The materials used for the liquefied gas storage tanks are Q345R, a special steel plate for pressure vessels. This equipment has been heat-treated after high-temperature tempering. Heze Boiler Factory Co., Ltd. is one of the outstanding private enterprises in the domestic pressure vessel manufacturing industry, particularly competitive 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, and 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 consulting, design, production, integration, and installation debugging services.

  Liquefied gas 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. These tanks require national certification for design and manufacturing of Class 3 pressure vessels. Shandong Heze Boiler Factory Co., Ltd. is an authorized manufacturer for design and production of Class 1, 2, and 3 pressure vessels. We are capable of producing pressure vessels such as liquefied gas tanks below 200 cubic meters. We are among a select few companies able to produce...200Cubic Enterprises.

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, to ensure the service life of the tank, the nominal thickness of the standard封头is used.14mmOur company uses customized steel plates for our封头.***Thin thickness14.7mmThe steel plate. (Other companies have low production capacity and cannot customize steel plates; they can either purchase directly14mmSteel plate, may cause premature scrapping during future inspections due to insufficient thickness of the head curvature; either adopt16mmSteel plate manufacturing, resulting in resource waste and imposing additional costs on the customer. 

  Section 3: Prior to production, the customized steel plates purchased must 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 increased efficiency and ensures the smooth operation of the quality system, guaranteeing product quality. 

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

  All pressure-bearing components are焊接with full penetration structures to ensure welding strength. 

  Section 7: All LPG storage tanks undergo full stress-relieving heat treatment. The company has built two gas-fired integral heat treatment furnaces, with a single unit processing capacity300Firm Storage TankDN≤4000mm，LTotal ≤25000mmThe product's lifespan and safety quality are greatly influenced by this. It is also a major highlight of our company's sales to the international market. 

Inspection (at each inspection point) 

  Section 8: Throughout the product manufacturing process, from raw materials to the factory and to product inspection for shipment, establish 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 testers at various levels. 

 Ten, individual hydrostatic testing to ensure equipment strength safety; individual airtightness testing to ensure equipment sealing performance. After hydrostatic testing, internal air cleaning and sweeping. 

  Eleven, the company has2A cabinet shot blasting room, all tanks are treated with an air-powered steel shot blasting process 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.) Two coats of anti-rust primer are applied, followed by two coats of topcoat, with four layers of paint guaranteeing 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, users can see the real products at the company. Regular products are available for immediate delivery, allowing customers to shorten construction cycles and make money sooner. 

  Chapter 13: Witnessing the Project4000Customers above, spread all over the world, giving you peace of mind in your purchase.

Liquefied Petroleum Gas TankWe offer compressed gas or liquefied gas storage tanks.Liquefied Petroleum Gas TankFixed-volume storage tanks and variable-volume storage tanks, categorized by the change in container capacity, with large fixed-volumeLiquefied Petroleum Gas TankManufactured in spherical or cylindrical shapes. The mobile volume storage tank, also known as a low-pressure gas storage tank or commonly referred to as a gas holder, can alter its geometric volume. It is airtight, preventing leaks, and serves to balance air pressure and regulate gas supply, with pressure typically not exceeding 60MPa.

Liquefied gas storage tanks undergo rigorous quality assessments for the material of pressure components, dimensions, weld quality, operational quality, installation quality, internal fittings, and safety accessories.

Routine physical and chemical tests of the drum material, such as mechanical properties and chemical composition.

The weld joints, seams, tank end caps, and the mutual geometric positions of all pressure elements are rigorously inspected through X-ray non-destructive testing and magnetic particle inspection. Testing is conducted for the product's sealing, pressure resistance, and all technical indicators that could affect the safe operation of the product.
