Tube to Tubesheet Welding Machine. The OTS series orbital tube to tubesheet weld head is design for fabrication of various heat exchangers and boiler industry. It can be used for recessed, projected and flush tubing with or without wire feed. Tungsten Inert Gas (TIG) / Gas Tungsten Arc Welding (GTAW) head that efficiently welds tube to
Welding is a key skill when it comes to professional boiler repair, and you should look for a boiler repair company that can offer certified welding as a part of their services. Boiler tubes, which can corrode, form holes, or otherwise suffer damage after years of withstanding extreme pressure and high heat, are typically in need of welding
By expanding the tube inside the tubesheet, swaging ensures that the space between the two components is always forced closed. Hydraulic expansion is the direct application of high internal pressure within a tube or sleeve in order to form a tight joint between the tube and tube sheet or a tight seal between the sleeve and tube.
Tube-to-Tubesheet Welding. Tube to Tubesheet weld heads for autogenous or with filler wire welding. Weld heads can be configured with a wide selection of torches and configurations to match all common tube sheet design. AVC function is standard on the more complex heads. AMI’s proven tube sheet weld heads provide productivity and ease of
Seal welding, tube-to-tubesheet welds, heat exchanger, mock-up, tube expansion INTRODUCTION Heat exchangers are widely used in many ways and are seen in many types of industrial, commercial and residential applications. Heat exchangers come in many configurations, sizes and materials of
Jun 17, 2015· Strength-Weld Tubes To Tubesheet - posted in Process Heat Transfer: Hi, I have been going through one of the Shell and Tube Exchange Data sheet and at the end one note was mentioned saying Strength-weld tubes to tubesheet. As i understand this note is to prevent the Leakage from Shell side to Tube or Tube to Shell Side. But how we decide that we need to specify Strength-weld tubes to tubesheet
Dear Experts, I need to do tube to tubesheet welding for CS Steel that is tubesheet material is SA 516 Gr.70 thk 20mm and tube material is SA 179 thk is 2.108mm welding process is GTAW, i have WPS in GTAW process with 3G welding my doubt is this WPS is suit for above mentioned statement or i need to qualify any welder qualification for welding this process. kindly please suggest me what ill do.

Typical Tube Sheet. Where the tube and tube sheet materials are joinable, weldable metals, the tube joint can be further strengthened by applying a seal weld or strength weld to the joint. A strength weld has a tube slightly reccessed inside the tube hole or slightly extended beyond the tube sheet. The weld adds metal to the resulting lip.
Tube-to-sheet welding. Heat exchangers built up from tube sheets and tubes require substantial welding. On larger work pieces, several thousands of tubes have to be welded into the tube sheet. Therefore KRANENDONK has developed a mobile robot cell for tube-to-sheet welding. Tube expanding
