Kwintsimi yoshishino yanamhlanje, iibhobho zetsimbi zisetyenziselwa uluhlu olubanzi lwezicelo kunye neentlobo ezininzi, ezikhazimulayo. Phakathi kwabo, i-ASTM A106 / A53 / API 5L GR.B ibakala B lensimbi, njengento ebalulekileyo yepayipi yensimbi, ithandwa ngabanjineli kunye nabavelisi ngokusebenza kwayo okugqwesileyo kunye noluhlu olubanzi lwezicelo.

Okokuqala, makhe sijonge kwiimpawu ezisisiseko zeI-ASTM A106/A53/API 5L GR.Bibakala lensimbi B. Le mpahla yombhobho yensimbi iqulunqwe ikakhulu ngezinto ezifana nekhabhoni, i-manganese, i-phosphorus kunye nesalfure, kwaye ineempawu ezintle zoomatshini kunye neempawu ze-welding. Iimpawu zayo eziphambili ezinjengokuqina kokuqina, amandla esivuno kunye nobude bufikelele okanye bugqithile kwimigangatho yamazwe ngamazwe, ukubonelela ngesiseko esiluqilima kwizicelo ezahlukeneyo zoshishino.

Kwizicelo ezisebenzayo, i-ASTM A106/A53/API 5L GR.Bumbhobho wentsimbi webakala B uqhuba kakuhle ngokukodwa. Kwintsimi yokuthuthwa kweoli kunye negesi yendalo, isetyenziswa ngokubanzi ekwakhiweni kweoli kunye nemibhobho yegesi ngenxa yokumelana nokugqwesa kwayo okugqwesileyo, ukumelana noxinzelelo kunye nobomi obude. Ukongezelela, olu hlobo lwentsimbi ludlala indima ebalulekileyo kwishishini lemichiza, amandla ombane, ukwakhiwa kunye nezinye iindawo, okwenza igalelo elikhulu ekuphuhliseni ishishini lanamhlanje.

Kakade ke, naziphi na izinto eziphathekayo zinemida yazo. I-ASTM A106/A53/API 5L GR.Bumbhobho wensimbi webakala B awukho ngaphandle. Kwizicelo ezisebenzayo, kufuneka sikhethe izinto ezifanelekileyo zombhobho wensimbi kunye neenkcukacha ezisekelwe kwindawo ethile yokusebenza kunye neemeko zokusetyenziswa ukuqinisekisa ukhuseleko kunye nokuzinza kweprojekthi.
Ngokubanzi, ASTM A106/A53/API 5L GR.BUmbhobho wensimbi we-steel grade B yimathiriyeli yezoshishino kunye nokusebenza okugqwesileyo kunye nesicelo esibanzi. Ngokuqonda ngokunzulu ukusebenza kwayo okusisiseko kunye nokusetyenziswa okusebenzayo, sinokudlala ngcono indima yayo ebalulekileyo kushishino lwanamhlanje kwaye sibe negalelo kuphuhliso oluzinzileyo loluntu.

Ngexesha lenkqubo yokwenziwa kwemibhobho yentsimbi, i-ASTM A106/A53/API 5L GR.Bizixhobo zentsimbi zebakala B kufuneka zilandele ulawulo olungqongqo lwenkqubo kunye nokuhlolwa komgangatho. Ukususela ekukhethweni kwezinto eziluhlaza ukuya ekuqulunqweni kweenkqubo zemveliso ukuya ekuhlolweni nasekuvavanyweni kweemveliso zokugqibela, ikhonkco ngalinye libalulekile. Kuphela ngale ndlela sinokuqinisekisa ukuba umgangatho kunye nokusebenza kwemibhobho yensimbi ihlangabezana nemigangatho elindelekileyo kwaye ihlangabezana neemfuno zabathengi.

Ngokuqhubela phambili okuqhubekayo kwenzululwazi kunye nobuchwepheshe kunye nophuhliso olukhawulezayo lweshishini, iimfuno zezixhobo zemibhobho yentsimbi ziba phezulu kwaye ziphezulu. I-ASTM A106/A53/API 5L GR.BUmbhobho wensimbi we-steel grade B, njengento eqolileyo kunye nexesha elide eqinisekisiweyo yomgangatho ophezulu, uhlala eyamkela imingeni emitsha kunye neemvavanyo. Ukuze kuhlangatyezwane nemfuno yemarike kunye nokumelana nokukhuphisana okukhulayo kokusingqongileyo, abavelisi bemibhobho yentsimbi kufuneka ngokuqhubekayo bahlaziye kwaye baphucule, baphucule umgangatho wemveliso kunye nokusebenza, banciphise iindleko zemveliso, kwaye bakhulise ukukhuphisana.

Kuphuhliso lwexesha elizayo, ASTM A106/A53/API 5L GR.BUmbhobho wensimbi we-steel grade B uya kuqhubeka nokudlala indima ebalulekileyo kwiinkalo ezahlukeneyo. Ngophuhliso olukhawulezayo lwamandla amatsha, izinto ezintsha kunye namanye amashishini, amasimi esicelo semibhobho yensimbi aya kwandiswa ngakumbi, kwaye iimfuno zezinto zombhobho zensimbi ziya kuba zihluke ngakumbi. Ngoko ke, kufuneka siqhube uphando olunzulu kunye nokuhlola ngokuqhubekayo ukuphucula ukusebenza kunye nomgangatho wemibhobho yensimbi kwaye senze igalelo elikhulu ekuphuhliseni ishishini lanamhlanje.

Ngamafutshane, ASTM A106/A53/API 5L GR.BUmbhobho wensimbi we-steel grade B, njengento ebalulekileyo yoshishino, uye waba yinxalenye ebalulekileyo yoshishino lwanamhlanje kunye nokusebenza kwayo okugqwesileyo kunye noluhlu olubanzi lwezicelo. Ngokusebenzisa uhlalutyo olunzulu kunye nophando olusebenzayo olusebenzayo, sinokuyazi kwaye siyiqonde ngcono le nto, sinike umdlalo opheleleyo kwindima yayo ebalulekileyo kumashishini anamhlanje, kunye negalelo kwinkqubela phambili kunye nophuhliso loluntu.
