General Information EMP-3

THOMAFLUID^®-tubing screw joints are used for connecting flexible THOMAFLUID^®-tubing.

The connecting spigot is nearly cylindrical and dimensioned in such a way that dilatation of the tubing does not exceed 6 % (referring to the tubing outside diameter) even with unfavourable tolerances.

The tension of the remaining dilatation achieves tightness of the screw joint also without knurled nut (checked up to 6 bar).

The locking ring of the screw joints causes the arrestment of the tubing thus preventing effects of shear and torsion forces. Please note that of course the locking ring has to be left in place if the screw joint should be closed by a cover cap.

The elastic locking ring can be used repeatedly within the same screw joint, which means that the screw joint can be opened and tightly closed again using the same locking ring.

The locking ring is fitted with a flange serving as a stop. The tube can be pressed only to the point where the flange of the locking ring abuts to the body of the screw joint which causes an additional safety effect.

This safety effect is given by the fact that the screw joint remains tight even when the connecting spigot is teared off or heavily damaged by any impact. This tightness is caused by the knurled nut pressing in the locking ring into the cone of the screw joint thus producing a seal in the cone. The connecting spigot functions as a carrying bracket, and a carrying bracket has not necessarily to be a fixed component part of the screw joint body.

PP (Polypropylene)

Extremely good impact toughness and notch impact strength

Higher hardness and stiffness as well as better resilience than PE

Thermoforming possible

Very good dielectrical properties

Good resistance to alcohols, ketones, conc. acids and alkalis

Not stable to aromatic hydrocarbons, fats and oils, halogenes

Autoclavable

Resistant to hydrolysis

Physiologically safe

Colour: grey

Density: 0.90 g/cm³

Temperature range: +5 to +90 °C

Shore hardness D: 72°

Max. operating pressure: 10 bar at +20 °C

Water absorption: <0.05 %

Tensile strength: 25 - 40 N/mm²

Elongation at break: 800 %

Surface resistance: >10¹³ Ohm

Melt flow index MFR: 0.3 g/10 min.

PVDF (Polyvinylidene fluoride)

High-quality technical plastic for chemical apparatus and machine building, especially in the petrochemical, metallurgical, pharmaceutical, food processing, paper and textile industry as well as in the nuclear technology.

High impact toughness even at low temperatures

Good breakdown strength

Low dielectric loss factor

Highest mechanical stability and stiffness

Meeting highest purity requirements

Comply with the guidelines from FDA and USP class VI, additionally PVDF has the KTW approval. Up to +150 °C it is non-toxic and since it has a similar property to glass it is a no-culture medium for microorganisms.

Can be treated by autoclave (absolute sterile) and sterilized with gamma-rays without losing its mechanical qualities

Outstanding resistance to UV, weather and aging

Flame-resistant

High thermal stability

Resistant to alcohols, fats and oils, halogenes, alkalis, acids

Not stable to aromatic hydrocarbons, ketones, amines, pyridine, dimethylformamide, hot alkalis, fuming sulfuric acid
