Product Description

U-tube heat exchanger U-shape heat exchangers are very popular and commonly found in industrial use. This is mainly due to their versatility. U-shape heat exchangers is composed of tube box, barrel, head, heat exchange tube, pipe, baffle plate, anti-impact plate and diversion tube, anti-short circuit structure, supporting and other accessories of the shell and tube.
U-shaped tube heat exchanger has only one tube plate, both ends of the tube are fixed on the same tube plate, the tube can be free expansion, no thermal stress, and can also solve the problem of thermal compensation effectively.The tube side adopts double tube side, the process is longer, the flow rate is higher, the heat transfer performance is better, the bearing capacity is strong, the tube bundle can be extracted from the shell, easy to repair and cleaning, and the structure is simple, the cost is cheap.It is suitable for large temperature difference between pipe and shell wall, or the shell side medium ,which is easy to scale and need cleaning, and it is not suitable for floating head type and fixed tube plate. It is especially suitable for high temperature, high pressure and corrosive materials which are not easy to scale and clean in tube

Applications:
Oil refining, petrochemical , natural gas chemical, coal chemical, shale oil , synthetic resin and plastic, rubber, chemical fiber, chemical, pharmaceutical, daily chemical, chemical additives , metallurgical , power , light, food and other industries of material preheating, heating, cooling, distillation, distillation, concentration, material and the heat back Collection, tail gas treatment and other processes industrial.

Advantage:
1) The tube bundle of u-shaped heat exchange tube can float freely without considering of the temperature difference stress, and can be used in large temperature difference occasions. 2) Only have one tube plate, less flanges, less leakage points, simple structure. 3) Reliable operation and low cost. Tube bundle can be drawn out and tubes between can easy to be cleaning.

The equipment material can choose all kinds of stainless steel and other metal materials, the heat exchange tube adopts special seamless steel tube for heat exchanger, and the heat exchange area can be customized as required. The tube sheet and baffle are punched by nc drilling to ensure the accuracy of the hole. Tube plate and heat exchange tube welding joint adopts automatic TIG welding, hydraulic expansion joint, the quality is safety, reliable and durable. Prettech U-shape heat exchangers adopts advanced bending technology, the thinning amount of heat exchange tube has been strictly controlled. At the same time,we paid much attention to the vibration of equipment in the design, which can guarantee the lifetime of the equipment.
