Our company specializes in tank-type pressure vessels, which are among our key products. These include LPG storage tanks, liquid ammonia tanks, liquid chlorine tanks, propane tanks, pentane tanks, and low-temperature storage tanks for liquid oxygen and nitrogen. Particularly, our LPG storage tanks have reached mass production with a continuous production line, and various models are available in stock. Volumes range from 5 to 200 cubic meters, and they are available in both above-ground and underground tank options.
Procedures for Safe Operation of Liquefied Petroleum Gas Above-Ground Storage Tanks
1. Use tanks in accordance with national specifications and design parameters; strictly prohibit overpressure and exceeding liquid level usage.
2. Inspections are strictly conducted according to regulations; tanks that fail to meet standards are not to be put into use.
3. Various safety accessories of the storage tank must be inspected regularly in accordance with regulations to ensure proper operation.
4. Valves connected to the storage tank should be clearly marked, with normally open and normally closed valves distinguished.
5. The storage tank's liquid volume should be strictly controlled at 85% or below, with clear level gauge limit markings.
5. Promptly empty the tank if overfilling is detected.
6. Conduct daily routine checks of the tank's pressure, temperature, and level, and promptly address any anomalies and report them.
7. When the summer temperature reaches above 35℃ and the storage tank pressure exceeds 10 kgf, the sprinkler cooling system must be activated.
8. When the winter temperature falls below 5°C, daily draining and inspection of the storage tank should be conducted to prevent ice blockage.
Materials used for liquefied gas storage tanks:Q345RThis is a special steel plate for pressure vessels; this equipment has undergone high-temperature heat treatment after quenching and tempering.,Huzhou Boiler Factory Co., Ltd. is one of the top competitive private enterprises in the domestic pressure vessel manufacturing industry, particularly renowned for its independent low-temperature storage tanks.|Low-temperature thermal insulation storage tank(LiquidCO2,Liquid Nitrogen,Liquid Oxygen, Liquid Argon)Frame-type low-temperature thermal insulation storage tank|Tanks, frame-type container,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 consultation, design, production, integration, and installation and debugging services.
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 the design and manufacturing of Class 1, 2, and 3 pressure vessels. We can produce pressure vessels such as liquefied gas storage tanks below 200 cubic meters. We are one of the few companies capable of producing such products.200Cubic Enterprise.
Our Liquefied Gas Storage Tanks Advantages:
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 Jigang and Angang Steel, with all thickness deviations exceeding national standards.***Standard Specifications50m3For example, with a liquefied gas storage tank, to ensure the design service life of the tank, the nominal thickness of the standard end cap is14mmOur company uses customized steel plates for the caps.***Thin gauge14.7mmSteel plates. (Other companies have low 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; or opt for16mmSheet metal fabrication, leading to resource wastage and imposing additional costs on the client.
Section 3: Prior to production, the customized steel plates purchased must be delivered to the production workshop.100%Ultrasonic re-inspection ensures steel plate quality once more, guaranteeing the production of superior products.
Four: The product is 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 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 full stress-relieving heat treatment. The company has built two gas-fired integral heat treatment furnaces, with a single unit processing capacity300FIFO 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 external sales.
Inspection (at various inspection points)
Eight, throughout the product manufacturing process, from raw materials to factory to product inspection and shipment, set up various inspection checkpoints to effectively control product quality.
Section 9: All Main Weld Joints100% XRadiographic inspection, fittings, flangesC、DWelding-like100%Surface flaw detection ensures welding quality. The company has a non-destructive testing room and employs certified inspectors at all levels.
Ten. Individual hydrostatic testing ensures equipment strength safety; individual air tightness testing ensures equipment sealing performance. After hydrostatic testing, internal air blow cleaning.
Eleven, the company has2A cabinet shot blasting room, all tanks are treated with pneumatic steel shot blasting for rust removal, 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. Standard products are available in stock, allowing clients to shorten construction cycles and earn profits sooner.
Section 13: Witness the Project4000Customers in over 100 countries worldwide, ensuring your peace of mind in purchase.
