CSST Bonding: Me ke Nana? (Da Yadda Yake Mafi Kyau?)

Wani shine CSST Bonding?

CSST (Corrugated Stainless-Steel Tubing) bonding shine wata hanyar da mutum ya kula da mai zama da CSST metallic gas piping sannan ya kula da grounding electrode system don bayar da tarihi da yake da ita da ground. Ana amfani da CSST Bonding don dogara da iya da abin da za suka faru daga cikin systems masu shiga daidai a lokacin da inda ya faru da lightning strike a CSST gas pipe ko kuma a gaba.

Yana bukatar da CSST ya kula da grounding electrode system na electrical service na gidan da aka fadada CSST. Wannan tushen ya ba da hanyar da take da ita da stray voltage/current daidai zuwa ground.

Bonding na da kyau na CSST zai iya dogara da iya da abin da za suka faru ko damage a CSST gas pipe saboda lightning strike.

Daga Baka Yana Buƙata CSST Bonding?

Idan CSST an fada bila da ma ake sa ta daidai, akwai tasiri mai yawa da fire ko damage a gas lines idan ana faru lightning strike ko power surges a gaba.

Bayyana cewa lightning shine karamin alamun da ke faru, idan ana faru a gaba, zai iya haɗa a kan CSST gas pipe. Wannan energy ke faru zai iya haɗa zuwa metal na gaba da kuma kusa.

Idan CSST ba a kula daidai, farkon potential a bayan gas pipe da metal zai iya faru arc wanda zai iya dogara da damage a CSST gas pipe. Idan CSST ya dogara, zai iya tufi gas kuma zai iya faru fire ko explosion.

CSST bonding zai taimakawa a samun equipotential state a bayan CSST gas line da bonded metallic conductor. Saboda haka, CSST Bonding ya buƙata don dogara da iya da abin da za suka faru ko explosion saboda damaged gas lines a lokacin da power surges da lightning strikes. Tafinan da aka fada na nuna gas line da ya dogara saboda lightning strike.

Diagram na CSST Bonding

Don in kula da CSST daidai, ana fada separate bonding wire a kan rigid gas piping kafin CSST, ko kuma zuwa one of the CSST nuts. Tafinan da aka fada na nuna diagram na CSST bonding.

Tafinan da aka fada na nuna misal na CSST Bonding daidai.

Kode na CSST Bonding

CSST bonding, bonding conductor, grounding electrode system, bonding clamp, da kuma grounding conductor zai iya cikin kode. Za a iya hada da kowane babban.

A cikin National Fuel Gas Code, International Fuel Gas Code, da Uniform Plumbing Code, ana fada direct bonding don CSST gas piping systems for homes and buildings. Bonding na CSST zai iya canzawa electrification work kuma zai iya fada da kula da qualified electrical contractor da electrical inspector.

Bonding Conductor

Bonding conductor zai iya fada, protection, da kuma kula da grounding electrode system a cikin National Electrical Code, NFPA 70, da Canadian Electrical Code, CSA-C22.1.

Bonding conductor zai iya solid ko stranded aluminum or copper conductor. Girman bonding conductor ba zai iya fi ƙarin 6 AWG (American Wire Gauge) copper wire ko equivalent size of aluminum idan bonding conductor ya fada ne aluminum. Tafinan da aka fada na nuna misal na bonding conductor.

Bonding conductor ba zai iya fi ƙarin 75 feet (22860 MM) a cikin National Fuel Gas Code, International Fuel Gas Code, da Uniform Plumbing Code.

Bonding Clamp

Bonding clamp ba zai iya fada a kan corrugated stainless-steel tubing. Zai iya fada a cikin gas piping system a kowane wurin.

Wurin bonding clamp a cikin gas piping system zai iya zama saboda shortest bonding wire length zai iya karɓar da effectiveness of the direct-bond. Tafinan da aka fada na nuna misal na bonding clamp.
