  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 Administration. They require a Class 3 pressure vessel design and manufacturing qualification issued by the state. Shandong Heze Boiler Factory Co., Ltd. is a national-approved enterprise for designing and manufacturing Class 1, 2, and 3 pressure vessels. It is capable of producing pressure vessels such as liquefied gas storage tanks under 200 cubic meters. It is one of the few companies that can produce such products.200Cubic Enterprise.

Our company's advantages in liquefied gas storage tanks: 

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

  Two, all major pressure materials are made from customized steel plates from Jining Steel and Ansteel, with thickness deviations exceeding national standards.***Standard Specifications50m3For example, with a liquefied gas storage tank, the nominal thickness of the standard head is used to ensure the design and service life of the tank.14mmBut our company uses customized steel plates for our caps.***Thin thickness14.7mmSteel plates. (Other companies have low production capacity and cannot customize steel plates; they can only purchase them directly.)14mmSteel plate; may result in premature scrapping during future inspections due to insufficient thickness of the head end curvature; or opt for16mmSteel plate manufacturing, resulting in resource wastage and imposing additional costs on the customer. 

  Section 3: Before the production of customized steel plates in the production workshop, the plates must...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, ensured the smooth operation of the quality system, and guaranteed the quality of the products. 

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

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

  Section 7: All LPG storage tanks undergo full stress-relieving heat treatment. The company has constructed two gas-fired integral heat treatment furnaces, with a single furnace having a treatment capacity of300FIFO Storage TankDN≤4000mm，LTotal ≤25000mmThe lifespan and safety quality of the product are greatly influenced by it. It is also a major highlight of our company's foreign sales. 

Inspection (at various inspection points) 

  Eight, during the product manufacturing process, from raw materials to factory to product inspection and release, set up various inspection stop points to effectively control product quality. 

 All main weld seams100% XRadiographic inspection, fittings, flangesC、DWelding Type100%Surface flaw detection ensures welding quality. The company has a non-destructive testing room and employs certified inspectors at various 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 to clean and clear. 

  Eleven, the company has2A cabinet type shot blasting room, all tanks are processed with an air-powered steel shot blasting rust removal technique, ensuring both exterior 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 volume, customers can see the real products at the company. Regular products are available for immediate supply, allowing customers to shorten their construction cycle and make money sooner. 

  Thirteen: Witnessing Project4000Over 1 million customers, worldwide presence, ensuring your peace of mind in purchasing.

Our company specializes in storage tanks, which are one of our key products. These include LPG storage tanks, liquid ammonia tanks, liquid chlorine tanks, propane tanks, C5 storage tanks, and low-temperature storage tanks for liquid oxygen and nitrogen. Particularly, our LPG storage tanks have reached mass production levels with a continuous production line, and various models are available in stock. Available capacities range from 5 to 200 cubic meters, and we offer both above-ground and underground tanks.

Procedures for Safe Operation of Liquefied Petroleum Gas Aboveground Storage Tanks

1. Utilize tanks in accordance with national regulations and design parameters; strictly prohibited from exceeding pressure and liquid level.

2. Inspections are conducted strictly according to regulations; tanks that do not pass are not to be put into use.

3. Various safety accessories of the storage tank must be inspected regularly according to regulations to ensure normal operation.

4. Valves connected to the tank, including normally open and normally closed valves, must be clearly marked.

5. The storage tank's liquid volume should be strictly controlled below 85%, with clear limit markings on the liquid level gauge.

5. Promptly drain the tank if it's found to be overfilled.

6. Conduct daily routine checks of the tank's pressure, temperature, and level; promptly address any anomalies and report them.

7. When the summer temperature reaches above 35℃ and the storage tank pressure exceeds 10 kgf, the spray cooling system must be activated.

8. When the winter temperature drops below 5°C, daily draining and inspection of the storage tank should be conducted to prevent ice blockage.
