Kana purojekiti "ine hutsanana asi isina hutachiona," yakajairwa hutsanana hutsanana hunowanzo kukwana. Kana "kubvumidzwa-kuchifambiswa" (kuchena kwepamusoro kana mutauro wemishonga), chirevo chacho chinowanzo simbisa chemistry, kushivirira, uye bvunzo zvinotarisirwa.

Kana corrosion vimbiso iri chikamu chekugamuchirwa, A270 inobvumira kuwedzera corrosion zvinodiwa:

• Intergranular corrosion testyeAustenitic Stainless (A262 tsika inoratidzwa)
• Duplex phase-inoenderana cheki yemagiredhi maviri (A923 nzira inotaridzwa)

Procurement tip: kana purojekiti ichidaidza corrosion bvunzo kana passivation, usafunge kuti "yakajairwa." Iise muPO-wobva wada report iri mugwaro pack.

Sanitary tubing inowanzorambwa nekuda kwepepa uye kubata kukuvadzwa-kwete kwechemistry.

Kutenga matipi: yeakakwenenzverwa / EP tubing, wedzera:

• End caps
