flanges of different diameter, class, and face finish require different numbers and sizes of stud bolts and nuts for proper sealing); 　　two gaskets, which can be either metallic (spiral wound, ring joint, jacketed and Kammprofile), or non-metallic (non-asbestos gaskets). 　　A steel pipe can be welded on the flange (this is the case of weld neck, socket weld, slip-on, and lap joint flange) or screwed onto it (threaded flange). Welded connections between pipes and flanges are used for high pressures and temperatures applications, and diameters above 2 inches. Threaded connections are used for small...

　　Reducing flanges are designed for when there is a change in the pipe size. The predominate flange (dimensions) matching the larger pipe size (NPT) but having a smaller bore matching the smaller pipe size (NPT). These flanges normally come in blind, slip-on, threaded and weld neck flanges. They are available in all pressure classes and provide a good alternative to connecting two different sizes of pipe. This type of flange should not be used if an abrupt transition would create unwanted turbulence, such as at a pump. 　　A reducing flange consists of a flange with one specified diameter having a bore of a different and smaller, diameter. Except for the bore and hub dimensions, the flange will have dimensions of the larger pipe size. 　　Material of Reducing Flange: 　　Cabon steel: A105, A350 LF2 　　Stainless steel: A182 F304/F304L/F316/F316L/F321 　　Alloy steel: F11, F12

　　The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face. This radius is necessary to have the flange accommodate a lap joint stub end. Normally, a lap joint flange and a lap joint stub end are mated together is an assembly system. 　　Specifications of Lap Joint Flange: 　　Standards: ANSI, MSS, API, AWWA, DIN, JIS, BS and GB. 　　Process: free forging, plate cutting. 　　Sizes range: 1/2" to 64" (and much larger size according to customers' demands). 　　Materials: Carbon steel, stainless steel and alloy steel. 　　Printing: Carbon steel and alloy steel with yellow print, black print, oil or zinc. 　　Packing: in wooden cases, wooden pallets or as per customers' special requirement, Standard Export Package. 　　 Check www.tjxysteel.com for more info
