The material used for liquefied gas storage tanks 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 in the domestic pressure vessel manufacturing industry, particularly competitive in the production of 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 (LPG) storage tanks are pressure vessels used for storing LPG. 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 three-class pressure vessel design and manufacturing qualification. Shandong Heze Boiler Factory Co., Ltd. is a national-approved design and manufacturing enterprise for Class 1, 2, and 3 pressure vessels. It is capable of producing pressure vessels such as LPG storage tanks under 200 cubic meters. It is one of the few companies that can produce such products.200Cubic Enterprise.

Our liquefied gas storage tank advantages: 

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

  Two, all major pressure materials are custom steel plates from Jining Steel and Ansteel, with thickness deviations exceeding national standards.***Standard Specifications50m3For example, in the case of liquefied gas storage tanks, to ensure the design service life of the tank, the nominal thickness of the standard hemispherical head is14mm, but our company uses customized steel plates for our flanged heads***Thin thickness14.7mmSteel plates. (Other companies have limited production capacity and cannot customize steel plates, either directly purchase14mmSteel plate, may result in premature scrapping during future inspections due to insufficient thickness of the end cap curvature; either adopt16mmSteel plate manufacturing leads to resource wastage, imposing additional costs on the customer. 

  Section 3: Prior to production, the custom steel plates purchased need to be...100%Ultrasonic re-inspection to further ensure the quality of steel plates, guaranteeing the production of superior products. 

  Four: The products are produced on an assembly line, ensuring standardized operations. This has improved efficiency and guaranteed the smooth operation of the quality system, ensuring product quality. 

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

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

  Section 7: All LPG storage tanks undergo whole tank stress-relieving heat treatment. The company has built two gas-fired whole tank heat treatment furnaces, with a single unit processing capacity300Square Storage TankDN≤4000mm，LTotal ≤25000mmThe product's lifespan and safety quality play a significant role. It is also a major highlight of our company's foreign sales. 

Inspection (at various inspection points) 

  Section 8: During the product manufacturing process, from raw materials to factory to product inspection and release, set 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 is staffed by 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 to clean and clear. 

  Eleven, the company has2A portable sandblasting room, all tanks are processed with an air-powered steel shot blasting method for rust removal, ensuring both the surface quality and paint quality. (After the overall sandblasting and rust removal, the lifespan of the paint can be significantly extended.) Two coats of rust-inhibiting primer and two coats of topcoat are applied, with four coats guaranteeing the tank won't peel for up to five to ten years. With good maintenance, it can last up to twenty years without needing repainting. 

  Twelve, Large production volume, customers can see the real products at the company. Regular products are available for immediate delivery, helping customers shorten the construction cycle and make money sooner. 

  Thirteen: Witness Project4000Customers遍布全球， spanning all corners of the world, ensuring your peace of mind in purchasing.

Liquefied gas storage tanks are pressure vessels, and the national requirement is an annual inspection (with a recommended service life of 10 years for simple pressure vessels). Since inspections are conducted, there are products that pass or fail. Generally, due to improper usage procedures or lack of timely maintenance, businesses may find their liquefied gas storage tanks fail inspection, necessitating mandatory scrapping. As these tanks are special equipment, scrapping requires a specific process. Air compressor liquefied gas storage tanks are often considered safe special equipment, but if any aspect of manufacturing, design, installation, or usage management is not standardized, accumulated hazards could lead to explosion accidents or even more severe consequences. Therefore, we must adhere to the operating procedures for our air compressor liquefied gas storage tanks, avoid shortcuts, and never purchase inexpensive tanks from unqualified manufacturers. Tanks with a volume of 1 cubic meter and a capacity of 10 kg or less are classified as simple pressure vessels and do not require inspection. According to national regulations, they are exempt from inspection for 7 years from the date of manufacture on the label, but this applies only to the tank itself.
