Welded-Finned Pipes Tubes

Krystal  has been a leading manufacturer of custom finned pipe such as Welded-Finned Pipes Tubes for almost 60 years, serving the OEM and replacement markets.   We have full production capabilities, and can handle full runs for OEM components as well as short runs for replacement finned pipe.  Krystal specializes in manufacturing custom replacement welded fin pipes and can accommodate short lead times and expedited deliveries to minimize equipment downtime.
Our welded finned pipes are used in the power generation, petrochemical, oil refining industries and in industrial processing equipment and can be manufactured to meet ASME “U” and “S” stamp certifications.  All our finned pipes are custom-manufactured to meet the specific requirements of the application, whether they are for OEM equipment production or replacement parts.  Krystal  manufactures to the highest quality standards, ensuring a long product life with low maintenance for your equipment.

Our flexible production scheduling provides quick product turnaround, allowing you to minimize downtime during emergency repairs or scheduled downtime when ordering replacement parts, or to meet production schedules when ordering OEM parts.

We offer the following welded fin pipes:

1) HFRW Helical Serrated Finned Pipes:
HFRW Helical Serrated Finned Pipes –
High frequency serrated pipes are manufactured helically forming a segmented metal strip around a pipe.  The strip is welded to the pipe using high frequency electrical resistance welding (HFRW) during the forming process

2) HFRW Helical Non-Serrated (Solid) Finned Pipes:
HFRW Helical Non-Serrated (Solid) Finned Pipes
Non-Serrated finned pipes are used mainly for heat recovery equipment associated with boilers, gas turbines in power generation equipment and furnaces in petrochemical, refining and processing operations.

3) RSW Longitudinal Finned Pipes:
RSW Longitudinal Finned Pipes
Longitudinal finned pipes are used for heat transfer applications in the power generation, power recovery, petrochemical, oil & gas and industrial processing industries.

Krystal’s helical finned pipes are welded using high frequency electrical resistance welding (HFRW), producing a high-quality product in a wide range of metals. Our longitudinal finned pipes are manufactured using resistance spot welding (RSW).
