SERRATED FIN TUBE FOR DRYING PLANT ASTM A335 P9 11CR HEAT TRANSFER
Manufacturing Process
1.Design the serrated fin tube, confirm the detailed parameter with the customers, which mainly includes the pipe length, OD, thickness, fin height, the number of fins within 1 meter and the serrate parameter.
2.Cutting the pipe to fixed length. Customers have different need with the fin tube length, so we need to cut the steel pipe into different length.
3.Split steel coil into steel strap. The height of fins is equal to the width of steel strap, so we need to cut the coil into the strap according to different fins height.
4.Then we need to punch on the strip,and Weld the steel strip on to the steel pipe.
We have one subsidiary, Function is as follow
