Kiekie Kiekie Coating Steel Paipu
Kiekie Kiekie Coating Steel Paipu
(1) Hiki ke hoʻokaʻawale ʻia ke kaʻina hana o ka paipu kila seamless i kekahi mau ʻano kumu: ʻōwili wela (extrusion), ʻōwili ʻia (ka huki) a me ka paipu kila hoʻonui wela.
(2) E like me ke kaʻina hana, hiki ke hoʻokaʻawale ʻia ka paipu wili i ka paipu kila wili pololei, ka paipu kila wiliwili, ka pā coil butt welded steel pipe a me ka welded pipe thermal expansion steel pipe.
E like me ke ano, kila paipu hiki ke maheleia i: poepoe paipu, huinahalike paipu, rectangular paipu, octagonal, hexagonal, D-ʻano, pentagonal a me ka kūikawā-mea kila paipu, paʻakikī pauku kila paipu, pālua concave kila paipu, elima petal. paipu kila quincunx, paipu kila conical, paipu kila corrugated, paipu kila hua melon, paipu kila convex pālua, etc.
Hiki ke maheleia ka paipu kila i: paipu kila no ka paipu, paipu kila no na mea wela, ka paipu kila no ka oihana mechanical, ka paipu kila no ka aila a me ka wili honua, ka ipu hao, ka paipu kila no ka oihana kemika, ka paipu kila no ka hana kūikawā, etc. ʻO ka hoʻokaʻawale ʻana o ka pā i loko: ka uhi ʻana i ka wai epoxy ipn8710 anti-corrosion a me ka hui ʻana i hoʻopaʻa ʻia i ka pauka epoxy anti-corrosion.
Ka hoʻokaʻawale ʻana o ka pā o waho e kūʻē i ka corrosion: pelu ʻana i ka 2PE / 3PE anti-corrosion, hoʻokahi-layer PE anti-corrosion a me ka epoxy coal asphalt anti-corrosion.Kūleʻa kūʻē i ka corrosion: FBE epoxy pauka anti-corrosion e hoʻokō me SY / t0315-2005 kikoʻī ʻenehana no ka papa hoʻokahi fusion i hoʻopaʻa ʻia epoxy pauka i waho o ka paipu kila, 2PE / 3PE anti-corrosion e hoʻokō me GB / t23257-2009 maʻamau no ka ʻenehana. polyethylene uhi waho o kanu kila pipeline, anti-corrosion ili rust removal maʻamau: one pahū ma luna o waho ili o ke kila paipu e hiki SA2 1 / 2 e like me na koi o GB / t8923-2008, a me ka hohonu o ka heleuma palaoa ma ka ili o ka paipu kila e 40-100 μm.
ʻO nā mea kumu o nā paipu kila anti-corrosion e pili ana i nā paipu spiral, nā paipu seam pololei, nā paipu seamless, etc. , hoʻomaʻemaʻe wai, kumu wai, alahaka, hale kila, hoʻoili wai kai a me ka hoʻopaʻa ʻana.
Ma kahi o ka hoʻomaikaʻi ʻana i ke ola lawelawe o ka paipu kila ma o ka anti-corrosion, ʻike ʻia nō hoʻi ia ma nā ʻano aʻe:
1. Hoʻohui i ka ikaika mechanical o ka paipu kila me ka pale ʻana o ka palaka;
2. ʻOi aku ka nui o ka pā o waho ma mua o 2.5mm, kūpaʻa i ka ʻōpala a me ka hui ʻana;
3. He liʻiliʻi ka heluna friction o ka pā i loko, 0.0081-0.091, e hōʻemi ana i ka hoʻohana ʻana i ka ikehu;
4. Hoʻokō ka pā i loko i nā kūlana olakino olakino;
5. He laumania ka paia o loko a ʻaʻole maʻalahi ka unahi, me ka hana hoʻomaʻemaʻe ponoʻī.
