Nā Pōmaikaʻi o ka Paipu Kila ʻo A252 Grade 2 Spiral Submerged Arc Welded Polypropylene Lined Pipe

 Paipu i hoʻopaʻa ʻia me ka polypropyleneHāʻawi ia i kekahi mau pono ke hoʻohana ʻia me ka wiliwili i hoʻopaʻa ʻia i loko o ka paipu kila A252 Grade 2. ʻO kekahi o nā pono nui ka pale ʻana i ka pala e hele mai me ka polypropylene. Ma ka uhi ʻana i ka paipu kila me ka polypropylene, ua pale ʻia ka ʻili o loko mai nā mea palaho, e hōʻoiaʻiʻo ana i ka lōʻihi a me ka hilinaʻi o ka ʻōnaehana paipu. He mea nui loa kēia i nā noi kahi i hōʻike ʻia ai nā paipu i nā kemika ʻino a i ʻole nā ​​​​kūlana kaiapuni.

Eia kekahi, ua ʻike ʻia nā paipu i hoʻopaʻa ʻia me ka polypropylene no ko lākou ʻili laumania o loko, e kōkua ana i ka hōʻemi ʻana i ka friction a hoʻonui i ke kahe ʻana o ka wai i loko o nā paipu. Hoʻonui kēia i ka pono a hoʻemi i ka hoʻohana ʻana i ka ikehu, e lilo ia i koho hoihoi no nā ʻano hana ʻoihana a me nā ʻoihana like ʻole.

ʻO kekahi pono nui o ka hoʻohana ʻana i ka paipu polypropylene i hoʻopaʻa ʻia i loko o ka wiliwili submerged arc, ʻo ia ka pale hou aku mai ka ʻaʻahu ʻana. Hana ka lining polypropylene ma ke ʻano he pale, e pale ana i nā paipu kila mai ka hōʻino abrasive a hōʻemi i ka pono no ka mālama pinepine a me ka hoʻoponopono ʻana.

Ma waho aʻe o nā pono i hāʻawi ʻia e ka lining polypropylene, ʻo ke kaʻina hana hoʻoheheʻe arc submerged spiral kekahi mea nui i ka hoʻokumu ʻana i kahi ʻōnaehana paipu paʻa a hilinaʻi hoʻi e hoʻohana ana.Paipu kila A252 Papa 2Hoʻohana kēia ʻenehana kuʻihao i kahi kaʻina hana kuʻihao arc flux-cored e hana ana i nā kuʻihao ikaika a laumania e hoʻokō ana i nā kūlana kiʻekiʻe e pono ai no nā paipu ʻoihana.
