\"U\" Stainless Steel Tubes are manufactured in our plant as per the customer requirements. Bend can be Heat Treated in accordance with Client\'s Requirements followed by hydrostatic testing and dye penetrant testing if required.
U-bend stainless steel tubes are widely used in heat-exchanger systems.Heat exchanger equipment on the basis of seamless stainless U-tubes is essential in strategically important and critical fields-nuclear and petro-chemical machine building.
Utube heat exchangers Designed for high temperature applications,especially for steam? condensing or hot oil systems.This model is selected when differential expansion makes a fixed tube sheet exchanger unsuitable and when conditions preclude a floating head type(HPF) selection.

Specialty and Advantages

Our company has been dedicated to producing stainless steel seamless pipe since 2003, owning complete producing technology and abundant managing experience. The raw material such as mother tube, round bar we use is from Chinese biggest and well-known steel mill: Bao Steel and Yongxing Steel. We have advanced NDT equipments for the tests such as Eddy Current test, Ultrasonic test, Hydraulic test and so on. We have ISO 9001 certificate, and the Third Party Inspection Certificates such as TUV, BV, Lloyd’s, SGS, etc, also can be provided according to customers’ requirements, Wooden case package which is strong and suitable for sea transportation is our main method to pack the pipes. And the economical packing method such as packed in bundles is also welcomed by some customers. The tolerance control we use is 0.1mm on both inside and outside Diameter and Wall Thickness, which is much higher than inte
