Hanland fitting to tell you what are common titanium pipe production process 1, weld titanium elbow titanium pipe in our country to use more early domestic titanium pipe fitting not manufacturer production standards, have to make people adopt more weld type ( Commonly known as the 'mitre type)' The processing technology of the titanium elbow, it is multifarious. Usually used to cut the tube into many segments oblique mouth and welded together or sheet metal under section into many leaf shape material, rolling welding, large amount of weld. Because of the geometry of discontinuous welds, will produce the high stress concentration, therefore, to this kind of pipe fitting job pressure and temperature must be made strict rules. Weld will greatly reduce the corrosion resistance, easy to leak, and poor appearance, inner surface for folding surface increases the pipeline transmission and back weld is serious erosion resistance and reduced life span. 2, to take on the straight path to open hole, welding tee branch pipe directly welded together, because of titanium processing performance is better than other materials, the curve of spot welding processing is also very difficult. More importantly, right Angle seam, it is a serious influence the flow conductivity of the medium, increasing the pipeline transport resistance, the curve of the curve is welding difficulties, three is the rectangular area, increasing erosion rectangular areas early losses. On 3, tabletting welded titanium pipe bend mould billet mould in order to improve the defects of weld titanium elbow, more with half a piece of welded titanium pipe bend. It compared with multiple seam 'mitre' type, weld less relevant, and no head on by the erosion of weld, and the consequent flushing, and corrosion situation is better. 4, cast type elbow people trying to get rid of weld, developed the titanium seamless elbow, the casting type elbow, though in a seamless elbow and appear, but the wall thickness ( At least 5 mm) And the pipe wall thickness ( 2 ~ 4毫米) Cannot match, and poor surface finish, and increase the transmission resistance. More importantly inside there are a lot of the casting defects such as porosity, the serious influence the corrosion resistance and life, is not suitable for the use of titanium pipe butt welding type, mostly used in the small diameter of bearing type pipe fittings, such high technology production cost of titanium pipe, not the user's identity. 5, stamping method was used to punch the titanium elbow, appearance is almost meet the standard requirements, but from the point of substance, the processing technology is to bloom on the punch in the stamping die stamping forming, molding process will bend back tension, forcing back thin, compression of abdominal wall thickening and cause uneven wall thickness or to crinkle. And in use process for elbow back to withstand erosion, due to the back wall thinning, so back produces early losses. Wall thickness is hard to guarantee, the pressure and life all can not meet the criteria for the wall thickness tolerance requirements, try not to use this process in the production of titanium elbow. 6, push the process how to improve the life of titanium pipe? Increase titanium tube life and become a big academic problems in pipeline design technology. Elbow push technology is introduced by Japan in the late of the eighty s, a new steel elbow production technology in our country. Because the process can realize continuous production, and production of the elbow wall thickness uniformity, thus it quickly replaced the traditional process. And successively developed titanium seamless tee, seamless reducer titanium seamless pipe fittings products, such as large diameter seamless pipe fittings can reach Φ 219, and reached the ASTM B363 - 95 standard requirement. Xin er, is located in the large city in the middle of * * * * * * - Entrance of wuhan city west, hanchuan textile industrial park, is one of the professional manufacturer of ductile pipe fittings and spare parts. Company's main: hanland pipe fittings, ductile iron pipe fittings, ductile cast iron, ductile iron pipes in 2004, the company invested nearly ten million yuan has introduced new factories and new levels of domestic EPS a vacuum mold production line, has formed four thousand tons scale, can provide users with in accordance with ISO2531 standard brick and various types of DN100 - various interfaces DN800mm of more than 3000 kinds of products, can also according to customer's need to produce all kinds of non-standard pipe fittings and accessories, the company integrating scientific research, production and service, may at any time to provide technical advice and on-site service. Company has all kinds of advanced testing equipment, well-equipped, advanced technology, in strict accordance with ISO9002 instruction system and Swiss SGSIS9002 quality system of organizing production, the production of ball pipes pieces, with its high strength, good toughness, excellent characteristics of high pressure resistance, corrosion resistance, with the essence of the iron pipe steel tube performance, is a traditional cast iron pipe of updated products, widely used in water, gas and liquid gas pressure conveying, now is in most provinces, the city's urban water supply, gas supply engineering has the close relationship between supply and demand, well received by users. Company commitment: to the management idea of honest credible, with 'started in user requirements, and finally customer satisfaction' for the purpose of the production and operation, in order to realize the users, enterprises, social three sides the goal of mutual benefit welcome patrons!
