ASTM A335 Alloy Steel Gr P5 Studded Fin Tube , Tubo Aletado
ASTM A335 Alloy Steel Gr. P5 Studed Fin Tube , Tubo Aletado
This page is about ASTM A335 Gr. P5 studed alloy steel fin tube, studed fin tubes with fin general material carbon / alloy / stainless steel , we sell these fin tubes more than 33 years and sell in over 70 countries.
YUHONG Group can make kinds of industry projects and supply variety of extruded fin tubes in industries. Our products are domestically sourced, developed, and produced, that means our customers have easy access to exactly the products they need for their particular application. Besides, we can make sure that you can get products with best quality and manufacturing standards and a local, concerned, customer service presence!
Studded Tubes produced by our company adopt resistance welding method and welding process is controlled by PLC program. Studded number can be set via the human-computer interface. Besides,the graduation parameter and compensating coefficient can be set according to technical requirements to ensure the quality and precision of products.Studded Tubes are applied to convection chamber of heating furnace in petrochemical industry for increasing the heat transfer coefficient at the fuming side and they are two or three times the square of light Tubes, because of the usage of studded Tubes, the hot strength can be got as the same as radiation in the reasonable design.
