HP/LP Feedwater Heater Tube (U-Tube)
TIANBAO HP/LP feedwater heater tube is U shaped industrial tube, and thus is also called U tube. This industrial stainless steel tubing is ruggedly engineered for high pressure (HP) and low pressure (LP) feedwater heater in heavy-duty thermal power plant. Our industrial U stainless steel tube plays a predominant role in water circulation and reducing material cost.
Advantages
1. Our HP/LP feedwater heater tube is constructed with welded austenitic stainless steel pipe. We apply solution treatment or stabilizing treatment, as well as pickling and passivating treatment. Therefore, our seamless welded tubing is endowed with polishing inner and outer walls, and is free from defects such as crack, slag inclusion, layering, concave welding seam and incomplete penetration, etc.
2. In order to ensure unsurpassed quality of feedwater heater tube, we apply a series of inspection and testing covering melting analysis, tensile test, flattening test, hydrotest, eddy current test, radiographic inspection, as well as outer diameter, wall thickness, length and surface, etc.
3. Our stainless steel U tube is available in various steel grades to meet your requirements.
