ʻO nā paipu wiliwili ʻia ʻo Spiral Submerged Arc no ka ʻoihana hou

ʻO ka wehewehe pōkole:

Ma waena o ka ʻāina ākea o ka ʻoihana hou, ke ʻimi mau nei nā ʻenekinia a me nā ʻoihana i nā hopena maikaʻi loa e hoʻokō i nā pono like ʻole o ka ʻoihana a me ka halihali.Ma waena o nā ʻenehana hana paipu i loaʻa,paipu wiliwili ʻia arc submerged arc(SSAW) ua puka mai ma ke ʻano he koho hilinaʻi a maikaʻi hoʻi.Ke manaʻo nei kēia blog e hoʻomālamalama i nā pono nui a me nā pilikia e pili ana i kēia ʻenehana hana paipu hou.

Nā pōmaikaʻi o ka paipu welded arc submerged spiral:

1. Hana maikaʻi:

Hōʻike nā paipu SSAW i kahi hoʻolālā weld spiral e hiki ai ke hana pono a hoʻemi i ka manawa hana.ʻO kēia hiʻohiʻona kūʻokoʻa e lilo ia i mea koho mua no nā papahana kūkulu nui e like me ka aila a mepaipu kinoea, nā ʻōnaehana hoʻoili wai, a me nā paepae ʻeli kai.ʻO ke kaʻina hana hoʻomau hoʻomau e hōʻoia i kahi kiʻekiʻe o ka pono o ka hoʻolālā, hoʻonui i ka lōʻihi a me ke ola lawelawe o ka paipu.

2. Ka ikaika a me ka maʻalahi:

ʻO ka hoʻolālā spiral o ka paipu SSAW e hoʻonui i kona ikaika, e ʻae iā ia e pale i nā kaomi o waho a me loko.Hiki i kēia mau paipu ke kū i nā kūlana o ka lewa nui, i kūpono no nā noi ma luna a ma lalo.Eia kekahi, ʻo ka maʻalahi o nā paipu SSAW e hiki ai iā lākou ke maʻalahi a hoʻokomo ʻia i nā ʻano ʻāina like ʻole, me ka ʻāina ʻōpuʻu a me nā lepo paʻa ʻole.

3. Hoʻoholo kūʻai maikaʻi:

ʻO nā kaʻina hana kuʻihao mau e hoʻonui i ka huahana ʻoiai e hōʻemi nui ana i nā hemahema wili a me nā kumukūʻai.Hoʻohui hou, hāʻawi nā spiral submerged arc welded pipes i ka ikaika a me ka lōʻihi, e hōʻemi ana i ka mālama ʻana a me ka hoʻoponopono ʻana i nā kumukūʻai i ko lākou ola ʻana, e hoʻolilo iā lākou i koho waiwai no ka ʻoihana.

 

Helical Submerged Arc Welding

ʻO nā pilikia i kū ʻia e nā paipu i hoʻoheheʻe ʻia arc submerged:

1. Mana maikaʻi:

Ma muli o nā kaʻina hana wiliwili paʻakikī e pili ana i ka hana ʻana i nā paipu hoʻoheheʻe arc submerged arc, paʻakikī ka hōʻoia ʻana i ka maikaʻi.Inā ʻaʻole mālama pono ʻia nā ʻāpana kuʻi, hiki mai nā hemahema e like me ka undercuts, pores, a me ka nele o ka hui ʻana.No ka lanakila ʻana i kēia paʻakikī, he mea koʻikoʻi nā hana hoʻomalu maikaʻi a me nā ʻōnaehana nānā holomua i ka wā o ke kaʻina hana.

2. Paipu anawaena palena palena:

ʻOiai he mea kūpono nā paipu wiliwili puʻupuʻu i loko o ka spiral no nā noi anawaena nui, ʻaʻole kūpono paha ia no nā ʻoihana e koi ana i nā nui paipu liʻiliʻi.ʻOi aku ka maikaʻi o ke kaʻina hana no nā paipu anawaena nui aʻe, ka hopena o ka loaʻa ʻana o nā mea liʻiliʻi no nā papahana liʻiliʻi e like me ka paipu hale a me nā hoʻohana ʻoihana liʻiliʻi.No ia mau koi, pono e noʻonoʻo ʻia nā ʻenehana hana paipu ʻē aʻe.

3. Ka uhi ili:

ʻO kekahi paʻakikī e kū nei i ka ʻoihana paipu SSAW ʻo ka hōʻoia ʻana i nā uhi ʻili kūpono a paʻa e pale aku i ka ʻino a me ka ʻaʻahu.Pono ka hoʻohana ʻana i ka uhi ʻana ma luna o ka spiral surfaces i nā mea hana kiʻekiʻe a me ka ʻike e hōʻoia i ka uhi ʻana a me ka pili.He mea koʻikoʻi ka uhi ʻana i ka ʻili kūpono no ka hoʻolōʻihi ʻana i ke ola o ka paipu welded arc submerged arc, ʻoi aku ma nā wahi ʻino.

I ka hopena:

Ua hōʻike ʻia nā paipu wili ʻia ʻo Spiral submerged arc he ʻenehana maikaʻi loa i ka ʻoihana hou, e hāʻawi ana i ka pono, ikaika a me ka uku-pono.ʻO kāna wili weld spiral kū hoʻokahi e hiki ai ke hana maikaʻi a hoʻonui i ka lōʻihi, kūpono ia no nā hana kūkulu nui.Eia nō naʻe, no ka holomua ʻana a me ka hoʻohana nui ʻana i kēia ʻenehana hana, pono e hoʻoponopono ʻia nā pilikia e like me ka mālama ʻana i ka maikaʻi, ka palena palena palena, a me nā uhi uhi.Ma ka lanakila ʻana i kēia mau paʻakikī ma o ka holomua ʻenehana a me ka hui pū ʻana o ka ʻoihana, ua loaʻa i ka spiral submerged arc welded pipe ka wā e hiki mai ana i ka hoʻololi ʻana a me ka mālama ʻana i nā ʻoihana koʻikoʻi a puni ka honua.
