Tianjin Pipe company with excellent products, excellent service and reasonable prices to serve our customers and our aim: "quality of survival, reputation and development." Our business philosophy: "Sincerity-oriented, customer first." Our advantage: "adequate, reasonable price", according to customer requirements, welcome new and old customers to negotiate. Professional production of high-frequency welded pipe, welded pipe. Materials commonly used in material generally Q235A, Q235B, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, 16Mn, 20 #, Q345, L245, L290, X42, X46, X70, X80 and so on. Where X42, X46, X56, X80 and other material for the API standard material, is not our common pipe materials. Those who produce longitudinally welded pipes, thermal expansion, etc., in order to strip for the production of raw materials, high-frequency welding equipment on a straight seam welding Longitudinal tubes get called. (Due to a pipe welding line hence the name). Which according to different purposes, and different post-production processes. (Can be divided into scaffolding tubes, fluid tubes, wire casing, stand pipe, tube and other types). Longitudinal standard GB/T3091-2008 and low pressure fluid pipe is welded pipe, most commonly water, gas transmission, after the welding to be a more than ordinary pipe pressure test, hence the low pressure fluid than ordinary straight seam pipe Pipe prices are generally a little higher (according to the current market price, it is probably higher than the 80 yuan) For example: welded steel fluid pipe 1 inch (DN25) (that is Φ33.5 * 3.25) price of around 4300 per tonne, while the ordinary Longitudinal in 3650 or so. Longitudinal main production processes: 1. Plates: being used to manufacture large-diameter straight seam submerged arc welded steel pipe into the production line, the first full-board ultrasonic testing; 2. Milling: Milling Machine through the two edges of the plate milling on both sides so as to achieve the requirements of the plate width, plate edge parallelism and groove shape; 3. preflex side: the use of pre-bending machine for plate edge pre-bending, the plate edges have to meet the requirements of curvature; 4. Forming : JCO forming machine in the pre-bent first half of the steel sheet after punching after several steps, pressed into a "J" shape, and then the other half of the same steel plate bent, pressed into a "C" shaped, finally forming an opening "O "shape 5. presoldering: so after forming the straight seam welded steel pipe commissure and the use of gas welding (MAG) for continuous welding; 6. internal welding: the use of tandem multi-wire submerged arc welding (up to four wire) in straight seam welded steel pipe inside; 7. outside welding: the use of multi-wire submerged arc welding in tandem LSAW steel pipe welding outside; 8. Ultrasonic examination Ⅰ: right straight seam welded steel pipe inside and outside the weld and weld on both sides 100% of the base material inspection; 9. X-ray examination Ⅰ: 100% of the external weld of the X-ray inspection television industry, the use of image processing system to ensure the detection sensitivity; 10. expanding: the SAW straight expanding the entire length of seam steel pipe to improve dimensional accuracy and to improve the distribution of internal stress tube; 11. pressure test: hydraulic test machine on the steel pipe after expanding to test each tube meet standard requirements in order to ensure test pressure, the machine has an automatic recording and storage capabilities; 12. chamfer: The inspection of steel pipes for pipe end after processing, to meet the requirements of the pipe end beveling size; 13 Ultrasonic Inspection Ⅱ: ultrasonic testing again, piece by piece to check in straight seam welded steel pipe flaring, hydraulic defects that may arise after; 14. X-ray examination Ⅱ: for expanded diameter steel pipe after hydrostatic testing and X-ray inspection and industrial television tube end welds film; 15. Magnetic particle inspection of tube ends: This check is performed to detect defects in the pipe ends; 16. corrosion and coating: after passing the pipe according to user requirements for corrosion and coatings. Use straight seam steel pipe mainly used in domestic water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. For the transport of liquids: water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipe for bridges; docks, roads, buildings and other structures tube. Welded steel pipe: also called pipe, which is cut by a narrow strip of steel strip, cold and wrapped into a tubular mold. Then special welding seam welding will then a tube. Outer weld polished bright. General inner pipe burr not fight. Only precision pipe before Hangzhou play within the burr. Corrosion of: welded steel strip or plate is bent with a circular, square and other shapes and then welded into the surface has a seam pipe. According to different methods can be divided into arc welding pipe, high-frequency or low frequency ERW pipe, gas pipe, stove pipe, Bundy tubes. Press the seam shape can be divided longitudinally and spirally welded pipe. Welded steel pipe used for oil drilling and machinery manufacturing. Stove pipe used for water and gas pipe, large diameter welded pipe for high pressure oil and gas transmission, etc.; spiral welded pipe for oil and gas transportation, piles, piers, etc. Lower cost than seamless steel pipe welded. |
