Qingdao Conqinphi Environmental Technology Group Co., Ltd. is a professional manufacturer with over 9 years of experience in fabricating high-performance heat exchangers. Our Stainless Steel Heat Exchanger with 40 tubes, 0.5mm thickness, 150°C max temperature, and 304L grade is designed to deliver reliable and efficient thermal transfer for demanding industrial applications. Built with precision engineering and rigorous quality control, this heat exchanger offers excellent corrosion resistance, compact design, and long service life – making it a trusted choice for heating, cooling, and condensing processes across multiple sectors.
The 304L stainless steel construction ensures superior resistance to intergranular corrosion, especially in welded sections, while the 0.5mm tube wall thickness balances heat transfer efficiency with mechanical strength. With 40 tubes arranged in a shell-and-tube configuration, the product provides a large heat transfer area within a compact footprint. It is suitable for applications such as HVAC systems, chemical processing, food and beverage production, pharmaceutical manufacturing, and oil refineries where hygiene and durability are critical.

Why Choose Our 304L Stainless Steel Heat Exchanger?
- Superior Corrosion Resistance: 304L grade withstands corrosive media, including acidic and chloride environments, extending equipment life.
- Enhanced Thermal Efficiency: Thin 0.5mm tube walls reduce thermal resistance, improving heat transfer coefficient by up to 15% compared to thicker walls.
- Low Maintenance: Smooth internal surfaces prevent fouling and scaling, reducing cleaning frequency and downtime.
- Customizable Design: Tube length, shell diameter, connection type, and baffle spacing can be tailored to match your process requirements.
- Rigorous Quality Control: Every unit undergoes hydrostatic pressure testing, dimensional inspection, and surface quality checks before shipment.
- Global Compliance: Our manufacturing facility is ISO9001, ISO14000, and OHSAS18001 certified, ensuring consistent quality and environmental responsibility.
This heat exchanger is widely used in industries such as chemical processing, food and beverage, pharmaceuticals, power generation, and HVAC. Typical applications include: cooling of process fluids, heating of water or oil, steam condensation, and heat recovery systems. The 40-tube configuration provides an ideal balance between capacity and footprint, suitable for skid-mounted systems and retrofit projects.

Frequently Asked Questions
-
What is the maximum operating temperature of this heat exchanger?
The standard design allows continuous operation up to 150°C. For higher temperature requirements, we can fabricate the unit using alternative materials or thicker tube walls. Please provide your specific process parameters for a customized solution. -
Can the tube thickness be increased for higher pressure applications?
Yes, the 0.5mm thickness is the standard option. Thicker walls (e.g., 0.6mm, 0.8mm) are available upon request to accommodate higher design pressures, though this may slightly reduce thermal efficiency. -
What certifications does your factory hold?
Our manufacturing facility is certified under ISO9001, ISO14000, OHSAS18001, HACCP, and several other management systems. Specific product certifications (e.g., ASME, PED) can be arranged at the customer's request. -
Can I customize the tube length or shell diameter?
Absolutely. We offer full customization of tube length (typically 500mm to 3000mm), shell diameter, baffle spacing, and connection types. Our engineering team will work with you to optimize the design for your space and performance needs. -
What maintenance is required for this heat exchanger?
Routine maintenance includes periodic inspection of seals, cleaning of tube surfaces to remove fouling, and checking for leaks. The 304L stainless steel construction resists corrosion, reducing the frequency of major overhauls. We recommend a cleaning schedule based on the fluid properties. -
What is the typical delivery time?
For standard configurations, delivery is usually 15–25 working days after order confirmation. Customized orders may require 25–40 working days, depending on complexity. We ship from Qingdao Port, China. -
Is this heat exchanger suitable for food-grade applications?
Yes, the 304L grade is food-safe and our optional electropolished surface finish meets sanitary standards (3A, EHEDG). We can provide a surface roughness of Ra ≤ 0.4 μm upon request. -
Do you provide thermal design calculations?
Yes, we offer free preliminary thermal sizing and can provide detailed simulation data for a nominal fee. Contact our sales team with your process conditions (flow rates, inlet/outlet temperatures, allowable pressure drop) to receive a proposal.
