Cross Pipe Connector made of PP, PVDF or PTFE
Product specification
Cross-shape, pipe connection at four sides
General Information
THOMAFLUID®-pipe screw fittings are used for connecting pipes made of various materials such as metal, glass or plastic e.g. PA, PTFE or PVDF. This represents a considerable advantage of this kind of screwed fittings. The screw fitting is not limited to use with rigid pipes but also with flexible pipes or tubing. In this case, carrying brackets (items 22036-54) are required.
THOMAFLUID®-pipe screw fittings of the MULTIFIT®-EMP-series can be screwed into THOMAFLUID®-valves, cocks, and flowmeters of the MULTIFIT®-EMP-series.
Assembly:
The connection principle entails pushing the pipe against the inner edge of the connector and sealing with a sealing ring. The pipe is secured in place by a cutting ring (PEEK), which is forced against the pipe by a nut. The more the nut is screwed onto the connector body, the more the slotted cutting ring wedges the pipe. The result is a tight, friction-locked connection, which can be released at any time. The design concept eliminates the dead volume. It also has no effect on the flow because the inside diameter is identical to that of the pipe.
If flexible tubing has have to be adapted using THOMAFLUID®-pipe screw fittings, first the carrying brackets have to be put in the flexible tubes. Afterwards, the fixed assembly is done by tightening the cap nut.
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
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
