Description du Produit

PIPEX
Bandes transporteuses textiles pour systèmes de transport tubulaires


PIFLEX
Bandes transporteuses avec carcasse métallique pour systèmes de transport tubulaires


Pipex et Piflex sont bandes transporteuses projetées pour systèmes de transport tubulaires équipées d’une carcasse textile o métallique, respectivement.
Notre savoir-faire dans l’étude, la conception et la méthode de production de cet innovant produit est le résultat de tests approfondis et appropriées évaluations théoriques et pratiques, qui ont permis de réaliser les bandes Pipex et Piflex, dont la caractéristique principale est une significatif flexibilité transversale.
Le système de transport tubulaire est étudié de façon que la bande puisse se fermer autour du matériau à transporter et le protéger pendant le transport. Pendant tout le parcours du transporteur, la forme des bandes tubulaires maintient la section circulaire grâce à la présence de rouleaux sur une structure appropriées, placées en forme hexagonale.
Cette bande retourne en forme plaine en correspondance des points de chargement, déchargement et passage près des poulies.
L’avant-garde dans la technologie du Pipex et Piflex pour systèmes de transport tubulaires inclut tous les avantages typiques des transporteurs avec mise en auge traditionnels, en ajoutant des bénéfices économiques autre que techniques et d’environnement.
Les problèmes de logistique et de protection environnementale non résolus dans le passé, peuvent être aisément surmontés aujourd’hui.


Les principaux avantages de cette technologie sont:
• Courbes horizontales et verticales à rayon court
• Dimensions transversales particulièrement compactes
• Dispersion du matériau transporté fortement réduite.
• Transport de matériau poussiéreux sans répercussions pour l’environnement
• Basse maintenance

Aplications Fields

Pipex and Piflex (Bande Transporteuse Caoutchouc) tubular conveyor belts are high technology products designed upon customers specific requests to properly work as per the operational characteristics of the plant where they will be installed.

The rubber covers quality is studied and developed to meet the specific needs of the conveyed materials.

The environmental regulations introduced in the last years require the industries to redraw the use of the plants for the transportation of dusty materials; the tubular belts plants are the most suitable to the handling of those materials where a special care to the environmental protection is needed (developed areas, parks etc.)

Some products affected by the presence of humidity, such as cement, meet in the tubular conveyor belt system the right technology for their transport in open areas such as loading and unloading wharfs.

PIPEX and PIFLEX give the maximum of their potential in the fields of:
• Cement factories
• Power plants
• Ports
• Steel factories


and any place where environmental impact must be reduced and/or where obstacles must be got round.

Design Details

Pipex et Piflex: Details

This page shows the layout of the main components of a tubular conveyor belt. Pulleys and take-up devices are the typical one of a standard troughing belt while the development of the plant is totally different because the belt, instead of leaning against the idlers, wraparounds by idler sextines placed perpendicularly to the belt and supported by purpose-made panels. As per the conventional troughing conveyor belts, it is worth to design the conveyor plant in accordance with the characteristics of the belt to adopt, especially keeping into consideration the modulus of elasticity of the carcass material.

From that derives transition lengths, bending radius as well as the take-up lengths. Where possible, depending on the centre-to-centre distance and the available space for take-up, it is recommended to adopt Pipex textile belts that, because of the reduced modulus of elasticity, allow short transition lengths and reduced bending radius. On the contrary, when the centre-to-centre distance requires an unacceptable take-up run, it is better to choose the Piflex tubular belt made of a steel carcass requiring wider transition lengths and bending radius.
A wrong evaluation of transition lengths and/or bending radius may cause an incorrect closure of the belt and its premature damaging.
To obtain a perfect performance it is furthermore essential to choose the pipe diameter keeping into consideration both the requested capacity and the size of the material; overfilled pipes or too big material lump sizes may determine an obstruction of the materials among the idlers and the damaging of both the belt and the steel structure.

Maximum curve angle for standard applications ß1 ≤ 45°

 

Minimum radius admitted
R ≥ 300 x tube diameter for Pipex textile belts
R ≥ 600 x tube diameter for Piflex steel carcass belts
For angles > 45° minimum radius must be gradually increased till the double at the maximum allowed angle of 90°. Special belt construction must be considered in order to bear the lateral compression.
