"Sanitaire" ezali étiquette te-ezali résultat ya kondima.ASTM A270 tube sanitaireelakisaka tango projet moko etali bopeto, bosilisi ya likolo oyo ekoki kozongelama, mpe mikanda ya botangi-ya prêt. Basombi bakoki kolukalukaa270 tuyaux sanitaires ya acier inoxydabletoa270 tube sanitaire en acier inoxydable, kasi logique ya kosomba ezali ndenge moko: lakisa mwa makambo oyo epekisaka mpenza kosala lisusu, koboya, mpe "mpo na nini pince oyo ekokani te?" ba moments ya ba moments.

Awa na nse ezali lolenge ya kosalela, oyo ezali-ya mobulumobulu te mpo na kolakisaa270 ba tubes sanitairesyango wana ekomi fabrication-prêt mpe acceptation-amical.

Esika ASTM A270 Ezali Kokokana

ASTM A270 ekomami mpo na ba tubes inoxydables sanitaires (hygiéniques) oyo esalelamaka na miliki/bilei, na bio-traitement, mpe na ba services misusu oyo esengaka finition spéciale ya surface mpe ba tolérances contrôlées. Ezali kozipasans soudure, esalemi na soudure, mpemalili makasi basalaki soudureba tubes, y compris ba routes soudées ERW/EFW.

Soki projet ezali "hygiénique mais stérile te," mbala mingi spec sanitaire standard ekoki. Soki ezali "validation-driven" (pureté ya likolo to monoko ya pharma), spec typiquement e serrer na chimie, tolerances, mpe ba expectations ya test.

Biloko ya komeka mpe masengami ya kobakisa

A270 ezo référencer ba vérifications mécaniques na qualité lokolaflattening-ba tests oyo etali yangompe moko to mosusutest hydrostatique to test électrique oyo ebebisaka tena kotalela ndenge oyo motindo ekomami.

Tango assurance ya corrosion ezali eteni ya acceptation, A270 epesi nzela na ba exigences supplémentaires ya corrosion:

Test ya corrosion intergranulairempo na inoxydable austénitique (A262 pratique référence) .
Ba vérifications oyo etali phase duplex- pona ba grades duplex (méthode A923 référencé)

Conseil ya achat : soki projet ebengi ba tests ya corrosion to passivation, ko assumer te que ezali "standard." Tia yango na PO-na sima senga rapport na kati ya pack ya mikanda.

Kotya bilembo, kotya biloko na kati ya biloko, mpe Kozwa

Mbala mingi baboyaka ba tubes sanitaires mpo na mikanda mpe kosimba mbeba-te mpo na chimie.

Botiami bilembo ya A270 ekoki kopesama mitindo ya kozala na nzela ya bokeli (SML/WLD/HCW) mpe masengi ya botiami bilembo ekangami na ba références ya momesano ya botiami bilembo na ndenge ya générale. Mbala mingi, biloko oyo batyaka na kati ya emballage ezalaka na biloko oyo batyaka na kati ya biloko mpe ebatelami; emballage ya boîte ekoki kosenga mpo na biloko ya likolo-finish.

Conseil ya achat: pona ba tubes poli/EP, bakisa:

Ba bouchons ya suka
Méthode ya emballage ya propre (po na ko réduire risque ya contamination/gratch) .
Liste ya traçabilité ya pete "eteni-na-chaleur/lot" soki projet ezali audit-kilo
