1. I loko o 50 mika o ka hoʻokomo ʻana o ka hui insulation, e pale i nā lua make e welded.

2. Ma hope o ka hoʻopili ʻana o ka hui insulated i ka pipeline, ʻaʻole ʻae ʻia e hāpai i ka pipeline i loko o 5 mau mika o ka hui.Pono e hoʻāʻo ʻia ke kaomi me ka pipeline.

3. Ma hope o ka hoʻopili ʻia ʻana o ka hui insulation i ka pipeline, pono e hoʻoponopono ʻia ka hui e like me ka mea e pono ai, a ʻaʻole ʻae ʻia ka mahana o ka ʻili o ka insulation ma mua o 120℃i ka wā anti-corrosion hana.

4. I ka hoʻokomo ʻana i ka hui insulating, pono e hoʻokomo ʻia ma nā ʻaoʻao ʻelua o ka hui ma ka ʻāpana paipu pololei 20 mau mika mai ka kuʻekuʻe a hoʻonohonoho i ka bracket.Pono e pale ʻia ka hoʻokomo ʻana ma lalo o ka lepo i ka wai perennial.

5. Pono e hoʻokomo ʻia ka mamao axis waena o ka hui ma ka laina pololei like me ka mamao axis waena o ka pipeline, a ʻaʻole pono e ʻoi aku ka mamao o nā axis waena ma mua o 0.2mm i ka wā e hoʻokomo ai.

6 I ka neʻe ʻana o ka pipeline≥ʻo ka nui o ka uku o ka hui insulation, pono e hoʻonui ʻia ka helu o nā hui e like me ka neʻe ʻana.ʻAʻole pāpā ʻia ka hoʻoponopono ʻana i ka nui o ka ʻae ʻana o ka pipeline i hiki ai i ka hui insulation ke ʻano o ka palena o ka hoʻoneʻe ʻana a me ka neʻe ʻana, ʻae ʻia ma mua o ka palena ( Expansion, displacement, deflection, etc.).

7 I ka wā o ka hui insulating i kahi kiʻekiʻe a i hoʻokuʻu ʻia paha i ka lewa, pono e hoʻopaʻa ʻia ka pipeline ma ka hanger, bracket, a i ʻole heleuma.ʻAʻole ʻae ka hui insulating i ka hui e amo i ke kaumaha a me ka ikaika axial o ka pipeline ponoʻī, inā ʻaʻole pono e hoʻolako ʻia ka hui me kahi mea anti-pull-off (kona hiki ke lawe).Pono e ʻoi aku ma mua o ka ikaika axial o ka paipu).
