Accident prevention hydraulics
Everyone knows perfectly well that it is much better to prevent failures hydraulics rather than repair them. To that just might be, it is the right approach to these issues and the efficient use of hydraulic installations, so you should find out what it is. First of all, at the beginning we should take care to choose a good system, a proven company and its installation to hire professionals. Later you need to be more regular periodic reviews and monitor the status of pipes and other parts of the system, and if you get even a small problem, it is always worth call a specialist, who immediately take care of him. Thus we avoid serious accidents which repair is often very expensive.
Pipes - worth to know
Pipes are commonly joined by welding, using threaded pipe and fittings; sealing the connection with a pipe thread compound, Polytetrafluoroethylene (PTFE) Thread seal tape, oakum, or PTFE string, or by using a mechanical coupling. Process piping is usually joined by welding using a TIG or MIG process. The most common process pipe joint is the butt weld. The ends of pipe to be welded must have a certain weld preparation called an End Weld Prep (EWP) which is typically at an angle of 37.5 degrees to accommodate the filler weld metal. The most common pipe thread in North America is the National Pipe Thread (NPT) or the Dryseal (NPTF) version. Other pipe threads include the British standard pipe thread (BSPT), the garden hose thread (GHT), and the fire hose coupling (NST).
Copper pipes are typically joined by soldering, brazing, compression fittings, flaring, or crimping. Plastic pipes may be joined by solvent welding, heat fusion, or elastomeric sealing.
If frequent disconnection will be required, gasketed pipe flanges or union fittings provide better reliability than threads. Some thin-walled pipes of ductile material, such as the smaller copper or flexible plastic water pipes found in homes for ice makers and humidifiers, for example, may be joined with compression fittings.
Underground pipe typically uses a "push-on" gasket style of pipe that compresses a gasket into a space formed between the two adjoining pieces. Push-on joints are available on most types of pipe. A pipe joint lubricant must be used in the assembly of the pipe. Under buried conditions, gasket-joint pipes allow for lateral movement due to soil shifting as well as expansion/contraction due to temperature differentials.11 Plastic MDPE and HDPE gas and water pipes are also often joined with Electrofusion fittings.
Large above ground pipe typically uses a flanged joint, which is generally available in ductile iron pipe and some others. It is a gasket style where the flanges of the adjoining pipes are bolted together, compressing the gasket into a space between the pipe.
Mechanical grooved couplings or Victaulic joints are also frequently used for frequent disassembly and assembly. Developed in the 1920s, these mechanical grooved couplings can operate up to 120 pounds per square inch (830 kPa) working pressures and available in materials to match the pipe grade. Another type of mechanical coupling is a Swagelok brand fitting; this type of compression fitting is typically used on small tubing under 0.75 inches (19 mm) in diameter.
When pipes join in chambers where other components are needed for the management of the network (such as valves or gauges), dismantling joints are generally used, in order to make mounting/dismounting easier.
Czy prace hydrauliczne trwają długo?
Many people avoid replacement of hydraulic and maintenance and minor repairs, because they do not have time for it to be organized. Often it seems to us that such work take a long time and cause discomfort, but hardly anyone takes into account how much damage and problems may arise from malfunction or failure of the hydraulic system. Periodic maintenance or minor repairs does not take much time, and if you know exactly where you are located pipes and other parts of the hydraulics, everything runs more smoothly. So let's spend these few hours and invite home to professional, because in this way we will be able to avoid additional high costs and other problems.
