Advantages of the Vacuum Autoclave Process

 Vacuum autoclave is one of the most common composite autoclave. According to the different production process, the type of composite autoclave selected is also different.




Advantages of the Vacuum Autoclave Process
1. Constant temperature, adjustable: The inside of large vacuum autoclave is heated by circulating hot air to heat the workpiece. And the temperature difference is small everywhere. At the same time, equipped with cooling system. As a result, the temperature can be strictly controlled within the process setting range.
2.Constant pressure: Using gas to pressurize, pressure through the vacuum bag to the workpiece surface. Furthermore the normal pressure at each point is equal, so that the workpiece is cured and formed under the same pressure.
3.Wide range of application: The mold is simple, high efficiency. Not only suitable for large area of complex surface of the plate, shell, but also suitable for simple shape of the plate, rod, tube, block. It can also be used for bonding assembly, small parts can be cured at the same time.
4.Stable and reliable molding process: Pressure and temperature are average, adjustable and controllable. So that the quality of molding or handover system is different and reliable; low porosity, controllable and average resin content; vacuum can be pumped when pressurizing, so that low molecular substances can be easily discharged.
5.Vacuum autoclave curing process: Regarding the process settings of some important products. It is possible to set special equipment control parameters and complete historical calling, to complete the puppet position setting, to complete the interspersed and docking of vacuum sampling pipes, and to complete equipment I /O inspection, etc.
The completion of the above process also requires a powerful software operating system.

Surge Vessel for DWTP of France Project Company Successfully Delivered

 In March, the spring returns to the earth, all things recover. The grass grows and the warbler flies. On March 25, 2022, the first batch of 5 sets of 50m3 and 1 set of 12m3 surge vessel for Cambodia Project Department of French Group . The surge vessel was manufactured by Taian Strength Equipment Co., Ltd. Finally, surge vessel was successfully delivered.





The surge vessel are also known as buffer tank, surge tank, air storage tank, pressure tank, etc. It is mainly used for the pressure fluctuation of the surge system in various systems. Such as central air conditioning, boiler, water heater, frequency conversion. And constant pressure water supply equipment. The pressure fluctuation of the surge system eliminates the water hammer. And it plays the role of pressure stabilizing unloading. So that the system works more smoothly.

Furthermore, the surge performance of the surge vessel is mainly achieved by the compressed air in the compression tank. When the water pressure or air pressure changes slightly in the system. The surge vessel will have a certain surge effect on the change of pressure. At last, it can ensure the stability of the pressure of the system. And the pump will not open frequently due to the change of pressure. Surge vessel was widely used in water supply equipment and central air conditioning system and other things.
France Group is a construction service company with a history of more than 100 years. And it is the world’s largest contracting, construction and related service company. Thanks to the original successful cooperation between our company and Vinci Myanmar surge vessel. On January 15, 2022, the Cambodia branch of France group came to us.
Baes on the the needs of the project, one water conservancy project department in Cambodia hopes that our company build 5 sets of 50m3 and 1 set of 12m3 surge vessel for them. The surge vessel design pressure is 1.6Mpa, ASME manufacture standard. Then whole surge vessel needs to be sandblasted (the sandblasting level needs to reach sa2.5), high-quality anti-corrosion paint. And the thickness of the paint film needs to be at least 450um. After obtaining the relevant technical requirements. Our engineers immediately invested in the relevant technical design work and formulated a detailed plan.
Thanks to the high-quality products provided by our company in previous projects. Afterwards, France company still has high trust in our company in this project. After the technical standards are confirmed, PO orders be confirmed by fax. Considering that the production of this project coincides with the Chinese Lunar New Year. In order to ensure that it can be completed within 60 days as scheduled. Our company immediately recruited elite soldiers to work overtime to complete the production.
On March 18, 2022, after the intensive and orderly production. The surge vessel successfully entered the hydraulic test work. The whole hydraulic test process have been witnessed by the inspectors of the France project department. The hydraulic test was successfully completed. And the surge vessel fully met the test requirements. After the hydraulic test was completed, our company immediately arranged rust removal and sandblasting for the whole surge vessel carried out strictly accordance with the requirements standards. After sandblasting and rust removal according to relevant requirements. The painting work should be arranged immediately.
Since this surge vessel project is used for drinking water, the quality requirements of the relevant paint thickness are also very high. Based on this high-quality requirement, our paint company chose Jotun, a world-renowned paint brand with high quality. In order to fully guarantee the final quality. Our company is not stingy in terms of paint thickness. The Vinci project department requires 450um, but after the final inspection by the third-party personnel of Vinci the paint thickness exceeds the quality requirements in an all-round way. Finally the customer is quite satisfied.
Considering the damage to cans of paint caused by inland and sea transportation. Our company has specially made a detailed packaging plan. After all procedures were completed and all project documents were submitted. Vinci staff were quite satisfied with our work and issued instructions to allow shipment.
Taking this opportunity of cooperation with surge vessel. Our company hopes to continue to provide customers with high-quality products in the future. Taian Strength Equipment Co., Ltd. sincerely welcomes friends from all over the world to come to our company to guide our work.

Ammonia Storage Tank

Ammonia storage tank (also called ammonia tank) is a special fixed pressure vessel for liquid ammonia. The saturated vapor pressure of storage medium is less than or equal to 2.03MPa at 50℃. And the design pressure is generally 2.16MPa. It is mainly used for indoor static storage of liquid ammonia. STRENGTH can produce ASME, CE(PED), GB150 (Chinese standard) liquid ammonia storage tanks. The tanks are generally used in desulfurization and denitrification projects of larger coal-fired boilers and biomass boilers, or in chemical enterprises that use ammonia as raw materials, etc.





During the use of liquid ammonia storage tank, reliable measures should be taken in all links of the whole quality assurance system from design, manufacture to use, as follows:
① Material selection. Practice has proved that the higher the material strength, the greater the possibility of stress corrosion. In order to prevent stress corrosion, the steel with lower strength should be selected as far as possible under the condition of comprehensive consideration of operating pressure, residual stress, safety and economy.
②The liquid ammonia storage tank adopts reasonable structure and welding process. Structurally, stress concentration caused by excessive welds, excessive concentration, asymmetric welds, intersection of welds and unreasonable welding sequence should be avoided. Manufacturing should avoid strong welding, to prevent biting side, wrong side and other defects, to ensure that the surface contact with the medium as smooth as possible. After fabrication, annealing treatment should be carried out to remove residual thermal stress after welding. Proper post-weld heat treatment can greatly reduce the residual stress in the manufacturing process and reduce the peak hardness of the weld heat affected zone.
③The air in the new liquid ammonia storage tank should be completely cleared before it is put into use. For example, in the process of filling, discharging and maintenance, take certain measures to avoid bringing in any air. As for large tanks, ammonia vapor should be continuously condensed. while the non-condensing gas is mostly air, which should be discharged. For smaller ammonia tank, air is removed from tanks by extraction or transpiration. In short, stress corrosion can be effectively prevented by eliminating air pollution in storage tanks.
④For the newly put into use liquid ammonia storage tank, internal and external inspection and periodic periodic inspection shall be carried out according to the provisions. Then the liquid and gas phase interface, arc starting and closing, type joint and other corrosive parts should be inspected. All welds below the liquid level should be tested by MT or UT. If conditions permit, all welds should be tested by MT.
⑤Regularly check the ammonia concentration and water content of liquid. If the water content is lower than the critical concentration, water should be added in time to keep the water content within the range.
Liquid ammonia storage tank often adopts dual system control, local instrument display and remote signal acquisition combined, including the application of MIOT system, leakage alarm, low liquid level alarm, misoperation alarm, emergency cut-off system and so on, a complete set of intelligent control system has the characteristics of simple operation, low failure rate, high safety.
