The material used for the liquefied gas storage tank is Q345R, a special steel plate for pressure vessels. This equipment has been heat-treated with high-temperature annealing. Heze Boiler Factory Co., Ltd. is one of the outstanding private enterprises with strong competitiveness in the domestic pressure vessel manufacturing industry, particularly in independent low-temperature storage tanks, low-temperature insulated storage tanks (liquid CO2, liquid nitrogen, liquid oxygen, liquid argon), frame-type low-temperature insulated storage tanks/tanks, frame-type tank containers, as well as other chemical pressure vessels.Liquid Ammonia Storage Tank, Liquid Chlorine, Ethylene Oxide Storage Tank,Ethylene, Propane Storage Tank,Propylene)Aspects, After years of accumulation, we have developed a series of products, user solutions, and equipment installation and debugging technologies, offering comprehensive solutions including consultation, design, production, integration, and installation debugging services.

  Liquefied petroleum gas storage tanks are pressure vessels used for storing liquefied petroleum gas. They are special equipment that can only be produced by enterprises approved by the National Quality Supervision and Inspection总局. These tanks require a Class 3 pressure vessel design and manufacturing qualification issued by the state. Shandong Heze Boiler Factory Co., Ltd. is a state-approved design and manufacturing enterprise for Class 1, 2, and 3 pressure vessels, capable of producing pressure vessels like storage tanks below 200 cubic meters. It is one of the few companies that can produce such equipment.200Cube Enterprise.

Advantages of our liquefied gas storage tanks: 

  One, our company conducts an annual quality assessment for all suppliers to ensure supplier quality. 

  Two, the main pressure materials are all customized steel plates from Jining Steel and Ansteel, with all thickness deviations exceeding the national standards.***Standard Specifications50m3For example, with a liquefied gas storage tank, the nominal thickness of the standard cap is used to ensure the design and service life of the tank.14mm, but our company uses customized steel plates for our caps***thin thickness14.7mmSheet steel. (Other companies have limited production capacity and cannot customize sheet steel, so they either directly purchase14mmSteel plates may potentially lead to premature scrapping in future inspections due to insufficient thickness of the head curvature; or opt for16mmSteel plate production leads to waste of resources, imposing additional costs on the client. 

  Section 3: Prior to production, the customized steel plate purchased must be transported to the production workshop.100%Ultrasonic re-inspection to further ensure steel plate quality, guaranteeing the production of superior products. 

  Four: Products are manufactured on an assembly line with standardized operations. This has increased efficiency and ensured the smooth operation of the quality system, guaranteeing product quality. 

  Five, the main body of the product is焊接 using both internal and external automatic welding, ensuring welding shape and internal quality. 

  All pressure-bearing components are welded with full penetration structure to ensure welding strength. 

  Section 7: All LPG storage tanks undergo integral stress-relieving heat treatment. The company has built two gas-fired integral heat treatment furnaces, with a single unit having a processing capacity of300Portable Storage TankDN≤4000mm，LTotal ≤25000mmThe lifespan and safety quality of the product are greatly influenced by this. It is also a major selling point for our company's exports. 

Inspection (at various inspection points) 

  Section 8: During the product manufacturing process, from raw materials to factory and product inspection before shipment, set up various inspection checkpoints to effectively control product quality. 

 All main weld seams100% XRadiation Detection, Fittings, FlangesC、DWelding-like100%Surface flaw detection ensures welding quality. The company has a non-destructive testing room and employs certified inspectors at various levels. 

 Ten, individual hydrostatic testing to ensure equipment strength safety; individual air tightness testing to ensure equipment sealing performance. After hydrostatic testing, internal air blowout cleaning. 

  Eleven, the company has2A fully enclosed shot blasting room, all tanks are treated with an air-powered steel shot blasting process for rust removal, ensuring both exterior quality and paint quality. (After overall shot blasting and rust removal, the paint's lifespan can be significantly extended.) Apply two coats of anti-rust primer followed by two coats of topcoat; four layers of paint guarantee the tank will not peel for up to five to ten years, and with good maintenance, it can last up to twenty years without repainting. 

  Twelve, large production capacity, customers can see the real products at the company. Regular products are available for immediate supply, allowing customers to shorten the construction cycle and make money sooner.

Attachment: Safety valves and pressure gauges are mandatory for strict inspection. It is essential to report for inspection at the local quality supervision bureau. This ensures better usage for the users. If the pressure gauge fails, you won't know the exact pressure used by your terminal, and you can't use it with peace of mind, fearing issues with the liquefied gas storage tank. Both the air compressor and the storage tank itself have safety valves. When pressure exceeds the safe setting of the safety valve, it will automatically release pressure, and the pressure gauge plays a significant role. Therefore, daily accessories of special equipment must be used with caution. If there are any issues, first confirm if the steel plate thickness of the storage tank meets the standards, and if not, determine the cause of the steel plate corrosion. Also, reconfirm if the safety valves, pressure gauges, and other auxiliary equipment meet the requirements. If all are found to be不合格, the local technical supervision bureau of the enterprise will issue an inspection不合格 notice, and the enterprise will replace the new pressure vessel upon receiving the notice.
