Pneumatic tubes polyamide MANURIL® PA11 & PA12, ABR, rigid - BBIO UNIVERSAL®

Flexible or semi-rigid MANURIL® tubes are made from rilsan® virgin polyamide.
This range is comprised of tubes in polyamide 12 (rilsan® A which appeared on the market in 1970) or in polyamide 11 (rilsan® B which apperaed in 1947) in the semi-rigid version (pa12phl or pa11phl) destined for pneumatic logics or for conveying miscellaneous fluids or in the rigid version (pa12hl) adapted to centralised lubrication with higher working pressures.
Rilsan® is a trade name of atochem.
This document contains abbreviations designating different mixtures of polyamides and that emanate from the DIN 73378 standard :

- P : plastified polyamide.
- H : stabilised polyamide for better resistance to temperature.
- L : stabilised polyamide for beter resistance to ultraviolet.
- I : modified polyamide for better impact resistance.
- Y : modified polyamide for better resistance to pressure.

MANURIL® tubes are guaranteed to be made from virgin pa12phl, a polyamide plastified and stabilised in temperature and light.
MANURIL® tubes are :
- Light and impervious.
- Very durable.
- Generators of low pressure losses.
- Resistant to abrasion and depression.
- Provided with good inertia even at low temperatures.
Polyamides 11 and 12 have good resistance to most chemicals at ambient
Temperature. a certain swelling may happen with aromatic hydrocarbons and alcohols without deteriorating the material. on the other hand, it does not resist very well to concentrated acids, phenols and other chlorinated solvents.
MANURIL® tubes are rigorously calibrated.
For certain dimensions, they are inconformity with NFE 49 100, DIN 74324 or DIN 74378 which define not only dimensional tolerances but also working pressures with safety factors, tests (aging, flexibility, impact resistance, etc...) for their correct use.
They are comprised of 100% virgin material, as required by DIN 74324.

Polyamide 12 (rilsan A) is a synthetic petrochemical product obtained from butadiene. with excellent characteristics, this material is more often used for the production of pneumatic tubing.
By consequence, it is available in many diameters and often in 7 colours (natural, black, white, blue, green, red, yellow).
They are obtained by calibrated extrusion.
Marking of the tubes is as follows : “tecalemit flexibles - part N° - manuril - din 73378 - pa12phl - ID x OD - batch N°”.
Admissible working temperatures of manuril tubes are from -40°C to +80°C.
In general, MANURIL® tubes are produced in long lengths on wooden reels.
They are then packed in sachets, boxes or on smaller capacity reels in multiples of 25 metre lengths.

Products according to specific requirements of din 74324, MANURIL® ABR polyamide tubes are intended for road trailer brake systems. their colour is black.
Tube marking is as follows : “tecalemit flexibles - part N° - manuril abr - din 74324 - pa 12 phl - ID x OD - batch N°”
Admissible working temperatures of MANURIL® ABR tubes are between - 40°C and +100°C, with the exception of diameters 10x1, 15x1.5 and 18x2 whose maximum working temperature is +60°C.
In general, MANURIL® ABR tubes are produced in long lengths on wooden reels. they are then repacked in sachets, boxes or on smaller capacity reels in multiples of 25 metre lengths.

Tubes made in this material are mainly destined to convey grease or oil under medium pressures.
The elastic modulus of this tube is roughly three times that of plastified polyamide but with very superior resistance to pressure.
Marking of tubes is as follows : “tecalemit flexibles - part N° - manuril - din 73378 - pa 12 hl - ID x OD - batch N°”
In general, MANURIL® pa 12 hl tubes are produced in long lengths on wooden reels. they are then repacked in sachets, boxes or on smaller capacity reels in multiples of 25 metre lengths.
Admissible working temperature of MANURIL®pa 12 hl tubes is between -40°C and +80°C.

Polyamide PA 11 (Rilsan® B) is of vegetable origin, coming from castor oil.
Apart from its environmental qualities, polyamide 11 has mechanical, physical and thermal properties superior to those of petrochemical derived polyamide 12.
Practically abandoned in the pneumatic tube industry for reasons of cost, it remains anappreciated alternative by some customers for specific tubes.
Marking of these tubes is as follows : “tecalemit flexibles - part N° - manuril - din 73378 - pa 11 phl - ID x OD - batch N°”
In general, MANURIL® PA 11 PHL tubes are produced in long lengths on wooden reels. they are then repacked in sachets, boxes or on reels of smaller capacity in multiples of 25 metres.
The admissible working temperature of MANURIL® PA 11 PHL tubes is betwwen - 40°C and +90°C..
