·Yiyi's sales and service team will be committed to providing you with quality services throughout the process to ensure that your needs can be met to the greatest extent. For example: we have salesmen who are proficient in business and insist on one-to-one service, which ensures that all your questions can be responded to in the shortest time; we have a strong design department that can design 2D, 3D and simulated dynamic simulation diagrams according to your needs, so that you can verify all your ideas before delivery.
·Yiyi has a wealth of overseas transporter resources and can provide you with transportation services such as sea, land and air transportation; strong import and export trade capabilities, and can also assist you in passing customs to ensure that your goods enter your country smoothly. We have installation technicians in some countries around the world who can provide you with installation technical services on site. If your country is not within the scope of on-site installation services, we will still provide you with online technical guidance throughout the process until they are successfully started and run.

We provide integrated coordination and management for all procurement needs, covering design, production, delivery, installation, startup, and commissioning to achieve optimal stainless steel equipment solutions. Yiyi’s project management team serves as the single point of responsibility for technical, financial, and commercial coordination, reducing the burden of multi-supplier management. Our turnkey engineers mitigate inherent project risks, including performance, cost, and timeline objectives. Depending on your needs, Yiyi can manage specific or all aspects of your system’s design and development.

·All designs adhere to industry standards and specific operational requirements. Key references include GB 150 Pressure Vessels and ASME VIII standards. The design must account for the corrosiveness, temperature, and pressure range of the working medium, as well as whether mixing or heating is required. Materials such as 304 or 316L stainless steel are selected based on the pressure and medium, with typical pressure vessels using thicknesses of 5–10 mm.
·Structural designs may include vertical, horizontal, or cylindrical tanks. Process designs can incorporate mixing systems and jacketed structures as needed, with high-quality argon arc welding to ensure durability and corrosion resistance. Safety equipment such as relief valves, pressure gauges, and efficient venting and drainage systems are essential. Polishing and acid passivation treatments enhance the surface finish and corrosion resistance.
·Inspection processes include hydrostatic or pneumatic testing and non-destructive methods such as X-ray inspection to ensure safety and reliability. For tanks used in the food or pharmaceutical industries, cleaning verification follows GMP or FDA standards.

·Producing custom stainless steel tanks requires various key components to ensure reliable connections, functionality, and safety. Connection and sealing components include welding flanges (slip-on, butt-weld, and blind flanges), meeting GB/T or ASME standards for connecting pipes and tanks. Sealants like PTFE and rubber gaskets are suitable for corrosion-resistant environments, while mechanical seals prevent leaks in rotating parts, such as mixer shafts. Bolts and nuts are made from stainless steel and comply with DIN standards to ensure strength and corrosion resistance.
·In functional components, mixers are selected based on the medium’s viscosity, with options such as ribbon, anchor, or frame agitators. Shafts require mechanical seals to prevent leakage. Jackets, either full or half-pipe, are available for steam or cooling water circulation, while insulation materials like rock wool or polyurethane minimize heat loss. Spray cleaning balls support CIP cleaning systems in food and pharmaceutical applications.
·Safety and monitoring components include spring-loaded or relief safety valves to prevent overpressure, along with pressure gauges and thermometers for real-time monitoring. Liquid level gauges can be magnetic, glass tube, or ultrasonic, and explosion-proof devices like valves or membranes are available if needed.
·Piping and valve components include elbows, tees, and reducers made from materials matching the tank to ensure system integrity. Common valves like ball, butterfly, and globe valves are selected based on the medium, with sanitary-grade valves used in food industries.
·For electrical and automation components, motors and frequency converters regulate mixer speeds, while PLC systems automate heating, cooling, and mixing processes. Sensors monitor temperature, pressure, and liquid levels, providing feedback for operational control.
·Additional accessories include standard manholes with a diameter of around 500 mm for inspection, cleaning, or observation, along with drain and vent ports positioned at the tank's base and top for thorough emptying. Ladders and guardrails on large vertical tanks facilitate safe maintenance operations.

·Short-term/long-term maintenance contracts
