It is suitable for applications such as wastewater treatment, purified water production, and seawater desalination.
• Metallurgical Machinery and Municipal & Civil‑Use Industries: In the metallurgical sector, it is used for storing rolling oils, coolants, and other materials; in mechanical machining, it stores cutting fluids and hydraulic oils; and in municipal applications, it serves as a secondary water‑storage tank for residential communities and office buildings, as well as a reservoir for heating hot water and fire‑fighting reserve water. It meets stringent requirements for safety, non‑toxicity, and leak‑proof sealing, making it suitable for a wide range of civil‑use and industrial auxiliary scenarios.

Material Advantages /Material Advantage
This product is manufactured from mainstream stainless steel grades such as 304, 316L, and 316Ti. Material selection is rigorously tailored to meet the specific requirements of various operating conditions. Its key advantages are as follows—without any exaggeration:
• Excellent corrosion resistance: 304 stainless steel, containing 18% chromium and 8% nickel, withstands weak acidic and alkaline solutions as well as storage in room‑temperature clean water, making it suitable for standard hygienic applications. 316L stainless steel builds on the 304 grade by adding molybdenum and limiting carbon content to ≤0.03%, significantly enhancing its corrosion resistance; it resists attack from seawater, highly concentrated acids and alkalis, and organic solvents, effectively preventing pitting and intergranular corrosion, and is ideal for harsh corrosive environments such as chemical processing and new energy applications. Meanwhile, 316Ti further optimizes high‑temperature and corrosion resistance, making it well suited to even more demanding storage conditions.
• Hygienic and Non‑Toxic Compliance: For applications in the food and pharmaceutical industries, cold‑rolled stainless steel sheets are selected, with surface roughness maintained at Ra ≤ 0.8 μm. After nitric acid or citric acid passivation, the material meets the requirements of GB 4806.9‑2016, the National Food Safety Standard, with heavy metal migration levels ≤ 0.01 mg/kg. It does not release harmful substances and does not react with stored materials, thereby preventing secondary contamination at its source and satisfying stringent cleanliness‑grade storage needs.
• Structural stability and durability: Stainless steel boasts high tensile strength and excellent toughness. Grade 304 stainless steel has a tensile strength of ≥515 MPa, while duplex grade 2205 achieves ≥620 MPa. These materials withstand extreme temperature conditions, with 304 offering a service temperature range of −270°C to 427°C and the 316 series spanning −196°C to 450°C. They resist deformation and aging, ensuring stable operation for 15–20 years under normal use without the need for frequent anti-corrosion treatments, thereby reducing long-term maintenance costs.
• Environmentally friendly and recyclable: Made from stainless steel, this product is 100% recyclable with no waste‑related pollution. Compared to storage tanks made from plastics or carbon steel, it aligns more closely with eco‑friendly principles, produces no harmful waste over long-term use, and meets the demands of green manufacturing.

Technological Advantages /Technical Advantage
Product manufacturing integrates mature manufacturing processes with a rigorous quality‑control system. Our core technological strengths lie in structural design, welding techniques, and functional compatibility, ensuring that our products are safe, practical, and easy to maintain.
• Structurally sound and compliant: The design strictly adheres to GB 150.1-2011 “Pressure Vessels—Part 1: General Requirements” as well as relevant industry-specific standards. Vertical storage tanks feature a variable‑thickness design, with bottom wall thickness ≥8 mm and top wall thickness ≥4 mm, balancing structural safety with material efficiency; verticality deviation is limited to ≤1‰ of the total height. Horizontal storage tanks are equipped with saddle supports, with support spacing precisely calculated based on bending moment analysis to prevent uneven loading and deformation. Customizable options include thermal insulation, heating, agitation, and liquid level monitoring, tailored to meet diverse process requirements.
• Exquisite and reliable welding technology: Utilizing high-precision welding processes, the tank body achieves seamless welds with weld strength exceeding 95% of the base material. All butt joints undergo 100% radiographic inspection, with a weld joint coefficient φ ≥ 0.85 and a weld toe height ≥ 1.2 times the tank wall thickness, effectively eliminating the risk of material leakage. Following welding, a specialized passivation treatment is applied to further enhance the tank’s corrosion resistance, extend its service life, and ensure suitability for demanding operating conditions such as high pressure and severe corrosivity.
• Excellent functional adaptability: Sterile-grade products feature mirror-polished inner walls with a surface roughness controlled at Ra ≤ 0.4 μm, and are equipped with an integrated CIP cleaning system that achieves a cleaning coverage of over 98%. Manholes adopt a quick‑open design, fully compliant with GMP sterility requirements. For agitated models, impeller types such as propeller or anchor can be selected based on the material’s viscosity; the agitator shaft is fitted with double‑ended mechanical seals to prevent media leakage and ensure uniform mixing. High‑pressure applications utilize duplex stainless steel construction and include a leak‑detection system; each unit undergoes rigorous hydrostatic testing prior to shipment to guarantee safe operation.
• Convenient and efficient operation and maintenance: The tank’s smooth, non-porous surface inhibits bacterial growth and prevents material residue. Routine cleaning is sufficient; frequent replacement of anti-corrosion coatings is unnecessary, resulting in annual maintenance costs of no more than 0.5% of the equipment’s original value. A modular design standardizes tank components, shortening customization lead times and simplifying transportation and installation. Moreover, the system can be flexibly adapted to site-specific conditions, reducing both installation complexity and ongoing operational challenges.
• Rigorous quality control: From raw material procurement to product shipment, we have established a comprehensive quality‑inspection system covering the entire production process. All raw materials comply with national standards such as GB/T 4237‑2015 and GB/T 3280‑2021. Prior to dispatch, products undergo multiple tests, including hydrostatic pressure and air‑tightness assessments, accompanied by standardized test reports, ensuring that each unit meets industry standards and user requirements while delivering long‑term, stable performance.
