How long does the repair plumbing?

plumber Chelsea plumber ChelseaMany 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.

Definiction of gaskets

Gaskets are mechanical seals, usually formed like a ring and used for sealing of flange joints.

In general, gaskets should not be reused.

Various types of gaskets are available depending upon their construction, materials, and features.

The following are the type of gaskets commonly used: Non-Metallic Gaskets (ASME B 16.21) Spiral-Wound Gaskets (ASME B 16.20) Ring Joint Gaskets (ASME B 16.20) Non-Metallic Gaskets are used with flat face or raised face flanges.

Spiral-Wound Gaskets are used with raised face flanges.
They are available with an inner ring and outer ring, which is also known as the cantering ring.
Ring Joint Gaskets are used with Ring Type Joint (RTJ) flanges.
They are available in octagonal or oval cross sections. A very high surface stress is developed between an RTJ gasket and the flange groove when RTJ is bolted up in a flange.
This leads to plastic deformation of the gasket. Thus, the hardness of the gasket is kept less than the hardness of the groove to achieve coining i.e.
bringing two metal surfaces of different hardness so tightly together that the softer surface deforms to match harder surface exactly in shape and finish.
Hence RTJ gaskets are not recommended for reuse.Źródło: https://en.wikipedia.org/wiki/Piping_and_plumbing_fitting

Pipes made of steel - Wikipedia

Galvanized steel potable water supply and distribution pipes are commonly found with nominal pipe sizes from 3?8 inch (9.5 mm) to 2 inches (51 mm).

It is rarely used today for new construction residential plumbing.

Steel pipe has National Pipe Thread (NPT) standard tapered male threads, which connect with female tapered threads on elbows, tees, couplers, valves, and other fittings. Galvanized steel (often known simply as "galv" or "iron" in the plumbing trade) is relatively expensive, and difficult to work with due to weight and requirement of a pipe threader. It remains in common use for repair of existing "galv" systems and to satisfy building code non-combustibility requirements typically found in hotels, apartment buildings and other commercial applications. It is also extremely durable and resistant to mechanical abuse.
Black lacquered steel pipe is the most widely used pipe material for fire sprinklers and natural gas. Most typical single family home systems won't require supply piping larger than 3?4 inch (19 mm) due to expense as well as steel piping's tendency to become obstructed from internal rusting and mineral deposits forming on the inside of the pipe over time once the internal galvanizing zinc coating has degraded.
In potable water distribution service, galvanized steel pipe has a service life of about 30 to 50 years, although it is not uncommon for it to be less in geographic areas with corrosive water contaminants.Źródło: https://en.wikipedia.org/wiki/Plumbing.
