U tubes are manufactured in accordance with TEMA R specifications and can be supplied to most outside diameters, thicknesses, material specifications and radii.

Great for oil and gas plants, chemical and petrochemical plants, power generation plants and refineries, Heat Ex Tube Limited supply an extensive range of U tubes, guaranteed to match your industrial needs.

U tube testing

U tubes are rigorously tested to ensure they offer high quality and functionality.

If you require tubes to be heat treated, this is not a problem for us at  Heat Ex Tube Limited - we can target bend areas and straight leg sections to meet your specific requirements.

We test our U tubes to ensure they are up to industry standards. They are hydrostatically tested at the recommended pressure to check for leaks and we use the dye penetrant test to visually inspect cracks in the tube. The PMI test is used to inspect the physical properties of the tube.
