Kulwandle olukhulu lweshishini lensimbi, i-20 ye-alloy ipayipi yensimbi iye yaba yindima ebalulekileyo kwaye ibalulekileyo kunye neempawu zayo ezizodwa kunye neendawo ezibanzi zokusebenzisa.

Okokuqala, inkcazo yenkcazo yepayipi yensimbi ye-alloy ye-20
Njengoko igama libonisa, i-20 ye-alloy iron pipe yipayipi yensimbi eyenziwe nge-No. Iimpawu zayo zihlukeneyo, kwaye imigangatho eyahlukeneyo ifumaneka ukusuka kwi-diameter yangaphandle, kunye nobukhulu bodonga ukuya kubude. Iimpawu eziqhelekileyo zangaphandle zedayamitha ziyi-Φ15-630mm, ububanzi bodonga ukusuka kwi-1.5mm ukuya kumashumi eemilimitha, kwaye ubude ubukhulu becala busisigxina ubude okanye ubude obuninzi. Ukwahlukana kwezi nkcukacha kwenza ukuba i-pipe yensimbi ye-alloy ye-20 ihlangabezane neemfuno zemimandla eyahlukeneyo kunye neemeko.

Okwesibini, iimpawu zezinto eziphathekayo kunye neenzuzo zokusebenza zeNombolo ye-20 yensimbi yensimbi yombhobho
Isizathu sokuba i-pipe ye-alloy ye-20 ye-alloy ithandwa kakhulu ayinakuhlukaniswa kwiimpawu zayo zezinto eziphathekayo kunye neenzuzo zokusebenza. Okokuqala, i-20 yensimbi, njengento esisiseko, inamandla afanelekileyo kunye nokuqina, okwenza umbhobho wensimbi ye-alloy usebenze kakuhle xa uphantsi kwamandla angaphandle njengoxinzelelo kunye neempembelelo. Okwesibini, ngokongeza izinto ze-alloy, ukuxhathisa kwe-corrosion kunye nokuchasana nobushushu obuphezulu bemibhobho yensimbi kuye kwaphuculwa kakhulu, okwenza kube lula kwiindawo zokusebenza ezifuna kakhulu. Ukongeza, imibhobho yentsimbi ye-alloy engama-20 nayo ine-weldability elungileyo kunye ne-processability, eququzelela ukufakela nokugcinwa kamva.

Okwesithathu, imimandla yesicelo kunye nohlalutyo lwemeko yeNombolo ye-20 yeepayipi zensimbi ye-alloy
Imibhobho yentsimbi ye-alloy engama-20 isetyenziswa ngokubanzi kwiinkalo ezininzi ezifana ne-petroleum, ishishini lemichiza, amandla ombane kunye noomatshini. Kwishishini le-petroleum, lihlala lisetyenziswa njengezinto eziphambili ezifana nemibhobho yeoli kunye ne-oyile ye-oyile casings, kwaye iphantsi koxinzelelo oluphezulu kunye novavanyo oluphezulu lobushushu; kwishishini lemichiza, ukuxhathisa ukubola kwenza kube lukhetho olufanelekileyo lwezixhobo zekhemikhali kunye nemibhobho; kwishishini lamandla, No. 20 ingxubevange imibhobho yentsimbi zisetyenziselwa ukuvelisa izixhobo eziphambili ezifana imibhobho kwibhoyila kunye nemibhobho umphunga ukuqinisekisa ukusebenza oluzinzileyo inkqubo yamandla.

Okwesine, iingcebiso zokuthenga kunye nokufakwa kweNombolo ye-20 ye-alloy steel pipes
Xa kuthengwa imibhobho yensimbi ye-20 ye-alloy, abathengi kufuneka bahlawule ingqalelo kwiincwadi zabo zokuqinisekisa umgangatho kunye neelogos ukuqinisekisa ukuba iipayipi zetsimbi ezithengiweyo zihlangabezana nemigangatho efanelekileyo kunye neenkcukacha. Kwangaxeshanye, iinkcukacha ezifanelekileyo kunye nobude kufuneka zikhethwe ngokweemfuno zangempela ukuphepha inkcitho kunye nenkcitho yeendleko ezingeyomfuneko. Ngethuba lenkqubo yokufakela, iinkqubo ezifanelekileyo zokusebenza kufuneka zilandelwe ukuze kuqinisekiswe ukuba umbhobho wensimbi uqiniswe kwaye uqiniswe ngokuqinileyo ukukhusela ukuvuza okanye iingozi zokhuseleko ezibangelwa ukufakwa okungafanelekanga. Ukongezelela, ukusetyenziswa kwexesha elide lemibhobho yensimbi ye-alloy ye-20, ukuhlolwa rhoqo kunye nokugcinwa kufuneka kuqhutywe ngokukhawuleza ukufumanisa nokujongana nobungozi obunokhuseleko. Ngethuba lokugcinwa kwenkqubo, amanyathelo afana nokusebenzisa i-anti-corrosion paint kunye nokutshintsha iindawo ezonakalisiweyo zingamkelwa ukwandisa ubomi benkonzo yombhobho wensimbi.

Okwesihlanu, uphuhliso lwexesha elizayo kunye nembonakalo yeNombolo ye-20 ye-alloy steel pipes
Ngenkqubela phambili eqhubekayo yesayensi kunye nobuchwepheshe kunye nokwandiswa okuqhubekayo kwendawo yoshishino, i-20 ye-alloy steel pipes iya kujongana namathemba okusebenza ngokubanzi kunye neemfuno eziphezulu. Kwixesha elizayo, ishishini lombhobho wensimbi liya kuqhubeka nokuphuhlisa izinto ezintsha ze-alloy kunye nokuphucula izibonakaliso zokusebenza zemibhobho yentsimbi ukuhlangabezana neemfuno zeendawo zokusebenza ezingqongqo. Kwangaxeshanye, ngokuphuculwa kokuqatshelwa kokusingqongileyo, iinkqubo zokuvelisa uhlaza kunye nokusingqongileyo kunye nezinto eziphathekayo ziya kuba lukhokelo olubalulekileyo kuphuhliso lweshishini.

Ngamafutshane, iipayipi zensimbi ze-20 ze-alloy ziye zaba yiperile ekhanyayo kwishishini lensimbi kunye neempawu zabo ezizodwa kunye neendawo ezibanzi zokusebenzisa. Ngokuziqonda nzulu iimpawu zayo ezichaziweyo, izibonelelo zokusebenza, kunye neemeko zesicelo, sinokuyiqonda ngcono le mveliso kwaye sandise ixabiso layo kwizicelo ezisebenzayo. Kuphuhliso lwexesha elizayo, i-20 ye-alloy iron pipe iya kuqhubeka idlala indima ebalulekileyo kwaye ibe negalelo kwinkqubela phambili kwiinkalo ezahlukeneyo.
