hot-dip lagalvanized carbon steel pipe q235 impahla
Imfuneko yomgudu wensimbi oqinile oqinile
1).Ingaphakathi nangaphandle enamathela surface
Indawo yangaphakathi akumele ingabi nasici.Ingaphakathi nangaphandle elidiphu elishisayo ukuze linikeze ukuvikelwa kongqimba lwe-galvanic corrosion.Nakuba phezulu camera nge ungqimba ehambisanayo eziphilayo ukuvikela nokugqwala okumhlophe.Indawo engaphakathi imbozwe ngokulinganayo ukuze kube lula ukudonsa ucingo, ngisho nangamajika amaningi angu-90°.
2).Ukushisela
Ukushiselwa kwawo wonke ama-seam kufanele kuqhubeke futhi kwenziwe ngendlela efana nomsebenzi.
3).Ukuhlanza
I-conduit kufanele ihlanzwe ngokwanele ngaphambi kokusetshenziswa kwengubo yokuzivikela.Inqubo yokuhlanza izoshiya izindawo zangaphandle nezangaphakathi ze-conduit esimweni sokuthi ukumbozwa kokuvikela kuzoba bushelelezi futhi kubambelele ngokuqinile.
4).Ukuvikela ukumelana nokugqwala
a.Indawo yangaphandle
Ingaphandle kufanele inamethwe kahle nangokulinganayo nge-zinc eyinsimbi noma ivikelwe ngenye indlela yokumelana nokugqwala (ACRC).
b.Indawo yangaphakathi
Indawo yangaphakathi kufanele ivikelwe nge-zinc, noma i-organic coating.I-coating yangaphakathi kufanele ibe nobuso obushelelezi obuqhubekayo.Ukwehluka kwezikhathi ezithile ngenxa yokugeleza okungalingani kokunamathela kuzokwamukeleka.
5).Ukwelashwa kwendawo
Noma yikuphi ukwelashwa okungaphezulu okungeqi ku-0.00015 intshi (0.0038 mm) okusetshenziswa njengejazi langaphezulu noma okuguquguqukayo akudingekile ukuze kuhlangatshezwane nezimfuneko ze-ACRC noma i-organic coating.
