Internally rifled boiler tubes are also called Multi Lead Rifle boiler tubes. It is a special-shaped steel pipe with spiral ribs on the inner surface. Due to the concave-convex internal thread on the inner wall, it can effectively overcome the laminar flow caused by the slow flow of the medium in the steel pipe and suppress the steam film effect on the inner wall of the steel pipe. Therefore, the heat transfer effect of the boiler water wall is greatly improved, and the tube wall temperature is more uniform. Internally rifled boiler tubes are mostly used to make the water wall tube of the boiler wall. It is the main heat exchange component of the power station boiler. It rotates the water in the tube through the spiral rib on the inner wall of the tube, thereby destroying the film effect in the heat transfer process. , To achieve the effect of nucleate boiling. Internally threaded pipes are divided into ordinary internally threaded pipes and optimized internally threaded pipes. Ordinary internally threaded pipes are divided into type A and type B. The helix angle is 30°. Compared with ordinary round pipes, the heat transfer efficiency can be increased by 30%. The optimized internally threaded tube is a new generation of internally threaded tubes developed on the basis of the traditional internally threaded tube. Its thread lift angle reaches more than 40°. Compared with the ordinary internally threaded tube, it can increase the heat transfer efficiency by 20%. Compared with traditional internally threaded pipes, it has a better heat transfer effect.

ASME SA-556M Seamless Steel Tubes For High Pressure Feedwater Heater

In order to reduce the loss caused by the heat being taken away by the cooling water in the condenser, feed water heating is used to reduce this loss, that is, after the high pressure feed water pump, a high pressure heater is added to increase the boiler feed water temperature, improve economic benefits, and save Coal resources. Among them, the heat exchanger tube is its important core component, and its forms are U-shaped, flat-bottomed tube, straight tube and other forms. Straight pipes are mostly used to fix the tube sheet at both ends of the tube sheet heat exchanger tube bundle into a single body with the shell. The structure is simple, but it is only suitable for heat exchange operations when the temperature difference between the cold and hot fluids is small and the shell side does not require mechanical cleaning. When the temperature difference is slightly larger and the shell side pressure is not too high, an elastic compensation ring can be installed on the shell to reduce thermal stress.

Small diameter welded pipe, also called a small-caliber welded steel pipe, is a steel pipe made of steel or strip steel after crimping and welding. The small-diameter welded pipe has a simple production process, high production efficiency, many varieties and specifications, and less equipment, but the general strength is lower than seamless steel pipe. Since the 1930s, with the rapid development of high-quality strip, continuous rolling production, and the advancement of welding and inspection technology, the quality of welds has been continuously improved, and the variety and specifications of small-diameter welded pipes have been increasing, and they have replaced them in more and more fields. Seamless steel pipe. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of welds.

Studded tube is also called nail head tube. In the fields of petroleum refining and chemical industry, coal chemical industry, metallurgy, ceramics, building materials, etc., stud tubes are widely used. Especially in the convection chamber of the tube heating furnace, in order to enhance the heat exchange effect outside the tube, the heat transfer element often uses a nail-head tube. The area of the studded tube is 2 to 3 times that of the light tube, which can improve the heat transfer coefficient on the flue gas side.

Serrated finned tube. Mainly suitable for gas-based heating furnaces and various types of heat exchange equipment in petroleum, chemical, metallurgical, electric power, textile, and other industries. At present, the general spiral finned tube has the following deficiencies: 1. The light fins cannot make the airflow passing through the fins generate turbulence, and the heat transfer efficiency is low; 2. The light fins high-tooth winding fin roots have wrinkles and are easy to accumulate Dust and dust accumulation are not easy to remove; 3. It is not conducive to the selection of small diameter and high fin-shaped fin tubes; 4. The temperature stress in use is large.

There are many types of finned tubes. Although high-frequency welding finned tubes are more advanced in terms of product quality and production automation compared with inlay and brazing methods. Due to its factors such as difficulty in welding the root and wrinkles at the root cause many shortcomings in heat exchange efficiency and fouling prevention. By comparison, the Laser welding finned tube is the most advanced product of irreplaceable advantages. It has a high penetration rate, can prevent crevice corrosion, prolong service life and reduce heat transfer resistance. Breaking through material restrictions. And it can use different materials for processing, saving material costs, and easy for secondary processing.
