Automated tube welding of heat exchangers

  • Converting from Manual to Automated WeldingTube-Fastening RequirementsStyle RequirementsProject ExpansionSix years ago, Harris converted to automated orbital welding from hand welding tubes to tube sheets. The need for increased production and customer demand for increasingly higher quality dictated this change. The company selected orbital welding equipment from Astro Arc Polysoude. Orbital welding allows the company to weld inside and outside a tube and run a fillet weld around an outside edge of a tube, which was needed to meet certain customer requirements.Heat Exchange Welding Stainless Pipe Tube ASTM A213 For Welding Stainless Steel Heat Exchange Tube ASTM A213 For Air Condenser Our heat exchanger tube with pickling and annealing surface is very popular in boilers and heat exchangers industry , water heater industry , air-conditioning industry etc . This kind of seamless tubes are have a very important position in our all products . China welding stainless steel boiler tube rolling piping Length:up to 18.3 meter. Bright annealed:1040 Welded seam treatment:inner welded seam removed. Product:welding stainless steel boiler tube rolling piping for heat exchanger Name:boiler tube rolling. Application machine:heat exchanger, boiler, condenser,evaporator. HG 20537.2.

    Girth flange/Flanges for heat exchangers shell-and-tube

    Girth flanges are used for mating two segments of a pressure vessel. These parts are also widely used in shell and tube heat exchangers and other process equipment to mate various components. There are two common kinds of girth flange such as welded hub joint, loose type (without hub). Heat Exchanger Repair - With Pipe Beveling MachinesNo matter whether it is on-site or in the plant the repair of the heat exchanger can easily be done with the right equipment. DWT provides a fast and effective solution to remove pipes with a higher wall-thickness from the tube sheet. Our pipe beveling machines MF2iw and MF3iw with a special milling head removes the old pipe and makes weld preparation for the new pipe in one operation. Heat Exchanger Welding Equipment-Heat Exchanger Heat Exchanger Welding Equipment ABK Machinery has put together automated welding machine systems for pipes, tanks, boilers, heat exchanger, LPG bullets and vessels welding fabrication. Welding automation positioning systems to meet the needs of a variety of application such as wind towers fabrication, vessel building, tank girth seam welders and pipe welding applications.
