Ka moolelo o ka rebar coupler

I ka ʻoihana kūkulu hale, ʻaʻole hiki i nā ʻano hoʻohui kuʻuna kuʻuna e like me nā ʻūhā a me nā pilina welding ke hoʻomāʻona i ka hoʻomohala wikiwiki ʻana o ka ʻoihana kūkulu e pili ana i ka maikaʻi o ka pilina, ka pono, a me ka hana.ʻO ka hoʻomau mau ʻana o ka ʻenehana conical thread coupler ua alakaʻi i ka hana hou i ka ʻoihana holoʻokoʻa a me ka holomua mau ʻana i ka ʻenehana.No laila, ka pahu kilaʻenehana piliua lanakila loa ia ma kekahi ano, a he mau ano ponoi kona i hiki ai ke hoololi i ka oihana ulu mau a me na ano pilikanaka.ʻAʻole hiki ke hoʻohana ʻia ke ʻano o ka hui pū ʻana no ka hoʻopili ʻana i nā kaola kila nui, a he nui nā hemahema o ka welding (e like me nā mea kila paʻa ʻole, maikaʻi ʻole ka weldability, a me nā mea ʻē aʻe. ; nā hopena ea a me ke aniau e like me ka makani a me ka ua; nā hoʻolālā kūkulu ʻana no nā kahua me nā koi pale ahi kiʻekiʻe; ka maikaʻi a me ka wikiwiki o ka hoʻopili ʻana i ka pae ʻāʻī.)

ʻAʻole hiki ke hōʻoia i ka maikaʻi o ka welding.Hiki i ka pilina mechanical o nā pahu kila ke pale aku i nā pilikia i luna a hōʻike i nā pono kūpono.I ka hopena o nā makahiki 1980, ma o ka hoʻokomo ʻana i nā ʻenehana pili mechanical holomua ʻē aʻe, i hui pū ʻia me ka hoʻoikaika mau ʻana o nā loea kūpono o kekahi mau keʻena noiʻi ʻepekema ma Kina, ua ulu wikiwiki ka ʻenehana pili mechanical i hoʻoikaika ʻia.Ua loaʻa i ka pilina mechanical nā ʻano hana like ʻole o ka hoʻomohala ʻana e like me ka hoʻokuʻu ʻana i ka lima, ka taper threading, upsetting thread straight up to the current rolling straight thread, a ua lilo ka ʻenehana i mea makua a paʻa, a ua hoʻemi mau ʻia ke kumukūʻai.

I loko naʻe o kēia, ʻo ka ʻenehana hoʻopili kaula liʻiliʻi o Kinaaia nō kekahi hakahaka i ka hoʻohālikelike ʻia me nā ʻāina ʻē.ʻO kekahi o nā pilikia koʻikoʻi ʻo ia ka pitch hoʻokahi.ʻO ka rebar mai ke anawaena o 16 a 40 mm he pitch o 2.5 mm, a ʻo ka pitch 2.5 mm kūpono loa i ke anawaena o 22 mm.Hoʻohui hoʻoikaika.ʻOiai aia nō nā hakahaka ma kekahi mau wahi, e hoʻemi ʻia kēia mau hakahaka i ka wā e hoʻomau ana ka ʻenehana hana lima kila o Kina.

ʻO Yida reinforced conical thread coupler i kēia mau kūlana:

1. ʻAʻohe māwae ma ka ʻili o kamea hui milo conicala ua piha na kaula a aohe hemahema e ae.

 2. Ka nānā pono ʻana o nā niho niho, e nānā i ka pololei o ke ana me ke ana ʻana o ke kaula pololei.

 3. Pono nā ʻili o waho o nā mea hoʻohui milo conical o nā ʻano like ʻole a me nā nui e ʻike maopopo ʻia nā pae rebar a me nā anawaena.

 4. Pono e ho'opa'a 'ia nā puka ma nā wēlau 'elua o ka hui kaula conical me ka uhi 'ilika no ka ho'oma'ema'e a ma'ema'e o loko.

ʻO Yida reinforced steel sleeve/rebar straight thread loaʻa nā pono penei:

 1. ʻAʻole pili ʻia e nā kumu he nui e like me ka haku mele ʻana o ke kila, nā kumu kanaka, ke ea, ka uila, etc.;

 2. ʻAʻohe ona haumia, hoʻokō i nā koi o ka palekana o ke kaiapuni, a palekana a hilinaʻi hoʻi me ka ʻole o ka hana ahi;

 3. ʻO kahi ākea o nā noi, pili i nā ʻano ʻano like ʻole a me ka like, ʻokoʻa ka hoʻohui ʻana i ke anawaena;

 4. ʻO ka ikaika kiʻekiʻe, kūpaʻa a hilinaʻi maikaʻi;

 5. Hana maʻalahi, wikiwiki kūkulu.

I nā makahiki i hala iho nei, ua holomua nui ʻo Kina i ka ʻenehana pili o ka hoʻoikaika ʻana i nā mīkini kila.Hoʻohana nui ʻia nā hui kaula conical i hoʻopaʻa ʻia i ke kila i nā papahana nui e like me nā hale kiʻekiʻe, nā alahaka, nā ala kaʻa kiʻekiʻe, nā mea kanu nuklea, a me nā hale kila.He maʻalahi ka hana ʻana i nā lima lima pili Rebar, ʻaʻohe lapalapa ākea, palekana a wikiwiki hoʻi, a mālama nui i nā kumuwaiwai a me nā limahana.Hoʻohanohano nui ʻia lākou ma Kina a ma waena o ka honua, a hoʻololi mālie i ka ʻenehana rebar kuʻuna a me ka ʻenehana welding.

Hoʻohana nui ʻia ʻo HeBei YiDa e hoʻoikaika ana i ka lima pili kila i nā papahana nui e like me ka hong kong-zhuhai-macao bridge, fuqing nuclear power plant, beijing-shanghai high-speed railway a me wuhan Greenland center.
