Sugar Mill Tube Expanders
Primary use of sugar mill tube expanders is for rolling thin-walled tubes in sugar mill juice heaters and evaporator pans. As with three roll systems and thin-walled tubes, expanders for sugar mills give a more concentric, uniform expansion and eliminate triangulation. Juice pans can be one of the most awkward tubular vessels to retube. The SB Series Sugar Mill tube Expanders make the job much easier when used with the CSB expander. Covering tube OD from 1.1/2″ to 4.1/2″ and rolling with a 5-roll system, these expanders give smooth, consistent rolls in the sugar mill apparatus.
We make the CSB Series sugar mill tube expanders to the sizes you require The CSB series rolls the bottom plate and the SB series rolls the top. To achieve an accurate roll, measurements between the two plates are required. The CSB series when operated from the top when minimal space availability underneath the juice pans, allowing for its operation.
In the diagram above the picture represents a juice pan with the SB Series (1) and CSB Series (2) tube expanders and how they would be operated from above as rolling these tubes from the bottom is very restricted. Tube sheet thickness is covered in sizes 1.1/4″, 1.1/2″ and 2.0″.
Product Quality
We work to high tolerances for all machining of expanders and associated equipment. This allows accurate expansion to achieve perfect sealed joints in tube sheets. Using the best tool steel and cryogenic processes for hardening and conditioning. Giving our tooling the optimum performance in the harshest surroundings.
We assemble each expander while checking the quality of the manufacture. Every individual tool is laser-marked with our name, Powermaster Canada. Also, we mark with the tube OD, wall thickness and expansion range. Expanders are then oiled bagged and boxed for shipping. Therefore, with our quality control and machining excellence, we supply a quality tool.
Rolling Sugar Mill Expanders
When rolling sugar mill expanders the PTR-03 is the ideal power source. In either 120 or 240-volt configuration, these rolling motors provide all the power needed. Each unit is supplied with the correct Mandrel Drive. The mandrel drive connects to the unit via a Morse Taper 3 connection. The expanders fit the other by a 3/4″ female square. As shown below.
