Product Description

Longitudinal Finned Tube welding Process

Longitudinal Finned Tubes are produced by resistance welding fins in the longitudinal direction along the length of the tube,the fin strip is first formed into channel,such that each leg of the U will form a fin. The channeles are cut to the appropriate length and then oriented along the length of the tube and resistance welded in place. The length of the tube and resistance weled in place. The channels are welded in pairs, diametrically opposed-therefore the number of fins specified must always be a multiple of four.

For a given pipe or tube size, the desired heat transfer surface area per unit length of tube can be obtained by specifying the appropriate fin height and number of fins, the maximun number of fins is dependent upon the tube outside diameter-larger OD tube can accommodate a greater number of fins.

Production Capacity

Total two longitudinal type finning lines, monthly production capacity is 50 tons in total.

Codes and Standards

As per drawing and client’s protection

Surface Treatment and Protective

Each tube except stainless material will be polished by polishing machine to near white condition before welding, after welding, the finned tubes will be coated for transportation and site storage purpose, normally the coat will provide a period of 3 months prevention, and other coating material for longer prevention is also available as per client’s requirements.
