paipu hao-hao-hao02

Paipu kila galvanizedhe paipu kila i hana ʻia ma ka uhi ʻana i kahi papa zinc ma ka ʻili o ka paipu kila maʻamau (paipu kila carbon). Loaʻa i ka Zinc nā waiwai kemika ikaika a hiki ke hana i kahi kiʻiʻoniʻoni oxide nui, a laila e hoʻokaʻawale i ka oxygen a me ka makū a pale i ka paipu kila mai ka pala.GI paipu kilahe paipu metala me ka uhi zinc ma ka ʻili o ka paipu kila maʻamau e pale ai i ka ʻino. Hoʻokaʻawale ʻia ia i ka galvanizing hot-dip a me ka electro-galvanizing. Luʻu welapaipu kila galvanizedua hoʻokomo ʻia i loko o ka wai zinc hoʻoheheʻe ʻia (e pili ana i 450 ° C) e hana i kahi papa zinc ʻoi aku ka mānoanoa (50-150μm), nona ke kūpaʻa corrosion ikaika a kūpono i nā wahi o waho a i ʻole ka humid; Hoʻohana ka paipu kila electro-galvanized i ke kaʻina electrolysis, ʻoi aku ka lahilahi o ka papa zinc (5-30μm), ʻoi aku ka haʻahaʻa o ke kumukūʻai, a hoʻohana nui ʻia i loko o ka hale.

Nā kikoʻī o ka paipu hao hao

Ka nui a me ke anawaena

1. Nominal diameter (DN): ʻO ka laulā maʻamau ʻo DN15 ~ DN600 (ie 1/2 iniha ~ 24 iniha).

2. Outer anawaena (OD):

(1) .Small diameter pipe: e like me DN15 (21.3mm), DN20 (26.9mm).

(2) .Medium a me ka nui anawaena paipu: e like me DN100 (114.3mm), DN200 (219.1mm).

3.British kiko'ī: Kekahi mau i hōʻike 'ia i loko o 'īniha, e like me 1/2", 3/4", 1", etc.

Ka mānoanoa o ka pā a me ka helu kaomi

1. ʻO ka mānoanoa pā maʻamau (SCH40): kūpono no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa (e like me nā paipu wai, nā paipu kinoea).

2. Thickened pā mānoanoa (SCH80): kiʻekiʻe kiʻekiʻe puʻe kū'ē, hoʻohana no ka structural kākoʻo 'ole kiʻekiʻe-press scenario.

3.National maʻamau pā mānoanoa: E like me ka mea i hoakaka ia ma GB / T 3091, ka mānoanoa o ka paia o DN20 galvanized paipu kila he 2.8mm (maʻamau papa).

Ka lōʻihi

1. Ka lōʻihi maʻamau: maʻamau 6 mika / ʻāpana, 3m, 9m a i ʻole 12m hiki ke hoʻopili ʻia.

2.Paʻa ka lōʻihi: ʻoki e like me nā koi o ka papahana, ʻae ʻia ka hewa ± 10mm.

Nā mea a me nā kūlana

1.Base paipu mea:Q235 kalapona kila, Q345 haʻahaʻa kila kila, etc.

2.Galvanized papa mānoanoa:

(1) .Hot-dip galvanizing: ≥65μm (GB / T 3091).

(2) .Electrogalvanizing: 5 ~ 30μm (nāwaliwali rust kū'ē).

3. Nā kūlana hoʻokō:

(1) Kina: GB / T 3091 (welded galvanized pipe), GB / T 13793 (seamless galvanized pipe).

(2) .International: ASTM A53 (American standard), EN 10240 (European standard).

Kaʻina wiliwili paipu hao hao

Ka nui a me ke anawaena

ʻO ke ala wiliwili: Hoʻohana pinepine ʻia nā ʻano hoʻoheheʻe ʻana me ka manual arc welding, ka hoʻoheheʻe ʻana i ke kinoea, ka hoʻoheheʻe ʻana i ke kinoea CO2, a me nā mea ʻē aʻe.

Hoʻomākaukau welding: Ma mua o ke kuʻi ʻana, pono e hoʻoneʻe ʻia nā mea haumia o ka ʻili e like me ka pena, ka ʻōpala a me ka lepo ma ka wahi wili e hōʻoia i ka maikaʻi o ka weld.

Kaʻina hana welding: I ka wā welding, pono e hoʻomalu ʻia ke ʻano o kēia manawa, ka uila a me ka wikiwiki o ka welding e pale aku i nā pilikia e like me ka undercut a me ke komo ʻole ʻana. Ma hope o ke kuʻi ʻana, pono e hoʻokō ʻia ka hoʻoluʻu a me ka ʻokiʻoki e pale i ka deformation a me nā māwae.

Ka mana maikaʻi: I ka wā welding, pono e uku ʻia i ka palahalaha a me ka maʻalahi o ka weld e pale aku i nā hemahema e like me nā pores a me nā slag inclusions. Inā loaʻa nā pilikia maikaʻi o ka welding, pono e mālama ʻia a hoʻoponopono ʻia i ka manawa kūpono.

Hale Ame Hana Hana

1. Ke kūkulu ʻia ʻana o ka scaffolding

E hoʻohana: kākoʻo manawaleʻa no ke kūkulu ʻana, kahua hana pā o waho.

Nā kikoʻī: DN40 ~ DN150, mānoanoa pā ≥3.0mm (SCH40).

Pōmaikaʻi: ikaika kiʻekiʻe, maʻalahi ka wehe ʻana a me ka hui ʻana, ʻoi aku ka pale ʻana i ka ʻōpala ma mua o nā paipu kila maʻamau.

2.Steel hoʻolālā 'āpana kōkua
E hoʻohana: nā alapiʻi lima, nā pā hale, nā kolamu pā.

Nā hiʻohiʻona: Hiki ke hoʻohana ʻia ka pale galvanizing ma waho no ka manawa lōʻihi, e hōʻemi ana i nā kumukūʻai mālama.
