by Sagar Sharma on 2022-01-10
Certain types of sprinkler systems can also use plastic pipes. A testing agency is necessary to list the plastic pipe. CPVC (chlorinated polyvinyl chloride) and PB (polybutylene) are permitted plastic piping materials according to NFPA 13.
ISI Registration for Plugs and Sockets IS 1293: 2005
by Sagar Sharma on 2022-01-10
Electric equipment is connected to the alternating current (AC) mains electricity power supply in buildings and other locations via AC power plugs and sockets. Voltage and current ratings, shape, size, and connector type all change amongst electrical plugs and sockets.
ISI Registration for Polyethylene Pipes for Irrigation IS 12786:1989
by Sagar Sharma on 2022-01-10
Drip and mini sprinkler systems frequently use polyethylene irrigation pipe. These pipes are manufactured of high-grade virgin polyethylene and are highly resistant to UV radiation, chemicals, and agricultural fertilisers. The smooth inner surface of these pipes reduces frictional losses.
ISI Registration for Open Well Submersible Pump Set IS 14220: 2018
by Sagar Sharma on 2022-01-10
Open well submersible pumps are meant to be entirely submerged in water in open well applications. A single-stage pump with an impeller and a volute casing, or a multistage pump similar to borewell submersible pumps, can be used.
ISI Registration for Safety of Manual Metal Arc Welding of Carbon IS 814:2004
by Sagar Sharma on 2022-01-08
Carbon arc welding (CAW) is a procedure that involves heating metals with an arc between a non-consumable carbon (graphite) electrode and the work-piece to cause coalescence. It was the first arc-welding method to be devised, but it is no longer widely used due to the development of twin-carbon-arc welding and other modifications.
