As a trusted manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory brings over two decades of metal fabrication expertise to produce high-quality Stainless Steel Buffer Tank 316L Material 2B Finish 500L Volume with Insulation. Our factory is renowned for precision engineering, rigorous quality control, and annual export value exceeding US$5 Million – US$10 Million. This buffer tank is designed to meet the demanding needs of HVAC, industrial process, and solar thermal systems, offering exceptional corrosion resistance, thermal efficiency, and long service life.

The tank is constructed from 316L stainless steel (low carbon grade) providing superior resistance to chlorides, acids, and aggressive media – ideal for coastal or chemical environments. The 2B finish (a smooth, matte, reflective surface) ensures easy cleaning, minimal crevice corrosion, and a hygienic appearance. With a generous 500-liter capacity and integrated insulation layer, this buffer tank effectively stabilizes system temperatures, reduces energy loss, and dampens pressure fluctuations, thereby improving overall system efficiency and extending equipment lifespan.

Key Features & Benefits:

316L Stainless Steel Construction – Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking; suitable for potable water, chemicals, and high-temp applications.
2B Surface Finish – Smooth, easy-to-clean surface reduces bacterial growth and maintenance downtime.
500L (0.5 m³) Volume – Ideal for medium-scale systems; compact footprint yet ample storage capacity.
High-Efficiency Insulation – Polyurethane foam or rock wool (optional) with thickness up to 80mm minimizes heat loss, saving energy costs.
Customizable Connections – Inlet/outlet size, flange standards (ANSI, DIN, JIS), and orientation tailored to your piping layout.
Durable Cladding (Optional) – Outer shell of stainless steel or aluminum for additional protection and aesthetic appeal.
Pressure & Temperature Ratings – Designed for typical working pressures up to 6 bar (higher available upon request); temperature range -20°C to +150°C.
Wide Application Range – Buffer storage in chilled water systems, hot water heating, solar thermal, heat pump systems, and industrial process tanks.

Frequently Asked Questions (FAQ):

Q: What is the main advantage of using 316L stainless steel over 304?
A: 316L contains molybdenum, which provides superior resistance to chlorides, acids, and pitting corrosion. It is ideal for seawater, chemical processes, and high-temperature applications where 304 may fail prematurely.
Q: Can the insulation be customized for extreme climates?
A: Yes, we offer polyurethane foam (PUF) or rock wool insulation with thicknesses from 50mm to 100mm. For very cold environments, we can increase insulation thickness or add a heating jacket option.
Q: What is the typical working pressure of this 500L tank?
A: Standard design is up to 6 bar. Higher pressure ratings (e.g., 10 bar, 16 bar) are available upon request with appropriate wall thickness adjustments.
Q: Do you provide certificates of material or quality?
A: Yes, we can provide material test certificates (MTC) for the 316L stainless steel, as well as welding procedure qualification records (WPQR) and pressure test reports upon request.
Q: How is the tank packed for export?
A: The tank is wrapped in protective plastic film, padded with foam, and placed in a wooden crate or steel frame for safe sea/air freight. Custom packaging options are available.
Q: Can I get a sample before bulk order?
A: Yes, we accept sample orders. However, due to the size of the 500L tank, we recommend starting with a small-scale prototype or a smaller capacity unit for testing.
Q: What is the lead time for a standard 500L buffer tank?
A: Typically 15–25 working days after order confirmation and deposit. For custom designs, please allow additional 5–10 days.
Q: Do you offer installation or technical support?
A: We provide technical documentation, installation drawings, and online support. For on-site installation, we can recommend local partners depending on your location.
