Introduction: - An
engineer has to perform different sorts of work involving pipes. Those works
involve hard work, experience, and knowledge at the same time. Here are some
instructions for the safety of man and materials. While installing the
butterfly valve, install an extension. This step is taken when installing a
valve directly to check the pump or valve. This safety step helps in preventing
discs of butterfly value from getting in contact with the check valve.
1. The valve must be
installed after completing all the welding operations. In the case of non-adhering
to these guidelines, it may be risky. When engineers notice that there is some
sort of blockage in the pipes, they do hydro jetting. Hydro jetting is
one of the safest and effective ways to clear blockages from pipes. It involves
a hose that is capable of exerting force through a continuous stream of water.
Any clogs or blockages in the pipe get clear. Only welding is not enough, The engineer has to do flange management so that future leakage could be prevented.
However, let the welding cool and then install the valve.
2. While doing welding
on the flange, remove the valve first. Doing welding on a flange when the valve
is intact is damaging for the valve. In some cases, you may need to change the
valve due to this human error. Pipes are meant for transporting many liquid or
gaseous items. Water is one of them that go from the water filtering plant to
home through pipes. An engineer should be more careful while doing repair work
on a water pipeline. After work, they must ensure that no welding residue,
scaling, dust, pipe waste is left inside the pipe. Clean the area with utmost
care because that water will pollute water and maybe damaging for people
drinking piped water. If required, an engineer may perform In-circuit test in pipes.
3. Many times, it is
required to blow air to remove any foreign matter in the pipe. In that case, an
engineer should install an extension tube in the place of the valve. This helps
in preventing damage to the seat ring. Engineers should use neutral detergent
or alcohol while removing rust or any waste materials from the pipe. Here, they
must ensure that detergent with harmful chemicals is not used in water pipeline
repair. Cleaning the surface of the flange is also important before
installation. Use compressed air on a flange to clean it.
4. Some flange comes in
zinc coating. Here the work of engineers increases. This type of flange is very
prone to leakage when proper care has not adhered to. This happens due to the
uneven surface of the flange. Valve and mounting flanges properly need an
alignment. Engineers should ensure that. Unless it is very much important,
engineers should not enter themselves into the pipes. In some circumstances, it
is very much needed to enter into the pipe to inspect or repair it. Here, the
safety team should ensure that a proper supply of air is maintained.
Conclusions: - Despite
following the instructions, accidents happen. An engineer may enroll him or her
in any online or offline course on first aid. Firstly, use Hydro
jetting for any blockage and still, it is not clear; an engineer may enter
into the pipe by following proper guidelines. If possible, an oxygen cylinder
may be mounted on the back of the engineer that will help in saving lives.
