ASTM A270 Sanitary Tubing RFQ Umhlahlandlela

ASTM A270 stainless steel tube size range

I-"Sanitary" ayiyona ilebula-iwumphumela wokwamukelwa.I-ASTM A270 ishubhu ye-sanitaryibonakala uma iphrojekthi ikhathalela ukuhlanzeka, ukuphela kwendawo okuphindaphindwayo, kanye nokuhlolwa{0}} kwamadokhumenti alungile. Abathengi bangase baseshea270 amapayipi ensimbi engagqwalinomaa270 insimbi engagqwali sanitary tubing, kodwa ingqondo yokuthenga iyafana: cacisa imininingwane embalwa empeleni evimbela ukusebenza kabusha, ukwenqatshwa, kanye nokuthi "kungani lesi siqiniseko singalingani?" izikhathi.

Ngezansi kunendlela esebenzayo,{0}}engeyona indlela ethambile yokucacisaa270 amashubhu ahlanzekilengakho-ke kufika ukwakhiwa-sekulungele futhi kwamukeleka-kunobungane.

Lapho I-ASTM A270 Ilingana

I-ASTM A270 ibhalelwe amashubhu ahlanzekile (ahlanzekile) asetshenziswa ebisi/ekudleni, ekucutshungulweni kwe-bio-, nezinye izinsiza ezidinga ukuqedwa okuphezulu okukhethekile nokubekezelelana okulawulwayo. Ihlanganisaengenamthungo, ezishiselwe, futhikubanda kakhulu wasebenza weldedamashubhu, okuhlanganisa imizila eshiselwe i-ERW/EFW.

Uma iphrojekthi "ihlanzekile kodwa ingeyona inyumba," i-spec yenhlanzeko evamile ngokuvamile yanele. Uma "kuqhutshwa ukuqinisekiswa-kuqhutshwa" (ukuhlanzeka okuphezulu noma ulimi lwe-pharma), ukucaciswa kuvame ukuqina kukhemistri, ukubekezelelana, nokulindela ukuhlolwa.

Izinto Zokuhlola Nezimfuneko Ezingezekile

I-A270 ibhekisela ekuhloleni komshini nekhwalithi okufanaukuhlola{0}}okuhlobenefuthi nomaukuhlolwa kwe-hydrostatic noma ukuhlolwa kukagesi okungonakalisikuye ngokuthi i-oda libhalwa kanjani.

Uma isiqinisekiso sokugqwala siyingxenye yokwamukelwa, i-A270 ivumela izidingo zokugqwala ezengeziwe:

Ukuhlolwa kokugqwala kwe-Intergranularkwe-austenitic stainless (umkhuba we-A262 ukhonjiwe)
Isigaba se-Duplex-ukuhlolwa okuhlobene kwamabanga ayi-duplex (kubalulwe indlela ye-A923)

Ithiphu yokuthenga: uma iphrojekthi ibiza ukuhlolwa kokugqwala noma ukuphumelela, ungacabangi ukuthi "kujwayelekile." Yifake ku-PO-bese udinga umbiko kuphakethe ledokhumenti.

Ukumaka, Ukupakisha, kanye Nokwamukela

Amashubhu e-Sanitary ngokuvamile enqatshwa ngomsebenzi wamaphepha kanye nokulimala kokusingatha{0}}hhayi ngenxa yekhemistri.

Ukumakwa kwe-A270 kunga-odwa ukuthi kufake umzila wokukhiqiza (i-SML/WLD/HCW) futhi izidingo zokumaka zihlanganiswe nezithenjwa ezijwayelekile zokumaka. Ukupakishwa kuvame ukugoqwa futhi kuvikelwe; ukupakishwa okusebhokisini kungacelwa{2}}imikhiqizo yokuqeda ephezulu.

Ithiphu yokuthenga: yeshubhu epholishiwe/ye-EP, engeza:

Amakepisi wokugcina
Indlela yokupakisha ehlanzekile (ukunciphisa ukungcola/ubungozi bokuklwebheka)
Uhlu olulula "locezu{0}}lo{1}}lokushisa/ulukhulu" uma iphrojekthi icwaningwa{2}}inzima

Ibhalwa Kanjani I-RFQ/PO Esula I-QA Futhi Isiza Ukuma

Uma umgomo ukucaphuna ngokushesha kanye nezibuyekezo ezimbalwa, i-RFQ enhle yayoa270 amashubhu ahlanzekilekufanele ifundeke njengohlu lokuhlola-hhayi umdlalo wokuqagela.

Sebenzisa isakhiwo esifana nalokhu:

Okujwayelekile:I-ASTM A270
Ibanga:304/304L noma 316/316L (qinisekisa ibanga eliqondile)
Umzila:SML / WLD / HCW
Usayizi:I-OD × WT (noma i-sanitary inch OD izivumelwano)
Ubude:fixed / okungahleliwe / ngokwezifiso
Qeda:isigayo / Cha. 180 / Cha. 240 / i-electropolis
Imfuneko yokuqina:max Ra (ID/OD/kokubili) kanye nendlela yokulinganisa
Ukuhlola:ukuhlolwa kagesi kwe-hydrostatic noma i-NDE; weld NDE uma i-HCW noma iphrojekthi idinga
Ukumaka nokulandeleka:ukushisa/inqwaba, ikhodi yomzila, iphakethe ledokhumenti
Izidingo ezingeziwe:ikhwalithi ye-pharma / ukuhlolwa kokugqwala / imfuneko yokudlula

Inothi elisheshayo lokungafani kwegama elingukhiye elivamile: amanye ama-RFQ aqukethe amagama afana nalawaa270 304I-sanitary stainless tubing. Uma lokho kubonakala, kufanelekile ukuqinisekisa ukuthi inhloso iyiyo304L(izinga elivamile le-sanitary) noma iphrojekthi-ikhodi ethile yangaphakathi{1}}uhlamvu olulodwa lungashintsha lube inqwaba enqatshiwe.

Isifinyezo

Uma isicelo siyisevisi yenhlanzeko,I-ASTM A270 ishubhu ye-sanitaryinikeza uhlaka oluhlanzekile lokucacisa lokho okubaluleke kakhulu:ukuqedwa kwendawo + ukulawulwa kokuqina, ukubekezelelwa kobukhulu, ukukhetha umzila (SML/WLD/HCW), ukwelashwa kokushisa, ukumaka, nezinketho zokuhlola. Ibhalwe kahle ku-PO,a270 insimbi engagqwali sanitary tubingifika isilungele ukwenziwa nokwamukelwa{{0}ngaphandle kokumangala ekutholeni noma ngesikhathi sokuqinisekiswa.
