ASTM A270 Obuyonjo Tubing RFQ Guide

ASTM A270 stainless steel tube size range

"Sanitary" si label-kiva mu kukkiriza.ASTM A270 ttanka y’obuyonjoeraga nga pulojekiti efaayo ku buyonjo, okumaliriza kungulu okuddibwamu, n'ebiwandiiko ebyetegefu okwekebejja-. Abaguzi bayinza okunoonyaa270 payipu ez’ekyuma ekitali kizimbulukuse ez’obuyonjoobaa270 ekyuma ekitali kizimbulukuse eky’obuyonjo, naye ensonga y'okugula y'emu: lambika ebikwata ku bintu ebitonotono ebiziyiza mu butuufu okuddamu okukola, okugaana, ne "lwaki ekikwaso kino tekikwatagana?" ebiseera ebiseera.

Wansi waliwo engeri ey'omugaso, etali -fluffy ey'okulambikaa270 obuyonjo mu ttankakale kituuka fabrication-nga kyetegefu era okukkirizibwa-mukwano.

ASTM A270 gy’etuukira

ASTM A270 ewandiikiddwa ku buyonjo (obuyonjo) stainless tubing ezikozesebwa mu mata/emmere, bio-processing, n'empeereza endala ezeetaaga okumaliriza okw'enjawulo kungulu n'okugumiikiriza okufugibwa. Kibikkaseamless, welded, neennyonyogovu ennyo yakola weldedtubing, omuli n’amakubo aga ERW/EFW aga welded.

Singa pulojekiti eba "buyonjo naye nga si buwuka," standard sanitary spec etera okumala. Bwe kiba "okukakasa-okuvugibwa" (obulongoofu obw'amaanyi oba olulimi lwa pharma), spec etera okunyweza ku kemiko, okugumiikiriza, n'okusuubira okugezesebwa.

Ebintu Ebigezesebwa n’Ebyetaagisa eby’Okugatta

A270 ejuliza okukebera ebyuma n’omutindo ngaflattening-ebigezo ebikwataganaera obaokugezesa amazzi oba okugezesa amasannyalaze agatali ga kusaanyaawookusinziira ku ngeri ekiragiro gye kiwandiikiddwamu.

Bwe kiba nti okukakasa okukulukuta kitundu ku kukkiriza, A270 ekkiriza ebyetaago by’okukulukuta eby’okugatta:

Okugezesa okukulukuta wakati w’obutundutunduku austenitic stainless (enkola ya A262 ejuliziddwa) .
Duplex phase-related checks for duplex grades (enkola ya A923 ejuliziddwa)

Amagezi ku kugula: singa pulojekiti eyita okugezesa okukulukuta oba pasivation, tokitwala nti "standard." Kiteeke mu PO-olwo weetaaga lipoota mu pack y'ebiwandiiko.

Okussaako obubonero, Okupakinga, n’Okufuna

Sanitary tubing etera okugaanibwa olw’okukola empapula n’okukwata ebyonoonese-si lwa kemiko.

Okussaako obubonero bwa A270 kuyinza okulagirwa okubeeramu ekkubo ly’okukola (SML/WLD/HCW) era ebyetaago by’okussaako obubonero bisibiddwa ku bijuliziddwa ku nkola y’okussaako obubonero okwa bulijjo. Ebipakiddwa bitera okubeera nga bikuŋŋaanyiziddwa era nga bikuumibwa; okupakinga mu bbokisi kuyinza okusabibwa ku bintu ebimaliriziddwa ebisingako-.

Okubumbako

Singa okusaba kuba kwa buyonjo, .ASTM A270 ttanka y’obuyonjoawa enkola ennyonjo okulaga ekisinga obukulu:okumaliriza kungulu + okufuga obukaluba, okugumiikiriza ebipimo, okulonda ekkubo (SML/WLD/HCW), okulongoosa ebbugumu, okussaako obubonero, n’engeri y’okugezesa. Ewandiikiddwa bulungi mu PO, .a270 ekyuma ekitali kizimbulukuse eky’obuyonjoetuuka nga yeetegese okuyiiya n'okukkirizibwa-nga tewali kyewuunyisa ku kufuna oba mu kiseera ky'okukakasa.
