  Liquefied 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. They require a national certification for the design and manufacture of Class 3 pressure vessels. Shandong Heze Boiler Factory Co., Ltd. is a national-approved enterprise for the design and manufacture of Class 1, 2, and 3 pressure vessels, capable of producing pressure vessels like liquefied gas storage tanks under 200 cubic meters. It is one of the few companies able to produce such products.200Cubic Corporation.

Advantages of our company's LPG storage tanks: 

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

  Two, all main pressure materials are customized steel plates from Jining Steel and Ansteel, with thickness deviations exceeding national standards.***Standard Specifications50m3For example, with a liquefied gas storage tank, the standard nominal thickness of the cap is used to ensure the design service life of the tank.14mmOur company uses custom steel plates for the caps.***Light thickness14.7mmSheet steel. (Other companies have limited production capacity and cannot customize sheet steel, so they either directly purchase14mmSteel plate, may result in premature scrapping during future inspections due to insufficient thickness of the head end curvature; either adopt16mmSheet metal fabrication, resulting in waste of resources and additional costs for the customer. 

  Three, prior to production, the customized steel plates purchased need to be delivered to the production workshop.100%Ultrasonic re-inspection to further ensure steel plate quality, guaranteeing the production of superior products. 

  Four: Products are produced on an assembly line with standardized operations. This has improved efficiency and ensures the smooth operation of the quality system, guaranteeing the quality of the products. 

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

  All pressure parts are焊接 with full penetration structure to ensure welding strength. 

  All liquefied petroleum gas tanks undergo full tank stress-relieving heat treatment. The company has constructed two gas-fired whole tank heat treatment furnaces, with a single furnace capable of handling300F椭形储罐DN≤4000mm，LTotal ≤25000mmThe lifespan and safety quality of the product are greatly influenced by this. It is also a major highlight of our company's external sales. 

Inspection (at various inspection points) 

  Eight, 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-type100%Surface flaw detection ensures welding quality. The company has a non-destructive testing room and employs certified inspectors at all levels. 

 Ten. Each unit undergoes hydrostatic testing to ensure equipment strength safety; each unit is tested for air tightness to guarantee equipment sealing performance. After hydrostatic testing, internal air is blown and cleaned. 

  Eleven, the company has2A cabinet shot blasting room, all tanks are treated with pneumatic steel shot blasting for rust removal, ensuring both the appearance quality and paint quality. (After overall shot blasting and rust removal, the lifespan of the paint 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 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. 

  Chapter 13: Witnessing the Project4000Over 10,000 customers worldwide, ensuring your peace of mind in purchase.

Safety Precautions for Natural Gas Storage Vessels: Jacketed vacuum insulated powder insulated pressure vessels used for storing and supplying low-temperature liquefied gases. Widely used in industrial production. Analysis of the hazardous characteristics of low-temperature liquids: Low-temperature liquids have low boiling points, high expansibility, strong asphyxiating properties, and strong oxidizing properties. Boiling points at 101.3 KPa: Liquid nitrogen -196°C, liquid oxygen -183°C, liquid argon -186°C. Contact with the human body can cause severe frostbite on the skin and eyes. In case of minor leaks or internal leakage in valves and pipes, they absorb heat from the surrounding environment, causing rapid condensation and frost formation at the leak point, which may freeze severely. If low-temperature liquids absorb high heat from the surrounding environment or a large amount of energy due to leakage, their volume will expand rapidly due to rapid vaporization. At 0°C and 101.3 KPa pressure, the volume of gas produced from 1L of low-temperature liquid vaporization: nitrogen 674L, oxygen 800L, argon 780L. In sealed containers or pipes, an increase in internal pressure due to vaporization of low-temperature liquids can easily cause overpressure explosions. In the environment near low-temperature liquid storage tanks, the vaporization of leaked low-temperature liquids can easily form a rich gas area. High concentrations of nitrogen, argon, or carbon dioxide can cause asphyxiation injuries. Additionally, high oxygen concentrations can also cause oxygen enrichment injuries. Oxygen is a strong oxidizing agent with extremely strong oxidizing properties. Liquid oxygen can adhere to clothing fabric and is easily ignited by a flame source, causing flash fires and personal injury.
