Each batch of pipes is sampled and tested, and records are kept as a quality guarantee for the final product.}

^{Product Description}

^{The main design feature of Embedded Fin tubes involves the fin being inserted and welded into a helical groove cut into the tubes. G fins can be used in higher temperatures and are very durable. Embedded fins are best suited for use in high thermal cycling or high temperatures and where the fin side will be subjected to regular cleaning. This type of fin comes with a major limitation being the need for a minimum wall thickness of 1.65mm to accommodate the grooves. However, the ‘G’ type fin can withstand temperatures of up to 400°C and can incorporate carbon steel fins for better conductivity.}

G Finned Tube Manufacturing Process

^{Fin strip is rolled in a uniform taper, helically wound into a plowed groove into the tube wall}

^{and simultaneously backfilled (by flat rotating discs) on both sides to lock the fin to the tube.}

^{No tube material is removed. This gives an excellent bond with high pull out loads.}

^{Fin Material: Aluminium/Copper/Carbon Steel.}

^{Core Tube Material: Carbon Steel/ Carbon Alloy Steel/Stainless Steel/ Nickel Alloys/Copper/Copper Alloys.}

^{G Finned Tube Properties}

^{Core Tube: Carbon steels (ASTM A 179/ A 214, St 35.8,etc.), low-alloy steels, stainless steels, copper-nickel alloys, aluminum bronze, copper, nickel-alloys(Alloy 400, ext.),}

^{Fins:Aluminum ASTM B209 Al 1060;ASTM B209 Al 1100, A1050, etc.}

^{Maximum operating temperature for this fin type is 450°C.}

^{G type embedded fin tubes machine is designed based on international advanced technologies and experience with stable and firm slotting embedding technology, pulled off force not less than 70 N, medium allowable temperature of 450 ℃, with strong resistant and heat-resistant ability, widely used in the impact of petrochemical refining air condenser.}
