Frequently Asked Questions
-
Q: What is the difference between ASTM A179 and other heat exchanger tube standards like A214?
A: ASTM A179 is a cold-drawn seamless low-carbon steel tube specifically for heat exchangers, condensers, and similar heat transfer apparatus. It requires higher dimensional accuracy and smoother surface compared to A214. A179 is preferred when leak-proof performance and tight tolerances are critical. -
Q: Can you supply tubes larger than 2 inches?
A: Yes, we can produce tubes with outer diameters up to 4 inches upon request. For larger sizes, please consult our technical team to confirm availability and lead time. -
Q: What wall thicknesses are available for 0.5-2 inch tubes?
A: Common wall thicknesses range from 0.035 inch (0.889 mm) to 0.180 inch (4.572 mm). We can also manufacture non-standard thicknesses to meet your design specifications. -
Q: Are your tubes suitable for high-pressure applications?
A: Yes, seamless construction provides excellent pressure integrity. The exact working pressure depends on wall thickness and temperature. Our tubes are hydrostatically tested per ASTM A179 requirements (typically 1000 psi or as agreed). -
Q: Do you offer any heat treatment or surface coating?
A: Standard tubes are supplied in the as-drawn condition. We can also provide stress-relieved, annealed, or normalized tubes. Surface coatings such as epoxy or galvanizing are available as custom options. -
Q: How do you ensure the quality of each batch?
A: We implement ISO9001 procedures, including incoming material inspection, in-process dimensional checks, final hydrostatic/eddy current testing, and mechanical property verification. A mill test certificate is provided with each shipment. -
Q: What is the typical lead time for an order?
A: For standard sizes (0.5-2 inch) and common wall thicknesses, lead time is around 20–30 days after order confirmation. Custom sizes or special finishes may require 35–45 days depending on quantity. -
Q: Can I request samples before placing a bulk order?
A: Absolutely. We can provide sample pieces (typically 0.5m length) for your evaluation. Sample cost is subject to negotiation and can be deducted from your first order.
Trust Hemaokang Steel (Shandong) Co., Ltd. – with an annual export value exceeding US$50 million and ISO9001 certification, we have the capacity and expertise to fulfill your heat exchanger tube requirements reliably.
