Tubing System

The tubing system transports the material from the point of collection to the central unit. Dustcontrol has a very comprehensive assortment of tubing fittings and installation hardware. This gives greater flexibility in design and installation of our tubing systems. Our mechanical jointing system makes alterations and additions very easy to implement.

About Tubing System

The tubing system transports the material from the point of collection to the central unit. Dust is generally abrasive, some more than others, therefore the standard material thickness of the tubing system is
1.5 mm. Applications with fume and light dust use reinforced spiral duct. Stainless tubing systems and extra abrasion resistant fittings are available.Dustcontrol has a very comprehensive assortment of tubing fittings and installation hardware. This gives greater flexibility in design and installation of our tubing systems. Our mechanical jointing system makes alterations and additions very easy to implement.

Bends and branch pipes are designed to withstand high negative pressure. The bends are designed with a radial ridge to spread the impact area of the mateial thereby reducing wear and minimising the risk of blockage.

An effective tubing system has to meet certain requirements. Constant transport velocity in the tubing at different loads is one requirement. Correct transport velocity is another. When the velocity is too low, the material will cause a blockage. When the velocity is too high, this will lead to unnecessary wear and loss of energy. Dustcontrol can dimension the system to your needs.

Tubing System details

Steel Tubing

Our standard tubing system is of zinc coated carbon steel tubing and is used at 90 % of all Dustcontrol installations. Heavy wall thickness results in long life even in installations where considerable abrasion is present.

Stainless Steel Tubing

Stainless tubing is used with abrasive materials or because of hygienic considerations. When installed for material transportation, long radius bends should be used.

Reinforced Spiro Tubing

Spiro tubing is used most commonly for the connection of the central unit components, vacuum producer, filter unit and pre-separator. Spiro is not generally suitable for application with coarse and abrasive material but is commonly used in extraction systems for vapour, fume and light dust.

Mounting Hardware

Dustcontrol has a complete range of mounting hardware facilitating straightforward installation as well as changes.

Polymer Tubing System

When transporting material in a tubing system turbulent flow will cause noise. Material particles impact the hard tubing walls. Using an polymer (EPDM- and NBR-rubber) in bends, branch pipes and mounting brackets moderates the sound considerably. Every polymer bend and branch pipe are designed with a plugged hole that can be used for measuring and inspection.

Cones, branch pipes and bends are manufactured in EPDM- and NBRrubber. The components are abrasion resistant and sound absorbing.

*) In most systems, 76 mm should be selected as the smallest tube diameter. In systems where a small air-flow is desired or installation is more easily facilitated should 50 mm be used.
