FAQ: Engineering & Procurement Guide

Q1: What basic information is required for a thermal calculation?

A: To provide an accurate design and quote, we need:

• Media Type: (e.g., Water to Oil, Steam to Water)

• Flow Rate: (m³/h or GPM)

• Temperature Profile: Inlet and required Outlet temperatures for both sides.

• Pressure Drop Limits: Maximum allowable pressure loss.

• Physical Space: Any dimensions constraints for installation.

Q2: How do I choose between a Plate Heat Exchanger (PHE) and a Shell & Tube Heat Exchanger?

A: It depends on your application:

• PHE: Best for high efficiency, compact space, and close temperature approaches (as small as 1°C). Ideal for HVAC and food industries.

• Shell & Tube: Best for high pressure (>25 bar), extreme temperatures, or fluids with large particles/high fouling. Ideal for heavy chemical and refinery processes.

Q3: What materials do you offer for corrosive environments?

A: We provide a wide range of materials to ensure longevity:

• Plates: SS304, SS316L, Titanium (for seawater), Hastelloy, and SMO254.

• Gaskets: NBR (standard), EPDM (high temp), and Viton (chemical resistant).

• Shells: Carbon Steel or Stainless Steel depending on your budget and fluid compatibility.

Q4: Are your heat exchangers compliant with international standards?

A: Yes. Our products are designed and manufactured following strict quality protocols. We can provide equipment compliant with ISO 9001, CE (PED), and we follow ASME design principles for pressure vessels to ensure safety and reliability in global markets.

Q5: What is the typical lead time for a customized unit?

A: Efficiency is our priority.

• Standard Plate Heat Exchangers: Usually 1-2 weeks.

• Custom Shell & Tube units: Depending on complexity and material availability, typically 4-6 weeks.

• Note: We offer expedited shipping options from our Jinan logistics hub to minimize your downtime.
