U Bending

We are manufacturer of U bending in kinds of materials such as carbon steel, stainless steel, alloy steel.

U bend tubes are used in heat exchangers, condensers, pre-heaters and other applications. Which according to: EN10216,DIN17175,DIN17173, A179,A213 TP316

U bend tubes for heat exchangers applied mostly in oil and gas plants, chemical and petrochemical plants, refineries, power plants and renewable energy plants. Low fin tubes can be supplied in the form of U bends.

Dimension Control

Ovality of straight and bending tube parts/Thinning of straight and bending tube parts
Leg spacing length/U bend tube length (leg + radius + (0,5 x OD))
Difference between legs length/Straightness of legs
Deviation from bend plane/Twist of bending portion
Squareness and cleanliness of tube ends
Complete visual control

Heat Treatment

Post bending heat treatment by electrical resistance is applied. The temperature is monitored and controlled during the process.

Test

Hydrostatic Test/Air Underwater Test/Pulsating Pressure Test/Dye Penetrant Test/Magnetoscopic test
