Heat Exchanger

A: Your order will be processed right after the deposit is received in our bank. Equipment production normally takes 10-20 days depending on available inventory. If you have an urgent order, please contact us at +86 181 5720 5136. We will gather all the resources and check the possibility of fast production to provide clear feedback.

A: The wooden crates are used for transportation, which act as protective packaging during transportation, especially when products from multiple manufacturers are consolidated into one container for LCL transportation. This method can maximize their integrity.

A: 30% deposit in advance, 70% balance against the copy of B/L. T/T, Trade Assurance, Paypal, Western Union, Credit Card, L/C etc.

A: If you need to revise the product design or specification of cryogenic equipment, please let us know as soon as possible. We will work with you to understand the changes you require and provide a new design or specification that meets the need. Please keep in mind that depending on the extent of the revisions may impact the delivery timeline or pricing of the product.

A: If you need to cancel an order, please inform us as soon as possible. It's important to note that our production process begins immediately after we receive the deposit in our bank account. We have a buffer period of 1 or 2 days for returning the payment, which normally takes 1 or 2 days to get into our bank account. However, once the production has started, cancellation may not be possible and may result in cancellation fees or forfeiture of the deposit.
We understand that unexpected circumstances may arise, and we will work with you to find the best solution. If you need to cancel your order, please contact us as soon as possible and provide the reason for cancellation. We will do our best to accommodate your needs while minimizing any impact on production timelines or costs.

A: Increase the shell-side design pressure up to 10/13 of the tube-side design pressure. (The logic behind this “10/13” rule is that the hydrotest is done, as per ASME, at 1.3-times the design pressure—it was popularly known as the ⅔ rule based on old code hydrotest pressure before the year 2000).

A: Check the tubes, noting any damage and replace if needed. Clean the heat transfer area. Flush heat exchanger: eliminate and clean debris and buildup (check asset user guide or warranty manual for recommended chemicals) Inspect relief valves.

A: One common method for sizing heat exchangers is the “rule of thumb,” which suggests using a surface area of 1.5 to 2 times the heat transfer area. However, this method may not be accurate for all applications and can result in oversizing or undersizing the heat exchanger.

A: Without enough airflow to carry heat away, the heat exchanger overheats in excess of safe operating temperatures. Such overheating can cause premature metal fatigue and lead to stress cracks throughout the heat exchanger.
