Meanwhile, we comply with ASME Section IX standards to complete welding procedure qualification and welder qualification assessment, ensuring the welding quality and structural strength of vertical spherical storage tanks. Domestically, we strictly implement relevant standards such as GB 150-2011 “Pressure Vessels” and GB 50341-2014 “Code for Design of Vertical Cylindrical Steel Welded Oil Tanks”, optimize the design and fabrication details of vertical spherical storage tanks according to domestic site working conditions, medium characteristics and installation requirements, ensuring that products fit the practical needs of domestic engineering projects and achieving a high unity of customized production and standardized specifications, so that each vertical spherical storage tank meets safety and compliance requirements.

Combined with the core characteristics of vertical spherical storage tanks – efficient storage, stable structure and adaptability to diverse media, our products are precisely adapted to various industrial media. We fully optimize the tank structure, material configuration and sealing design of vertical spherical storage tanks considering the characteristics of different media to eliminate risks such as medium leakage, pollution and loss. The applicable storage media cover: petroleum media (crude oil, gasoline, diesel oil, fuel oil, etc.), some of which are volatile and flammable, and vertical spherical storage tanks can be customized with explosion-proof and anti-volatilization sealing structures to meet safe storage needs; chemical media (methanol, ethanol, sulfuric acid, liquid caustic soda, ethylene glycol, etc.), and according to different characteristics such as corrosiveness, flammability and explosiveness, vertical spherical storage tanks can be customized with anti-corrosion materials and protective structures to avoid tank corrosion; gas media (liquefied petroleum gas, natural gas, etc.), and vertical spherical storage tanks, with excellent pressure-bearing performance, can be customized with high-pressure adaptive structures to ensure the safe storage of gas media. At the same time, they can adapt to various neutral, corrosive and high-viscosity media, fully fitting the storage needs of different industries and demonstrating the diverse adaptability advantages of vertical spherical storage tanks.

In terms of process operation, we adhere to the principle of “standardized foundation + customized adaptation”. Centering on the structural characteristics of vertical spherical storage tanks, we can not only meet the stable operation of conventional working conditions but also flexibly customize the process parameters and operation modes of vertical spherical storage tanks according to customers’ actual production needs. Under conventional working conditions, the design pressure of vertical spherical storage tanks can be adapted from atmospheric pressure to medium and high pressure (customized according to medium characteristics), and the conventional design temperature ranges from -30℃ to 150℃. For extreme working conditions such as low temperature and high temperature, low-temperature toughness materials, thermal insulation or heat insulation systems can be customized to ensure the normal operation of vertical spherical storage tanks in various environments. The operation mode is mainly static storage, and various modes such as continuous feeding-intermittent discharging and circular storage can be customized. It is equipped with standardized process interfaces for feeding, discharging, liquid level monitoring, temperature monitoring, pressure regulation and emergency pressure relief, as well as safety components such as breathing valves, emergency relief valves, lightning protection and anti-static devices, liquid level alarm systems and fire-fighting supporting facilities. The safety configuration can be customized according to the project safety level of customers. After the fabrication and installation of all vertical spherical storage tanks are completed, they must pass all tests including appearance inspection, dimensional accuracy inspection, non-destructive welding testing (RT/UT/MT/PT), hydrostatic test and air tightness test before delivery, ensuring the safe, reliable, stable and efficient process operation of vertical spherical storage tanks.

As a source manufacturer, we have full flexibility and cost advantages in the selection of main materials for vertical spherical storage tanks. Combined with storage medium characteristics, process working conditions, site environment and customers’ cost budget, we achieve customized and precise selection, focusing on three key components of vertical spherical storage tanks: tank wall, tank bottom and head. The materials cover Q235B, Q345R (formerly 16MnR), 304 stainless steel, etc., ensuring the perfect adaptation of material properties to the structural requirements and application scenarios of vertical spherical storage tanks. As the core pressure-bearing component of vertical spherical storage tanks, the tank wall directly determines the structural strength and durability of the tank body. For conventional atmospheric pressure, non-corrosive/slightly corrosive medium scenarios, Q235B carbon steel (equivalent to ASTM A36) is selected, with a yield strength of ≥235MPa and tensile strength of 370~500MPa, featuring excellent weldability and outstanding cost performance, which can meet the use needs of conventional vertical spherical storage tanks; for medium and high pressure working conditions, low-temperature environments or scenarios with trace corrosive media, Q345R carbon steel (formerly 16MnR, equivalent to ASTM A516 Gr.70) is selected, with a yield strength of ≥345MPa, featuring better low-temperature toughness and structural strength, which can effectively improve the deformation resistance and impact resistance of vertical spherical storage tanks; for high-sulfur and highly corrosive media, high-purity media or coastal high-salt fog environments, 304 stainless steel (06Cr19Ni10, equivalent to ASTM A240 TP304) is selected, with a Cr content of ≥18% and Ni content of 8%~11%, featuring extremely strong corrosion resistance, which can eliminate medium pollution and tank corrosion problems and extend the service life of vertical spherical storage tanks.

The materials of the tank bottom and head of vertical spherical storage tanks are synchronously adapted to the tank wall materials to achieve customized selection and ensure the compatibility and stability of the overall structure. The tank bottom is in direct contact with the foundation. For conventional dry foundation environments and small and medium-sized vertical spherical storage tanks, Q235B carbon steel is selected, matched with anti-corrosion coatings to reduce corrosion risks; for large vertical spherical storage tanks, soft soil foundations or easy settlement scenarios, Q345R carbon steel is selected to improve the deformation resistance and settlement resistance of the tank bottom and avoid tank bottom cracking and leakage; for wet corrosive foundations or highly corrosive medium storage scenarios, 304 stainless steel is selected to fundamentally eliminate tank bottom corrosion and leakage problems. As a sealing and pressure-bearing auxiliary component of vertical spherical storage tanks, the head is made of the same material as the tank wall. Under conventional working conditions, Q235B or Q345R is selected to ensure welding compatibility and structural stability; under strong corrosion working conditions, it is upgraded to 304 stainless steel, equipped with anti-corrosion sealing structures to further enhance the anti-corrosion and anti-leakage capabilities of vertical spherical storage tanks, fully realizing the precise matching of material properties and customized scenarios of vertical spherical storage tanks.
