Tube Section Mill Rolls Dee Tee has a rich experience in designing of roll sets for a wide variety of tubular and open sections. To ensure complete precision and accuracy, the company employs expertise of latest COPRA software for designing. Profiling is done on high precision CNC lathes, giving high degree of accuracy. CNC wire-cut templates made out of SS are also available on request. These are generally required for re-profiling
Raw-Material – To give rolls durability and longer life, we recommend that the rolls are made out of AISI D3 (DIN 1.2080) or AISI D2 (DIN 1.2379). SAE 52100 may be used where the volumes are low and mill speeds are less. For the welding rolls, H13 (1.2344) is recommended as the temperatures are high. In high speed mills, rolls/welding shoes of bronze alloys are also used.
Range – We make roll sets for pipes up to 12” NB.
Fins- These are a vital component for tube making. Fin conditions the strip edges for proper welding. It gilds the edges of strip and squares the edges for butt welding. It also directs the tube to squeeze rolls for perfect welding. Fins should be wear resistant and tough. Best raw material for Fin is AISI-D2 (1.2379).
Tube Straightening Rolls
Tube Straightening Machine Rolls need complete precision since they are used in finishing stage of tube manufacturing. Dee Tee offers both single piece and Shrink Fitted Rolls. In case of Shrink Fitted Rolls, the shaft is generally made out of EN24 /EN19 material. The material of the rolls is mostly AISI D3 / D2 due to their high wear and impact resistance properties.
Rolls for Seamless Tubes | Tube/Section Mill Rolls
Dee Tee rolls are also used in the Seamless Tube manufacturing (through hot processing). It includes Push Bench Fixed and Adjustable Rolls, Stretch Reducing Mill Rolls etc. Due to high heat & heavy reduction case of push bench rolls, H10 (1.2365) material is used. For S.R.M. rolls, generally D2 (1.2379) or sometimes D3 is also used. Dee Tee also makes Piercing Bush which is generally in 1.2714 material.
