The largest users of the valve are the petrochemical industry, the power sector, the metallurgy sector, the chemical industry and the urban construction sector. The petrochemical industry mainly adopts API standard gate valves, globe valves and check valves; the power sector mainly adopts high-temperature pressure gate valves, globe valves, check valves and safety valves for power stations, and low pressure butterfly valves and gate valves for part of the water supply and drainage valves; the chemical industry mainly adopts them. Stainless steel gate valve, globe valve and check valve; metallurgical industry mainly adopts low-pressure large-diameter butterfly valve, oxygen globe valve and oxygen ball valve; urban construction department mainly adopts low-pressure valve, such as large-diameter gate valve mainly used in urban tap water pipeline; The middle line butterfly valve, metal seal butterfly valve mainly used in urban heating, etc.; oil pipeline mainly uses flat gate valve and ball valve; the pharmaceutical industry mainly uses stainless steel ball valve; the food industry mainly uses stainless steel ball valve. Due to changes in user needs, the market trend of valve products will also undergo corresponding changes. The main development trends in the future will be as follows:
1. With the shift of petroleum development to oil fields in the interior and offshore oil fields, and the development of thermal power and hydropower and nuclear power from 300,000 kilowatts or less of thermal power in the power industry, valve products should also be changed in accordance with changes in equipment applications. Performance and parameters;
2. The urban construction system generally adopts a large number of low-pressure valves, and develops to environmentally-friendly and energy-saving types, that is, the low-pressure iron gate valve used in the past has gradually turned to environmentally-friendly rubber sheet valves, balance valves, metal-sealed butterfly valves, and midline-sealed butterfly valves. The development of oil and gas transmission projects in the direction of pipelines requires a large number of flat gate valves and ball valves.
3. The other side of energy development is energy conservation. Therefore, from the perspective of energy conservation, steam traps must be developed and developed to subcritical and supercritical high parameters.
4. The development of the power station is going to large-scale development. Therefore, it is necessary to use large-diameter and high-pressure safety valves and pressure reducing valves, as well as fast opening and closing of valves.
5, for the needs of complete sets of projects, valve supply from a single species to more varieties and more specifications. The need for a valve for an engineering project is increasingly provided by a valve manufacturer.
Thermal oil heaters
Our product range includes biomass fired thermal oil heaters, coal fired hot oil boilers, oil/gas fired thermal oil heaters and molten salt heaters. We also offer thermal oil heaters systems and solutions.
The manufacture of round coil tube adopts CNC coil tube automatic production line. Once-forming and no need for plastic .
The tube butt adopts argon arc welding technique and the seams will be done x ray real-time imaging, preventing unqualified seams from entering coil production line .
Heater is wholly assembled before delivery, it is easy for installation, debugging and operating.
Fully automatic operating, burning, liquid level of high level tank, outlet temperature and flow rate are adjusted automatically and self-protected.
The inlet and outlet with end flanges and flanged cover structure facilitate the installation and layout of tubeline in boiler house.
Internal side adopts good insulation material, outside uses stainless steel plate, which can mostly reduce heat lost and make working environment better.
Multilayers closely spaced tube bundle and steel rod is used to seal and fix, completely eradicating short circuit of flue gas.
The inner coil tube has bigger flow rate, so it is more stable under high temperature operation.
Conical coil effectively protects the furnace wall at the end of heater and burner on the top.
