how to calculate steel pipe travel speed on conveyor line

Determining steel pipe travel speed is an integral component of successful project execution, whether welding large diameter pipes or connecting them to conveyor lines. Travel speed determines how quickly your welder completes beads and thus, welding an entire pipe length will take. Many factors can influence this figure but most significantly will be skill level and working conditions of welder. On average, traveling at 140 inches of travel per hour allows an average welder to complete bead within four minutes.

Operational stability of a pipe belt depends on a range of factors, from equipment structural alignment and translation of requirements into specifications during its construction to maintenance procedures after startup and beyond. Failing or skipping maintenance procedures could trigger nonlinear effects that impede its functionality over its lifespan.

Uncontrolled rotation of pipe conveyor’s belt overlap can be caused by lateral forces exerted on it at its transition zone between curved flights and flat flights, including tension forces from tensioned and sagged belt sections, exerting forces whose magnitudes depend on geometry of that zone (such as its inclination and distance from molding rolls).

This instability of a conveyor system is also due to angular vibrations induced by interaction between transverse wave frequencies of the belt and excitation frequencies of hexagonal idler support assemblies. Resonances formed between these components result in zones with increased or decreased filling degrees on either edge, altering contact forces and producing twisting moments at certain belt speeds, leading to zone formation with zones of increased and decreased filling degrees that modify contact forces and produce twisting moments that favor twisting moments at certain belt speeds.

As well as being affected by lateral forces, excessive belt sag can also wreak havoc with the conveyor’s operational stability, particularly during straight flights. It could result in retracting of its cover which opens its edges enabling bulk material spillage or dust emissions from occurring.

Damage can also occur as a result of twisting belt overlaps, leading to decreased sealing effectiveness and external side damage that ultimately compromises belt durability and spillage of bulk material, creating safety risks in the conveyor system.

Uncontrolled rotation of a pipe conveyor’s belt may have secondary effects, including ghost misalignment (detectable only at low loads) between adjacent rollers. This condition is due to steel cord belts utilizing standard splices while fabric and aramid belts generally use finger splices; finger splices cause loss of torsional stiffness within joints which increase stress on twisted areas leading to ghost misalignment if left uncorrected; it can be addressed by replacing this type of splice with one with one with one which weld over time. This issue can be rectified by replacing it with one using standard welded splices.
