Hapman’s Tubular Drag Conveyor transports materials from A to Z in a wide range of markets. With the ability to handle diverse material compositions, flow behaviors, and unique characteristics, this conveyor stands out among the rest.
Hapman’s TubePro™ Conveyor gently transports materials with en masse movement, reducing turbulence, wear, and energy use. Operating at low speeds with high torque, it minimizes product contact with pipe walls, reducing abrasion. Built to stop and restart fully loaded, it prevents waste and downtime, while the enclosed, dust-tight design safely handles dusty, toxic, or hazardous materials.
There are a dozen or so basic layouts but the customization of those, particularly to leg lengths and bend angles is practically limitless. This enables the Tubular Drag Conveyor to meet the unique demands of every layout. Our expert application engineers and designers will work with you to discover the most efficient layout for your specific needs.
Built to last, our conveyors are constructed using heavy Schedule 40 pipes—or Schedule 80 as an optional upgrade. This choice in material provides an exceptional lifespan against abrasion and deterioration that typically plagues thinner walled alternatives.
Continuous welding and an innovative offset of slotted round flanges forge a strong, interlocking pipe connection. This design not only ensures a secure, steadfast assembly but also contributes to the overall rigidity of the conveyor system. Each pipe connection has a stamped number, the numbers are shown on the layout drawing and help erect the conveyor.
Sealed pin chain is the most universally applicable as it is used for handling the widest range of material types, from gritty abrasives to food byproducts. Unlike open-architecture types, this heavy duty engineered chain utilizes sealing washers to keep material out of the articulating aspect of the chain, which can be extremely beneficial when handling certain products.
Our first choice for many applications, this rugged, dependable drag chain performs exceptionally well in situations where an open architecture chain can be applied.
Iron flights are one example of alternative flight types we offer, to overcome specific challenges such as elevated temperatures.
Uni-Seal chain is like sealed pin chain but with a universal link in place of the standard center link. This allows the chain to navigate between bends with short straight lengths of pipe.
Nearly all Tubular Drag manufacturers offer the Round-Link chain, most to the exclusion of all other chain types. The reason is primarily due to its availability and relatively low cost as compared to engineered chains. As logic would suggest, round-link chains have their limitations but, in some instances, a round-link chain is “good enough.” However, customers expect more from Hapman and we value that reputation, so we are far less likely to recommend it.
Our rounded gates conform to the pipe, which acts much like a bomb bay door, so there is no place for your material to become trapped.
An impact shoe assembly attached to the free end of the spring projects through a seal inside the conveyor and into proximity with passing flights (pucks). When energized, movement of the spring plate causes the impact shoe to reciprocate, striking the flights with enough frequency and amplitude to dislodge materials that may otherwise have a tendency to stick to the chain.
Often used in addition to chain hammers or air knives and usually at the last discharge points, brush boxes can provide an added measure of flight and chain cleaning to minimize problematic material build up and carryover. These have also been incorporated into schemes utilizing washing, rinsing, and deodorizing.
For some applications the layout of the conveyor, or the lack of maintenance availability, can create a scenario in which the conveyor’s chain tension is not monitored and adjusted as needed. This could create a potential problem. For this the answer is the Auto-Tensioner. This air-over-hydraulic automatic tension system provides consistent pressure to make sure that the chain is at its optimum tension. When it is time for manual intervention a notification will be sent to your main PLC.
As may be required by various plant equipment cleaning protocols, Hapman Tubular Drag Conveyors can be cleaned-in-place. This can be done in one of two ways. The first is that we can supply tubular drag conveyors which are CIP-ready, which is to say they are inclusive of all the features such as nozzles, supply valves, drain valves, isolation valves and connections necessary to integrate with an exciting CIP system. The second is a more comprehensive approach wherein Hapman also supplies the tanks, pumps, valves, and PLC controls.
Our in-house engineering team and panel shop supply standard configurations as well as custom packages for automation process optimization.
Our Performantee is a 100% operational guarantee that you will be fully satisfied with the performance of our equipment, and that it will achieve the specific results for which it was designed and manufactured. If not, we will revise or repair it to deliver the results we promised.
