  200 thousand tons of methanol (convection section module of reformer tube) by Qingdao Hexin Machinery Co., Ltd. The ethylene cracking furnace is divided into a convection section and a radiation section. Generally speaking, the function of the convection section is to recover the waste heat of the flue gas, which is used to preheat and vaporize the raw oil, and superheat the raw oil and dilution steam to the cross temperature of the material, and the remaining Heat is used to superheat ultra-high pressure steam and preheat boiler feed water. In the process of preheating and vaporizing raw materials, dilution steam is injected to reduce the vaporization temperature of raw oil and prevent raw oil from coking during the vaporization process. Each group of disks in the convection section of the cracking furnace The tube is mainly composed of heat exchange furnace tubes (smooth tubes or finned tubes) welded by return elbows. The end tube sheets and the middle tube sheets support the furn

  Stud Tubes for Convection Chambers by Qingdao Hexin Machinery Co., Ltd. The nail head tube (also known as the needle tube) adopts a square or hexagonal arrangement and is equally divided into cylindrical needles welded on the surface of the heat exchange tube. The square or hexagonal reinforced heat exchange nail head tube is assembled and welded to form a high-efficiency and energy-saving needle tube heat exchange tube group. Because the nail head tube needle rib is a cantilever structure and has a compact structure, under the impact of the air flow, the needle rib will produce Vibration makes it difficult for soot to accumulate; coupled with the strong turbulent scouring of the flue gas, the heat transfer efficiency of the heat exchange element of the nail head tube is high, and it has a strong self-cleaning ability. The nail head tube group is especially suitable for compact waste heat boilers, oil-fired, gas-fired boilers and oil heaters. Under the same heat exchange, its weight

Finned Tubes for Convection Chambers by Qingdao Hexin Machinery Co.,Ltd.

Image
 Finned Tubes for Convection Chambers  by Qingdao Hexin Machinery Co.,Ltd. A finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added on the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency, such a heat exchange tube. As a heat exchange element, finned tubes work in high temperature flue gas conditions for a long time. For example, finned tubes for boiler heat exchangers are used in harsh environments, high temperature and high pressure and in a corrosive atmosphere. This requires finned tubes to have high performance. index. 1), anti-corrosion performance (Anti-corrosion) 2), wear resistance (Anti-wear) 3), low contact resistance (lower contact resistance) 4), Higher Stability 5), anti-fouling ability HEXIN Machinery produces various OEM wear and corrosion resistant components for the cemen
