Paipu pōʻai pōʻai wiliwili ʻia

Hoʻokaʻawale ʻia nā paipu kila Galvanized i ʻelua ʻano: hot-dip galvanizing a me electro-galvanizing.He mānoanoa ka papa galvanizing wela, he haʻahaʻa ke kumukūʻai o ka electro-galvanizing, a ʻaʻole maʻalahi ka ʻili.ʻO ka paipu hoʻoheheʻe ʻia o ka oxygen: hoʻohana ʻia no ka hana kila o ka puhi ʻana i ka oxygen, nā paipu kila wili liʻiliʻi liʻiliʻi, me nā kikoʻī ʻewalu mai ka 3/8 a 2 iniha.E hoʻohana i ka 8, 10, 15, 20 a i ʻole Ua hana ʻia ʻo 195-Q235 kila kila, i mea e pale ai i ka corrosion, pono ia e hoʻokō i ka mālama aluminizing.

Hot-dip galvanized welded pipe ka mea e hoʻoheheʻe ai i ka metala i hoʻoheheʻe ʻia me ka matrix hao e hana ai i kahi ʻāpana, i hui ʻia ka matrix a me ka uhi.ʻO ka galvanizing wela ka hoʻomaʻamaʻa mua ʻana i ka paipu kila.I mea e wehe ai i ka hao oxide ma luna o ka ʻili o ka paipu kila, ma hope o ka pickling, e hoʻomaʻemaʻe ʻia i loko o kahi pahu me ka ammonium chloride a i ʻole ka zinc chloride aqueous solution a i ʻole ka hopena aqueous hui ʻia o ka ammonium chloride a me ka zinc chloride, a laila hoʻouna ʻia i In the pahu hoʻoheheʻe wela.Loaʻa i ka Hot-dip galvanizing nā mea maikaʻi o ka uhi ʻaʻahu, ka hoʻopili ikaika a me ke ola lawelawe lōʻihi.

Cold galvanizing mea electro-galvanizing, a me ka nui o ka galvanizing mea uuku loa, wale 10-50g/m2, a me kona corrosion kū'ē i oi aku ka hewa ma mua o ka wela-luu galvanized paipu.
