Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in high-quality metal products. With an annual export value of US$5 million to US$10 million and a global reach covering North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and more, we are proud to introduce our 316L Stainless Steel High-Pressure Heat Exchanger Pillow Plates. These plates are engineered to deliver exceptional corrosion resistance, mechanical strength, and thermal efficiency in demanding industrial applications. With a thickness of 2.5mm and a working pressure rating of 10 Bar, they are ideal for high-pressure heat transfer systems where reliability and longevity are paramount.
Our pillow plates are manufactured using advanced embossing and welding techniques, creating a dimple pattern that maximizes surface area for optimal heat exchange while maintaining structural integrity under pressure. The use of 316L stainless steel ensures excellent resistance to pitting and crevice corrosion, even in chloride-rich environments, making these plates suitable for chemical processing, food & beverage, pharmaceutical, and HVAC industries. Each plate is subjected to rigorous quality control to ensure consistent performance and dimensional accuracy.
Key Features & Technical Specifications
- Superior Material: 316L stainless steel offers enhanced corrosion resistance compared to 304, especially in acidic or saline environments.
- Robust Thickness: 2.5mm plate thickness provides excellent strength for high-pressure applications without adding excessive weight.
- High Pressure Rating: Designed to withstand up to 10 Bar working pressure, suitable for many industrial heat exchange processes.
- Efficient Heat Transfer: The unique pillow (dimple) pattern increases turbulence and surface area, improving thermal efficiency by up to 20% compared to flat plates.
- Customizable Dimensions: Length, width, and pattern geometry can be tailored to your specific equipment requirements.
- Versatile Connections: Plates can be supplied with pre-drilled holes, threaded ports, or welded nozzles as per your design.
- Surface Finish Options: Choose from 2B (bright), BA (bright annealed), or matte finish to suit hygiene or aesthetic needs.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 316L and 304 stainless steel for pillow plates?
A: 316L contains molybdenum, which provides superior resistance to pitting and crevice corrosion, especially in chloride or acidic environments. It is preferred for high-pressure and corrosive applications. -
Q: Can you guarantee the 10 Bar working pressure?
A: Yes, our plates are designed and tested to withstand a maximum working pressure of 10 Bar at room temperature. For higher pressures, we can discuss custom designs. -
Q: Do you offer custom sizes?
A: Absolutely. We can customize length, width, thickness, dimple pattern, and connection ports based on your drawings or specifications. -
Q: What is the typical lead time?
A: Lead time depends on quantity and complexity. Standard sizes typically ship within 20–30 days after order confirmation. Custom orders may require 30–45 days. -
Q: What surface finishes are available?
A: We offer 2B (bright), BA (bright annealed), and matte/brushed finishes. For food-grade applications, a 2B or BA finish is recommended for easy cleaning. -
Q: How do you ensure the quality of the welds?
A: All welds are performed by certified welders using automated TIG or laser welding. We conduct 100% visual inspection and leak testing (hydrostatic or pneumatic) before shipment. -
Q: Can these plates be used for both heating and cooling?
A: Yes, they are suitable for both heating (steam, hot water, thermal oil) and cooling (chilled water, brine, refrigerants) applications, as long as the media is compatible with 316L. -
Q: What is the packaging method for export?
A: Plates are packed in wooden crates or steel frames with foam padding to prevent damage during transit. We can also customize packaging per your request.
