ʻOiai ua kapa ʻia nā bellows HDPE-pālua a me PVC ʻelua-wall bellows, akā ma ka hoʻohui ʻana i kahi ʻano like liʻiliʻi, ma nā wahi he ʻokoʻa loa lākou, inā ʻaʻole ʻoe e manaʻoʻiʻo, e nānā wale i ka moʻo liʻiliʻi iā ʻoe e papa inoa i kēia mau ʻokoʻa.

I. UPVC pā kaulua bellows

ʻO ka UPVC pālua-wall bellows, ʻike ʻia hoʻi ʻo PVC-U pālua-wall bellows, he paipu kūikawā me ka paia o loko, corrugated pā waho a me nā paia o loko a me waho i hana ʻia a hana ʻia e ka polyvinyl chloride ma ke ʻano he kumu kumu.He nani ka helehelena o ka paipu, ka hale kūʻokoʻa, ka ikaika kiʻekiʻe, ka paia i loko maʻemaʻe, ka pale ʻana i ka friction liʻiliʻi, ka holo nui ʻana, ʻaʻole pono ke kumu e hana i ke kahua paʻa, māmā ke kaumaha, maʻalahi ka lawelawe ʻana a me ka hoʻonohonoho ʻana, hana wikiwiki;ʻO ka pilina o ke apo Rubber, ke ala hilinaʻi, maʻalahi e hōʻoia i ka maikaʻi o ke kūkulu ʻana;Hoʻopili maʻalahi.Ke kū'ē ikaika i ka hoʻoponopono kūponoʻole;ʻO ke kūpaʻa leakage maikaʻi, ka pale ʻana i ka corrosion i nā ʻano media kemika;ʻAʻohe unahi i ka paipu, ʻaʻole pono e dredge, kanu ʻia ke ola lawelawe ma mua o 50 mau makahiki.

ʻAʻole i haki ka hoʻāʻo ʻana o ka sila, ʻaʻohe hoʻāʻo hopena leakage TIR≤10% apo ʻoʻoleʻa S1≥4KN/㎡, S2≥8KN/㎡ ʻaʻole i haki ke apo, ʻaʻole e hemo nā paia ʻelua mai ka hoʻāʻo ʻana i ka umu me ka ʻole o ka ʻokiʻoki, ka pohā, ka ʻōhū Manning roughness koena n=0.010.

2, HDPE pā pālua corrugated paipu

ʻO ka paipu paʻa paʻa ʻelua HDPE, ʻike ʻia hoʻi ʻo ka polyethylene pālua-pā ʻāwili paipu, he ʻano hou o ka paipu māmā.polyethylene kiʻekiʻe.Loaʻa iā ia nā hiʻohiʻona o ke kaumaha māmā, ke kūpaʻa kiʻekiʻe, ka paʻakikī maikaʻi, ke kūkulu wikiwiki ʻana a me ke ola lōʻihi, a me nā mea ʻē aʻe.A no ka maʻalahi a me ka hilinaʻi o ka pilina, ua hoʻohana nui ʻia ma ka home a ma waho.Nui o ka paipu kaila pani a me ka paipu hao.Nā hiʻohiʻona hana:

ʻO ka HDPE paipu paʻa paʻa paʻa paʻa paʻa maikaʻi loa, ke kūpaʻa ʻelemakule a me ke koʻikoʻi o ke kaiapuni.No ka paipu hikiwawe ka HDPE pa-pālua i hanaia e kona mau mea maka.Penei kona mau waiwai.

ʻO ke kū'ē ikaika i ke kaomi o waho: ʻo ka pā o waho he hale circular corrugated, kahi e hoʻonui nui ai i ke apo stiffness o ka paipu, pēlā e hoʻonui ai i ke kū'ē o ka paipu i ka ukana lepo.Ma kēia hiʻohiʻona o ka hoʻokō ʻana, ʻike ʻia ka maikaʻi o ka paipu corrugated HDPE pālua-pā i ka hoʻohālikelike ʻia me nā paipu ʻē aʻe.ʻO ke kumukūʻai ʻenekinia haʻahaʻa: ma lalo o ke ʻano o ia ukana, ʻo ka HDPE pālua-paʻa corrugated paipu wale nō e pono i kahi pā lahilahi e hoʻokō i nā koi.No laila, ke hoʻohālikelike ʻia me ka paipu paʻa paʻa o nā mea kikoʻī like, hiki iā ia ke mālama ma kahi o ka hapalua o nā mea maka, no laila he haʻahaʻa hoʻi ke kumukūʻai o ka HDPE pālua-wall corrugated pipe.ʻO kēia kekahi hiʻohiʻona koʻikoʻi o ka paipu.

ʻO ka hana maʻalahi: Ma muli o ke kaumaha māmā o HDPE pālua-wall corrugated paipu, ʻoi aku ka maʻalahi o ka lawelawe ʻana a me ka pilina, no laila wikiwiki ke kūkulu ʻana a maʻalahi ka mālama ʻana.Ma lalo o ke kūlana o ka wā kūkulu paʻa a me nā kūlana hana maikaʻi ʻole, ʻoi aku ka ʻike o kona mau pono.ʻO ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi, ka hopena hopena: ʻo ka embrittlement embrittlement o ka HDPE pālua pālua ʻo -70 ℃.ʻAʻole pono nā kūlana haʻahaʻa haʻahaʻa haʻahaʻa maʻamau (ma luna o -30 ℃) e hana i nā hana pale kūikawā i ka wā e kūkulu ʻia ai, kūpono ke kūkulu ʻana i ka hoʻoilo, a ʻo ka HDPE pālua-pā lua corrugated paipu maikaʻi ka hopena.

Paʻa kemika maikaʻi: No ka mea, ʻaʻohe polarity o ka mole HDPE, he paʻa kemika maikaʻi loa.Koe wale no kekahi mau oxidants ikaika, ʻaʻole hiki i ka hapa nui o nā media kemika ke hoʻopau iā ia.ʻAʻole e hōʻino ka lepo, ka uila, ka waikawa a me nā kumu kumu ma ka hoʻohana maʻamau i ka pipeline, ʻaʻohe bacteria, ʻaʻohe scaling, ʻaʻole e emi kona wahi kaʻa me ka piʻi ʻana o ka manawa holo.

Ke ola lōʻihi:

Ma lalo o ke kūlana o ka lā ultraviolet, hiki ke hoʻohana ʻia nā bellow pā pālua HDPE ma mua o 50 mau makahiki.Hiki ke flexural iki ka lōʻihi o ka HDPE pālua-paʻa corrugated paipu axial, ʻaʻole i hoʻopilikia ʻia e kekahi degere o ka noho ʻole ʻana ma ka ʻāina, hiki ke waiho pololei ʻia ma kahi ʻāpana pololei ʻole a pēlā aku.Pono:

1, hale kūʻokoʻa, ikaika kiʻekiʻe, paʻa kūʻē i ka hopena, maʻalahi ka pā, ʻoi aku ka nui o ka friction;Hoʻopili ʻoluʻolu o ka launa pū ʻana, ʻaʻohe leakage.

2, ke kaumaha māmā, ka wikiwiki o ke kūkulu ʻana, nā koina hana haʻahaʻa, nā kumukūʻai haʻahaʻa.

3, polyethylene hydrocarbon polymer mole i loko o ka acidic a me ka alkaline i kanu ʻia i ke ola no nā makahiki ʻoi aku ma mua o 5, a he ʻōmaʻomaʻo, non-toxic, non-corrosive, ʻaʻohe scaling.

4, māmā kaumaha, hana wikiwiki, ho'ēmi i nā kumukūʻai.

5, kanu ʻia ke ola lawelawe ma mua o 50 mau makahiki.

ʻOiai he mau māhoe ʻelua, ʻoiai he ʻano like loa lāua ma nā ʻano a pau, e ʻike nā mākua, i ka hihia o kēia mau puʻupuʻu pālua ʻelua ʻaʻole he māhoe, he ʻike maʻalahi ia, a inā mākou i ʻike lawa e pili ana iā lākou. , hiki iā mākou.
