I remember a call from a fabrication manager in Texas who was convinced he had the answer. "We qualified one procedure five years ago," he said. "We've been using it on every heat exchanger since. Why would I need ano...
I remember standing in a boiler shop in Ohio a few years ago, watching three different welders work on the same tube bundle. Each one had their own technique. One ran a tight arc and moved fast. Another held a longer arc and to...
I remember walking through a boiler fabrication shop in Pennsylvania a few years ago. The production manager stopped me in front of a massive tubesheet—over two meters across, with hundreds of tube holes staring back at us. “Ev...
I remember watching a radiator shop in Ohio struggle with a batch of 500 industrial cooling cores. The tubes were thin-walled copper, the header plates were brass, and every single tube-to-header joint had to be leak-...
I remember walking into a heat exchanger shop in Louisiana about five years ago. The production manager pointed to a bundle of 1,200 tubes. “Every one of those joints has to hold 400 psi of sour gas—and I’ve got three...
I remember standing in a heat exchanger shop in Texas, watching a welder struggle with a tight tube bundle. He had maybe 10 mm of clearance between tubes, could barely see the joint, and was trying to walk the cup aro...
Boiler tube welding is a demanding process in boiler, heat exchanger, and power-generation equipment manufacturing. A typical boiler may contain hundreds or thousands of tube connections, and every tube to tubesheet joint must ...
If you've ever welded carbon steel pipe, you know the routine. Grind the bevel, set the gap, strike the arc, and pray the wind doesn't blow your shielding gas away. Carbon steel is forgiving—much more than stainless. It conduct...
Ask any welding engineer what keeps them up at night, and they won't say machine breakdowns or delivery schedules. They'll say parameters. An orbital TIG welder is only as good as the numbers you punch into it. Get the current...
From cross-country transmission pipelines to refinery process lines, every successful pipeline begins with a reliable pipe to pipe joint. In modern oil and gas pipeline construction, thousands of welded joints must meet strict ...
