TTP hose fittings Germany TTP model TTP price

TTP hose fittings are pipe fittings and pipeline connectors. Also known as tee fittings or three-way fittings, they are used where branch pipes diverge from the main pipeline. A tee is a chemical pipe fitting with three openings: one inlet and two outlets, or two inlets and one outlet. It comes in T shape and Y shape, with equal-diameter or reducing ports, used at junctions of three identical or different pipelines. The main function of a tee is to change the direction of fluid flow.

Advantages of TTP hose fittings

1. High joint strength: Based on the principle of cold work hardening of steel, the strength of straight threads rolled onto reinforcing bars is significantly increased, making the tensile strength of straight thread joints higher than that of the base material of the reinforcing bar. 2. Stable performance: The connection process is not affected by worker skill levels, ensuring stable performance. 3. Fast connection speed: Since off-site prefabrication and on-site assembly are used, reinforcing bars with pre-threaded ends can be mass-produced and stored at the rebar yard. When the construction schedule is tight, only additional assembly workers are needed at the site. 4. Wide application range: There are virtually no limitations in application; it is more suitable for scenarios where reinforcing bars cannot rotate, such as bent bars, fixed bars, and rebar cages. 5. Easy management: Mismatch between sleeves and reinforcing bars does not occur, and inspection is convenient. Operation is simple; ordinary workers can become proficient after a few hours of training. 6. Significant economic and social benefits: Shortens construction cycles, improves engineering quality, reduces energy consumption, facilitates environmental protection, reduces equipment investment, and has low additional costs, yielding clear economic and social benefits. 7. Low labor intensity: Processing one threaded end requires only a single step on a dedicated thread rolling machine.

TTP hose fitting selection

Metal hose fittings consist of a metal tube body, a stainless steel wire mesh braid, and fitting components. They can compensate for certain relative displacements and provide vibration damping and noise reduction. However, improper selection may not only fail to isolate vibration and reduce noise but also cause pipeline leaks or even equipment failure due to damage to the metal hose. Selection of metal hoses mainly involves the correct choice of parameters such as nominal diameter, connection type, working pressure, temperature correction, minimum bending radius, and hose length. Nominal diameter, connection type, and working pressure are directly determined by pipeline system requirements and generally pose no issues. Notably, when selecting the design pressure of the hose (which should be greater than the system working pressure), it should not be excessively high, because as the pressure-bearing capacity of the hose increases, its bending capability decreases significantly. Temperature correction and minimum bending radius are fixed for the product and provided by the manufacturer. Problems often arise in the selection of metal hose length. Excessive hose length can cause instability, increase flow resistance, and lead to additional mechanical damage and vibration issues. Insufficient hose length may fail to achieve compensation, vibration damping, and noise elimination, and may cause excessive bending stress, affecting service life.

TTP hose fitting selection criteria

1. Type and temperature of the fluid (please select quick couplings with body and sealing materials suitable for the fluid type and temperature). Depending on the fluid, suitable body and sealing materials vary. For example, for air, steel quick couplings are recommended; for water, choose brass or stainless steel. 2. Fluid pressure (please select quick couplings with pressure resistance suitable for the fluid pressure). Fluid pressure is also key to selecting quick couplings. Hydraulic quick couplings are standardized in the range of 5.0Mpa (51kgf/cm&²) to 68.6Mpa (700kgf/cm&²). Corresponding to pressure resistance characteristics, the structure of quick couplings also differs. 3. Structure of the automatic shut-off valve (please select quick couplings with valve structures suitable for piping applications). Valve structures include two-way shut-off, single-way shut-off, and two-way open types. Note that except for the two-way shut-off type, fluid will flow out from the piping upon disconnection. 4. Operating environment of the quick coupling (please select quick couplings with structures and materials suitable for the operating environment). Consider the humidity, dust conditions, and corrosiveness of the environment when selecting the type, body material, and sealing material of the quick coupling. 5. Ensure that the connection threads of the selected quick coupling are consistent. When using products from different brands, it is best to use male and female ends from the same brand. If cross-brand usage is necessary, consult the supplier's technical personnel before use to confirm compatibility. 6. Installation shape and dimensions. Determine the model and material of the quick coupling, and specify the assembly shape and dimensions corresponding to the piping characteristics. Note that dimensions are related to fluid flow rate.
