Anawaena inoa a me ke anawaena o loko a me waho o ka paipu kila spiral

Paipu kila wiliwilihe ʻano paipu kila i hana ʻia ma ka ʻōwili ʻia ʻana o ke kaula kila i loko o ke ʻano paipu ma kekahi kihi spiral (anuʻu angle) a laila wili. Hoʻohana nui ʻia ia i nā ʻōnaehana pipeline no ka aila, ke kinoea maoli a me ka lawe wai.

ʻO ke anawaena inoa ke anawaena inoa o ka paipu, ka waiwai helu o ka nui o ka paipu. No ka paipu kila spiral, ua kokoke ke anawaena inoa, aole nae i like me ke anawaena maoli a mawaho paha.

Hōʻike pinepine ʻia e DN me kahi helu, e like me DN200, e hōʻike ana i kahi paipu kila me ke anawaena nominal o 200 mm.

ʻO ke anawaena inoa maʻamau (DN):
1. Ke anawaena liʻiliʻi (DN100 - DN300):
DN100 (4 iniha)
DN150 (6 iniha)
DN200 (8 iniha)
DN250 (10 iniha)
DN300 (12 iniha)

2. Laulā anawaena waena (DN350 - DN700):
DN350 (14 iniha)
DN400 (16 iniha)
DN450 (18 iniha)
DN500 (20 iniha)
DN600 (24 iniha)
DN700 (28 iniha)

3. Ke Anawaena Nui (DN750 - DN1200)
DN750 (30 iniha)
DN800 (32 iniha)
DN900 (36 iniha)
DN1000 (40 iniha)
DN1100 (44 iniha)
DN1200 (48 iniha)

4. ʻOi aku ka nui o ke anawaena (DN1300 a ma luna)
DN1300 (52 iniha)
DN1400 (56 iniha)
DN1500 (60 iniha)
DN1600 (64 iniha)
DN1800 (72 iniha)
DN2000 (80 iniha)
DN2200 (88 iniha)
DN2400 (96 iniha)
DN2600 (104 iniha)
DN2800 (112 iniha)
DN3000 (120 iniha)

ʻO ke anawaena o waho (OD): ʻO OD ke anawaena o ka ʻili o waho o ka paipu kila spiral. ʻO ka OD o ka paipu kila spiral ka nui maoli o waho o ka paipu. Hiki ke loaʻa ka OD ma ke ana maoli, maʻamau i nā millimeters (mm).
Ka Anawaena Kuloko (ID): ʻO ka ID ke anawaena o ka ʻili o loko o ka paipu kila pila. ʻO ka ID ka nui maoli o loko o ka paipu. E helu pinepine ʻia ka ID ma ka unuhi ʻana i ʻelua mānoanoa o ka pā mai ka OD i millimeters (mm) ID = OD-2 x Mānoanoa Pā.

Kahua noi

ʻO nā paipu kila spiral me nā anawaena inoa like ʻole he mau noi like ʻole ma nā ʻano ʻano like ʻole:
1. liʻiliʻi anawaenaPaipu kila Ssaw(DN100 - DN300): hoʻohana maʻamau i ka ʻenekinia kūloko no nā paipu wai, nā paipu hoʻoheheʻe, nā paipu kinoea, etc.
2. anawaena waenaPaipu Ssaw(DN350 - DN700): hoʻohana nui ʻia i ka ʻaila, ka pipeline kinoea kūlohelohe a me ka pipeline wai ʻoihana. 3. nui anawaena spiral kila paipu (DN100 - DN300): maʻamau i hoʻohana 'ia i loko o municipal 'enekinia wai lako paipu, drainage pipeline, kinoea pipeline, etc.
3.Paipu Ssaw Anawaena Nui(DN750 - DN1200): hoʻohana ʻia i nā papahana hoʻoili wai lōʻihi, nā paipu aila, nā papahana ʻoihana nui, e like me ka lawe ʻana i waena.
4. ultra-nui ke anawaenaPaipu hao kalapona Ssaw(DN1300 a ma luna aʻe): hoʻohana nui ʻia no ka wai lōʻihi lōʻihi, ka aila a me ke kinoea pipeline papahana, nā paipu submarine a me nā papahana ʻoihana nui.

ʻO ke anawaena inoa a me nā kikoʻī ʻē aʻe o ka paipu kila spiral e hana pinepine ʻia e like me nā kūlana kūpono a me nā kikoʻī.
1. nā kūlana honua: API 5L: pili i ka pipeline transport steel pipe, e kuhikuhi ana i ka nui a me nā mea e pono ai o ka paipu kila spiral ASTM A252: pili i ka paipu kila structural, kuhikuhi i ka nui a me nā koi hana o ka paipu kila kila.
2. kūlana aupuni: GB / T 9711: pili i ka paipu kila no ka lawe ʻana i ka ʻoihana aila a me ke kinoea, e wehewehe i nā koi ʻenehana o ka paipu kila spiral. gb/t 3091: pili i ka paipu kila welded no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa, e wehewehe i nā ana a me nā koi ʻenehana o ka paipu kila spiral.
