Metal hoses, despite their 'heavy-duty' name, are in fact very fragile. The connection point between the corrugated tube and the fitting is particularly vulnerable to all kinds of stress. Therefore, when planning and/or installing the system, it is important to prevent: a. hose kinking - use a correct bend radius, bend restrictors or use angled [...]
Fittings are attached to metal hoses and ferrules by a special process such as TIG welding or, less frequently, brazing. The standard AF... solutions are described in our catalogue/website in the section Industrial Hoses - metal hoses. A bigger/smaller fitting can be joined with a steel hose via an additional reducer. Using seamless pipe elbows, [...]
What are the maximum operating parameters, including pressure and temperature, that metal hose assemblies can operate within?
Metal hose assemblies come in countless construction and material options so they can operate at actual operating parameters reaching very high values.The volume of transmitted pressure is determined by: nominal diameter, wall thickness of a source material, geometry of corrugations (pitch and height) and the number of braids. The same applies to the working temperature, [...]
The main difference between these hoses is their construction and application. Stripwound hoses („Peschel hoses”) are manufactured by winding profiled, metal strips that overlap each other. They are intended for the extraction of gases and fumes and transfer of bulk materials. Due to their construction, they are not pressure tight. They are usually attached to [...]
Tubes International offers precision ball valves with all types of actuators and needle valves with pneumatic actuators.
Tubes International offers a variety of valves, including ball valves, needle valves, check valves, safe-ty and metering valves.
Tubes International offers both ECE R110-approved valves for CNG and EC-79-approved valves for hydrogen.
Claw couplings (with the same claw distance) are connected by pressing two couplings against each other and rotating. The claws engage in the gaps in the claws of the opposite half.
Yes, it is. Before choosing the material, it is necessary to determine what medium these couplings will be used for. Standard coupling materials include zinc-plated cast iron, brass and stainless steel. In addition, the sealing material must be chosen: NBR or Viton.
The claw distance does matter, as there are different types of claw couplings. The most popular claw distance is 42mm, 41mm and 40mm (so-called GEKA couplings). Never join couplings with different claw distance.
