Stuffing-box sealing structure is adopted, the tube bundle can extend or contract freely in the shell shaft; no thermal stress will be generated for thermal deformation difference between shell walls.
Compared with a floating-head heat exchanger, it has a simpler structure, easier fabrication and manufacturing, lower consumption of materials and lower manufacturing cost; besides, the tube bundle can be extracted from the shell; the inside of the tubes and the faces between tubes can be easily cleaned and maintained.
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.
The stuffing box heat exchanger 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 argon arc welding, hydraulic expansion joint, quality safety and reliable, durable.
Advantage:
1.The structure is simpler than the floating head heat exchanger, easy to manufacture, metal consumption is about 10% lower than the floating head, low cost
2.he tube bundle can be taken out from the shell,it's easy for clean and maintenance.
3.Stainless steel material ,long service life.
4.Fexible design,complete specification,Practical and targeted,save money. Small footprint ,light weight ,easy assemble and saving civil investment.
