Can steam hoses be used for hot water?
Rubber hoses for steam can be used for hot water with a maximum temperature of about 90 ÷ 100ºC, unless otherwise stated by the manufacturer.
Are bellows of steel expansion joints manufactured as multi-layered?
The bellow of a steel expansion joint can be made as both multi-layer (most common) and single-layer (less common). The number of layers in a steel bellow depends on the parameters of the expansion joint, which include design pressure, temperature and value of design displacement. The multi-layer bellows can have from 2 up to 10 [...]
What materials are used to manufacture steel expansion joints?
Steel expansion joints can be made from a variety of steel alloys, depending on the conditions (pressure, temperature) in which they will operate and the type of medium that will flow through them. The working components of the expansion joints, i.e. bellows, are usually made of standard stainless steel and acid-resistant steel: 1.4541(ASI321), 1.4404(AISI316L), 1.4571(AISI316Ti) [...]
What types of displacement can steel expansion joints accommodate?
Depending on their design, steel expansion joints can accommodate movement in several directions: axial lateral angular along the axis of an expansion joint: compression or extension perpendicular to the longitudinal axis of an expansion joint displacing an expansion joint angularly from its longitudinal axis Obviously, in the actual operating conditions of a [...]
What are the maximum operating parameters including pressure and temperature that steel expansion joints can operate within?
Steel expansion joints come in countless design and material options, so they can operate at feasible operating parameters reaching very high values. When the expansion joints with multi-layer bellows are used, their working pressure may exceed 100 bar, depending on the expansion joint diameter. The same applies to the working temperature, which can even reach [...]
Can twin-ferrule fittings be used with pneumatic hoses?
Twin-ferrule fittings can be used with pneumatic hoses only if a 760LI reinforcing ferrule is fitted. There is also an option of fittings with PTFE compression ferrules, which can be used as an alternative to standard stainless steel compression ferrules on plastic hoses.
Are Hamlet LET-LOK fittings compatible with other brands of fittings?
LET-LOK fittings are interchangeable with Swagelok, Parker (A-LOK), DK-LOK, HY-LOK or Superlok products.
What materials are twin-ferrules fittings made of?
Twin-ferrule fittings are made of AISI 316 steel as standard, but we can also supply fittings made of: brass, Hastelloy C-276, Monel 400, 6Mo steel and Super Duplex on request.
Can instrumentation be used for CNG and hydrogen?
Tubes International offers ECE R110 and EC-79 approved fittings and valves that can be installed on both CNG and hydrogen-powered vehicles.
What tubes are used with instrumentation?
Typically, seamless tubes made of AISI 316/L steel according to AS™A213/A269 or similar standards are used with instrumentation. It is important for the tubes to meet these standards because of the quality of their finish and allowable tolerances, especially of the outer diameter. Tubes International supplies high quality HPS 1 tubes in standard bars with [...]
