Ngā Tohu Hua

He tirohanga whānui mō ngā pereti nikara Cryogenic

He tino pai ngā pereti nikara cryogenic mō ngā mahi e pāngia ana e ngā pāmahana tino iti. Ka whakamahia mō te kawe i te hau māori wai (LNG) me te hau hinu wai (LPG).
A 645 Gr A / A 645 Gr B, he whakaiti utu me te whakapiki i te haumaru i roto i te hanganga tāke ethylene me te LNG.
Mā ngā whare hanga hou e taea ai e mātou te hanga maitai A 645 Gr A me Gr B me ngā maitai nikara 5% me te 9% tikanga.

● LNG
Ka whakarewaina te hau māori i te pāmahana tino iti o te -164 °C, ka whakaitihia tōna rahinga mā te 600 tau. Mā tēnei ka taea te penapena me te kawe me te whai hua hoki i te taha ōhanga. I ēnei pāmahana tino iti, me whakamahi ngā maitai nikara motuhake 9% kia pai ai te ngāwari me te ātete ki te pakarukaru. Ka tukuna e mātou he pereti whānui rawa atu ki tēnei wāhanga mākete, ahakoa he matotoru tae atu ki te 5 mm.

● LPG
Ka whakamahia te tukanga LPG hei whakaputa i te propane me ngā hau tukatuka mai i te hau māori. Ka waimeha ēnei hau i te pāmahana rūma i te pēhanga iti, ā, ka rongoatia ki roto i ngā tāke motuhake i hangaia ki te 5% maitai nikara. Ka tukuna e mātou ngā pereti anga, ngā pane me ngā kōne mai i te pūtake kotahi.

Hei tauira, tangohia te Pereti ASTM A 645 Gr B

● Mā te whakamahinga o te A 645 Gr A mō te hanga tāke ethylene ka piki ake te kaha, ka piki ake te haumaru, ā, ka taea hoki te whakaiti i te matotoru o te pakitara hei penapena nui i ngā utu mō te hanganga tāke.
● Ka tutuki i te ASTM A 645 Gr B ngā āhuatanga rauemi e rite ana ki ērā o ngā maitai nikara tuku iho 9% i roto i te rokiroki LNG engari e tutuki ana i ēnei whakaritenga me te iti iho o te ihirangi nikara tata ki te 30%. Ko tētahi atu hua ko te whakaiti nui i ngā utu i roto i te hanga o ngā tāke LNG o uta me te tai, me te hanga o ngā tāke wahie LNG.

Kounga teitei mō te taumata haumarutanga teitei

Ko te pūtake o ā mātou pereti nikara kounga teitei ko ngā pereti parakore teitei mai i tā mātou ake wheketere hanga maitai. Ko te iti rawa o te waro e whakamana ana i te kaha whakarewa tino pai. Ko ētahi atu painga kei roto i te kaha pānga pai o te hua me ngā āhuatanga pakaru (CTOD). Ka whakamatautauria te mata katoa o te pereti ki te ultrasonic. Kei raro iho i te 50 Gauss te aukume toenga.

Te tukatuka i mua hei whakatutuki i ngā whakaritenga motuhake a te kiritaki

● I pania ki te onepu, i pania rānei ki te onepu, ā, i whakakīia ki te paraihe.
● Te whakarite i ngā tapa whakarewa: Nā te iti o te ihirangi waro ka taea te whakaiti i te whakapakeketanga o te taha kua wera.
● Te piko o te pereti.
