I-API5 yentsimbi yentsimbi yentsimbi ye-API5L yi-GRB yindawo eqhelekileyo yentsimbi esetyenziswayo, isetyenziswa ngokubanzi kwioyile, igesi kunye namanye amashishini. "I-Aphi5l" yayo "ngumgangatho ophuhliswe yiZiko lePetroleum yaseMelika, kunye" ne-GRB ​​"libonisa inqanaba kunye nohlobo lwezinto ezisetyenziswayo, ezihlala zisetyenziselwa imibhobho yoxinzelelo. Inzuzo yemibhobho yentsimbi engenamthungo ilele kwiipropathi zabo ezintle kunye nokunganyangeki, kwaye zinokusebenza ngokugqibeleleyo kwiindawo ezinobushushu kunye nengcinezelo ephezulu.

Izinto eziphambili zekhemikhali ze-API5l GRB zentsimbi zibandakanya ikharbon, i-manganese, i-phosfurus, phosfurus, kwaye zinokwanela iplastiki kunye neplastiki emva kwenkqubo engqongqo kunye neplastiki emva kwenkqubo enobushushu onyango. Olu hlobo lombhobho wentsimbi uhlala usetyenziselwa ukuthutha ulwelo kunye neegesi, ngakumbi ekuxhaphazeni nasekuhambiseni iintsika zeoyile negesi, ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle.

I-ASTM A53, I-ASTM A106kwayeAPI 5Lyimigangatho yeentsimbi eziqhelekileyo zentsimbi, nganye efanelekileyo kwiimeko ezahlukeneyo zesicelo.

Umgangatho we-ASTM A53 usebenzisa ikakhulu kwimihlaba efana namandla, ukwakhiwa kunye nepetrochemicals. Umbhobho wentsimbi walo mgangatho ulungele uxinzelelo olusezantsi kunye neemeko zobushushu eziphantsi, kwaye ihlala isetyenziselwa ukuthutha amanzi, igesi kunye nolunye ulwelo. Inamandla amahle kunye nokwabelana, kwaye kufanelekile ukwenza imibhobho eyahlukeneyo kunye nezakhiwo.

Umgangatho we-ASTM A106 ugxile ngakumbi kubushushu obuphezulu kunye nezicelo zoxinzelelo oluphezulu kwaye zilungele umzi-mveliso weoyile negesi. Imibhobho yentsimbi engenamthungo yalo mgangatho isetyenziselwa ikakhulu ukuthutha i-Steam, amanzi ashushu kunye neoyile. Banokugcina iipropathi ezintle kumaqondo obushushu aphezulu ukuqinisekisa ukhuseleko kunye nozinzo lombhobho.

Umgangatho we-API 5L yenzelwe ishishini leoyile negesi kwaye ilungele imibhobho yoxinzelelo oluphezulu. Imibhobho yentsimbi engenamthungo ehlangabezana nalo mgangatho igqibelele ukunganyangeki koxinzelelo kunye nokunganyangeki koxinzelelo, ukuqinisekisa ukusebenza okukhuselekileyo phantsi kweemeko ezikhuselekileyo. Imibhobho ye-API ye-5l ihlala isetyenziswa ekuxhaphazeni nasekuhambiseni kweendawo zeoyile negesi ukuqinisekisa ukuthutha ngokufanelekileyo kolwelo.

Le migangatho mithathu yemibhobho yentsimbi engenamthungo ineempawu zazo, ezigubungela iimeko ezahlukeneyo zesicelo ukusuka kuxinzelelo oluphezulu, ukusuka kubushushu obuphakathi ukuya kwi-Deceds ePhakamileyo, kunye nokubonelela ngempumelelo yokhuseleko kunye nokusebenza kakuhle.
