Ii-FAQs

Yeyiphi imilomo yobhedu eyilungeleyo?

Ubhedu lugqwesa kwizicelo ezingabizi kakhulu kunye nobushushu obuphakathi kunye nokuvezwa kweekhemikhali. Ilungele iinkqubo zomlilo zikamasipala kunye nezakhiwo zorhwebo.

Kutheni ukhetha insimbi engenasici kwiindawo zaselwandle?

Intsimbi engatyiwayo iyamelana nokutyiwa kwamanzi etyuwa kangange-8–10x ubude kunobhedu. Uhlobo lwe-316SS lusisinyanzelo kwizicelo ezikude nonxweme ngokweNFPA 1962.

Kufuneka kutshintshwe kangaphi imilomo?

Ubhedu: iminyaka emi-5-7
Insimbi engenasici: iminyaka eyi-15 +
Ukuqhuba uhlolo lonyaka ukujonga ixesha lokutshintsha.

Ingaba ubhedu luyakwazi ukububamba ubugwebu?

Ewe, kodwa ugweme amagwebu anganyangekiyo ngotywala aqukethe iipolymers - ezi zikhawulezisa i-dezincification. Sebenzisa insimbi engenasici kwizicelo ze-AR-AFFF.

Ngaba imathiriyeli yombhobho iyawachaphazela amazinga okuqukuqela?

Ukhetho lwezinto eziphathekayo lunempembelelo kumazinga okhukuliseko kodwa hayi iimpawu zokuqukuqela kokuqala. I-1.5″ umlomo wobhedu kunye ne-stainless elingana iya kuba ne-GPM efanayo namanqaku xa intsha.
