E hoʻouna i ka noi

Hoʻohana nui ʻia ka Underground Direct Buried Insulated Steel Pipe i loko o nā ʻupena wai a me ke kinoea hoʻoili paipu, nā papahana hoʻoheheʻe paipu kemika i ka ʻaila, kemika, ka wela waena a me ka ʻuena wela, nā paipu hoʻoheheʻe ʻana i ka ea waena, a me ka ʻenekinia aupuni.

ʻO Underground Direct Buried Insulated Steel Pipe he paipu kila -kunu mua ʻia me ka maikaʻi o ka hoʻokaʻawale ʻana i ka wela, ka palekana a me ka hilinaʻi, a me ke kumu kūʻai haʻahaʻa.

Hōʻike

1. Hiki ke pale i ka wela a hiki i ka 140 degere c ka paipu kila i hoopiliia mamua.

2. Me ka corrosion kū'ē HDPE kapa komo paipu hiki ke hana i ka paipu pololei kanu ma lalo o ka 'ole auwaha.

3. Hiki i nā paipu nui like ʻole a me nā paipu paipu ke lawelawe no ka papahana hoʻomehana a me ka hoʻoluʻu like ʻole.

4. Hiki ke hoʻolālā ʻia ka mānoanoa polyurethane foam mai 26.5-83mm a ʻoi aku paha.

Nā hiʻohiʻona huahana

Paipu kila hana

ʻO ka papa kumu, ka mea e lawe ai i ke kikowaena (e like me ka wai wela a i ʻole ka mahu), ua hana ʻia me ka -kiʻekiʻe o ka maikaʻi ʻole a i ʻole ka paipu kila i hoʻoheheʻe ʻia a wiliwili ʻia a pono e hoʻokō i nā kūlana paipu kaomi (e laʻa, 100% nānā radiographic).

Hoʻomākaʻi

ʻO ka pahu polyurethane ʻoʻoleʻa (density 60-80 kg/m³) ka mea mua, e hāʻawi ana i ka haʻahaʻa haʻahaʻa haʻahaʻa (0.013-0.03 kcal/m:h· degere ) a me ka -cell ratio ʻoi aʻe ma mua a i ʻole like me 90%, e hōʻemi pono ana i ka nalowale wela. No nā noi wela -kiʻekiʻe (e like me nā paipu mahu), ua hoʻohana ʻia kahi ʻano hoʻopulapula ʻano hoʻoheheʻe i hoʻopaʻa ʻia (me kahi ʻāpana hoʻoheheʻe alumini alumini) e hāʻawi ana i ka pale wela o 150 degere -450 degere.

Paipu waho

High-density polyethylene (HDPE) or steel-in-steel (double-layer steel pipe structure) provides corrosion resistance, waterproofing, and mechanical protection. The HDPE outer pipe requires corona treatment on the inner surface, has a density >940 kg/m³, and a tensile strength >20 MPa. Hoʻohana ke kaʻina hana i ka hana prefabrication a me ka hoʻopili ʻana i hoʻohui ʻia, me ka wehe ʻana i ka ʻōpala o nā paipu kila, ka hoʻopiha piha ʻana o ka papa insulation, a me ka hoʻopili ʻana o nā paipu pale i waho e hōʻoia i ka paʻa paʻa ʻana o nā papa ʻekolu.

Nā Pōmaikaʻi Hana Nui

Hoʻoikaika ikaika

He 25% wale nō ka pohō wela o nā paipu kuʻuna, a ʻoi aku ka liʻiliʻi o ka wela ma ka pūnaewele pipeline ma mua o 2% (ʻoi aku ka maikaʻi ma mua o ka pae honua o 10%).

Noho lōʻihi a me ka pale ʻana

Hoʻokaʻawale ka paipu waho HDPE/Fiberglass i ka makū o ka ea, ka hopena i ka haʻahaʻa haʻahaʻa o ka corrosion rate no ka paipu kila hana, ka hopena o ke ola o 30-50 mau makahiki (3-4 mau manawa o nā paipu kahiko).

ʻAʻole wai a me ka mākū -Hōʻoia

He haʻahaʻa ka nui o ka komo ʻana o ka wai (ma kahi o 0.2 kg/m²) ka pahu polyurethane cell paʻa, a ʻo ka hoʻolālā sila awa ke pale aku i ka hū ʻana o ka wai i ka wā o ke kūkulu ʻana.

Ka nānā ʻana i ka palekana

ʻIke pololei ʻia ka leak i kūkulu ʻia-i loko.

Kukulu waiwai

Hoʻemi ʻia ka ʻeli ʻana ma luna o 50% a ua hoʻemi ʻia ka hoʻohana ʻana i ke konima e 90%. ʻO ka hana mua ʻana o ka hale hana i hui pū ʻia me ka ʻauwaha ma -wahi e hoʻopōkole ai i ka manawa hana ma o 50%.

Nā noi pili

Pumehana waena/hoʻoluʻu, hoʻouna mahu -mahana kiʻekiʻe, petrochemical, mea kanu wela. ʻO ka hoʻomehana ʻāpana, nā pipeline ʻoihana e like me nā lāʻau lapaʻau, kemika, a me nā paipu aila.

Nā kikoʻī

Anawaena inoa inoa	DN20-DN1600.
Kaha kaomi	ʻO ke kaomi inoa ʻoi aku ka liʻiliʻi a i ʻole like me 2.5 MPa (kahi kumu kumu{1}}pili pili).
Kaulana wela	He emi a like paha me ka 120 degere (peak 140 degere) no ka hoʻomehana maʻamau, a hiki i ka 450 degere no nā paipu mahu.

Ko makou Hale Hana

Aia ʻo Hebei Yugang Pipe Manufacturing Co., Ltd. ma ka Yanshan Economic Development Zone ma Cangzhou, i loko o ka puʻuwai o ka ʻoihana pipeline o North China. Hoʻokumu ʻia i ka makahiki 2005, ua hoʻonui ʻia ka hui ma 2014 i kahi hui piha e hoʻohui ana i ka ʻenehana pipeline, nā lako hana, a me nā mea hana. Ua loaʻa i nā ʻenehana hou i ka makahiki 2024 ka ʻike ʻia ma ke ʻano he -ʻoihana ʻenehana kiʻekiʻe. Aia i loko o kāna mau huahana nui nā paipu kila pale -corrosion no ka aila a me ke kinoea, nā paipu wiliwili spiral, nā paipu insulated, a me nā mea pono. Ua lako ka hui me na laina hana paipu spiral elima, ekolu laina hana paipu anti-corrosion, eono laina hana paipu insulated, a me elua laina hana paipu humuhumu pololei, me ka nui o 300,000 tona. Hoʻopaʻa ʻia ka hui ʻo ISO9001, a hoʻokō kāna mau huahana me nā kūlana honua API Spec 5L/5CT/5B.
