"Ucoceko" ayisoleyibhile{0}}sisiphumo sokwamkelwa.ASTM A270 ityhubhu zococekoibonisa xa iprojekthi ikhathalele ukucoceka, ukuphinda-phinda umphezulu wokugqiba, kunye nokuhlolwa{0}}amaxwebhu asele elungile. Abathengi banokukhangelaa270 imibhobho yentsimbi ecocekileyookanyea270 steel stainless sanitary tubing, kodwa ingqiqo yokuthenga iyafana: khankanya iinkcukacha ezimbalwa ezithintela ngokwenene ukusebenza kwakhona, ukugatywa, kwaye "kutheni le nto ingahambelani?" imizuzu.

Apha ngezantsi kukho into eyenzekayo,{0}}indlela engacacanga yokuchazaa270 iityhubhu zococekongoko ke ifike iyilwe{0}}ilungile kwaye yamkelwe-nobuhlobo.

Apho i-ASTM A270 ingena khona

I-ASTM A270 ibhalelwe iityhubhu ecocekileyo (ecocekileyo) esetyenziswa kubisi/ekutyeni, kwi-bio{1}}kusetyenzwa, kunye nezinye iinkonzo ezifuna umphezulu okhethekileyo kunye nonyamezelo olulawulwayo. Igubungelaengenamthungo, welding, kwayekubanda kakhulu wasebenza weldingiityhubhu, kuquka iindlela ezidityanisiweyo ze-ERW/EFW.

Ukuba iprojekthi "icocekile kodwa ayinyumba," umgangatho wococeko oqhelekileyo udla ngokwaneleyo. Ukuba "luqinisekiso{1}}luqhutywa" (ucoceko oluphezulu okanye ulwimi lwe-pharma), i-speckethi iqinisa kwikhemistri, ukunyamezela, kunye novavanyo olulindelekileyo.

Izinto zoVavanyo kunye neeMfuno ezongezelelweyo

A270 iimbekiselo oomatshini kunye nomgangatho iitshekhi ezifanaukucaba -uvavanyo oluyeleleneyokunye nokubauvavanyo lwe-hydrostatic okanye uvavanyo lombane olungonakalisiyokuxhomekeke kwindlela obhalwa ngayo umyalelo.

Xa isiqinisekiso somhlwa siyinxalenye yokwamkelwa, i-A270 ivumela iimfuno zomhlwa ezongezelelweyo:

Uvavanyo lwe-Intergranular Corrosioni-austenitic stainless (i-A262 ireferensiwe)
Isigaba seDuplex{0}}iitshekhi eziyeleleneyo zamabakala aphindwe kabini (indlela ye-A923 ibhekiselele)

Ingcebiso yokuthengwa kwempahla: ukuba iprojekthi ibiza iimvavanyo ze-corrosion okanye i-passivation, ungacingi ukuba "umgangatho." Yibeke kwiPO{1}}kwaye ufune ingxelo kwipakethi yoxwebhu.

Ukumakisha, ukuPakisha, kunye nokwamkela

Iityhubhu zococeko zihlala zikhatywa umsebenzi wamaphepha kunye nokuphatha umonakalo{0}hayi ngenxa yekhemistri.

Ukumakishwa kwe-A270 kunokuyalelwa ukuba kubandakanye indlela yokuvelisa (SML/WLD/HCW) kwaye iimfuno zokumakisha zibotshelelwe kwiimbekiselo zokumakisha jikelele. Ukupakishwa kuqhelekile kwaye kukhuselwe; ukupakisha okusebhokisini kunokucelwa{2}ukugqiba iimveliso eziphezulu.

Ingcebiso yokuthenga: yetyhubhu epolishiweyo/yeEP, yongeza:

Iminqwazi yokuphela
Indlela yokupakisha ecocekileyo (ukunciphisa ungcoliseko/umngcipheko wokukrwela)
Uluhlu olulula "lweqhekeza{0}}lo{1}}ubushushu/iqashiso" ukuba iprojekthi iphicothwe{2}}inzima

Indlela yokuBhala i-RFQ / PO eCoca i-QA kunye noNcedo lweNqanaba

Ukuba injongo kukucaphula ngokukhawuleza kunye nohlaziyo olumbalwa, i-RFQ elungileyo yea270 iityhubhu zococekokufuneka ifundeke njengoluhlu lokukhangela{0}}hayi umdlalo wokuthelekelela.

Sebenzisa isakhiwo esinje:

Umgangatho:I-ASTM A270
Ibakala:304/304L okanye 316/316L (qinisekisa ibakala ngqo)
Indlela:SML / WLD / HCW
Ubungakanani:I-OD × i-WT (okanye i-intshi ecocekileyo ye-OD iindibano)
Ubude:fixed / random / custom
Gqiba:isisila / Hayi{0}} / Hayi{1}} / i-electropolish
Imfuneko yoburhabaxa:max Ra (ID / OD / zombini) kunye nendlela yokulinganisa
Uvavanyo:uvavanyo lombane lwe-hydrostatic okanye i-NDE; weld NDE ukuba i-HCW okanye iprojekthi ifuna
Ukumakisha kunye nokulandeleka:ubushushu/iqashiso, ikhowudi yendlela, ipakethe yoxwebhu
Iimfuno ezongezelelweyo:umgangatho we-pharma / iimvavanyo zokubola / imfuneko yokudlula

Inqaku elikhawulezayo kwigama elingundoqo elingafaniyo: ezinye ii-RFQs ziqulathe amagama afana nalaa 270 304I sanitary stainless tubing. Ukuba oko kubonakala, kuyafaneleka ukuba kuqinisekiswe ukuba injongo injalo304L(umgangatho oqhelekileyo wococeko) okanye iprojekthi-ikhowudi ethile yangaphakathi{1}}umfanekiso omnye unokujika abe yibhetshi enye eyaliwe.

Isishwankathelo

Ukuba isicelo yinkonzo yococeko,ASTM A270 ityhubhu zococekoinika isakhelo esicocekileyo sokuchaza okona kubaluleke kakhulu:ukugqitywa komphezulu + ukulawula uburhabaxa, ukunyamezelwa komgangatho, ukhetho lwendlela (SML/WLD/HCW), unyango lobushushu, ukumakisha, kunye nokhetho lokuvavanya. Ibhalwe ngokuchanekileyo kwiPO,a270 steel stainless sanitary tubingifika ilungele ukwenziwa kunye nokwamkelwa{0}ngaphandle kokumangaliswa kukufumana okanye ngexesha lokuqinisekiswa.
