kiʻiʻoniʻoni noʻonoʻo pale 8
9-Uku uku
Kiʻi 1 Kiʻikuhi kumu kumu
2.2 hoʻohālikelike
2.2.1 Ma muli o ke 'ano o ke kaula huli wela, hiki ke mahele 'ia i:
A) Paipu huipuʻu huikau hoʻopaʻa wela hoʻohaʻahaʻa iho i ka wela uila;
B) ka paipu huikau mana mau.
2.2.2 E like me nā mea ʻokoʻa ʻokoʻa o ka paipu laʻana, hiki ke māhele ʻia i:
A) polyvinylidene fluoride (PVDF) paipu hui;
B) Polyperfluoroethylene propylene (FEP) paipu hui;
C) hoʻoheheʻe polytetrafluoroethylene (PFA) paipu hui;
D) polytetrafluoroethylene (ivory PTFE) paipu hui;
E) ke kila kila (0Cr17Ni12Mo2) paipu hui.
2.3 kükohu
2.3.1 ʻO ka hōʻuluʻulu kumu hoʻohālike o nā huahana paipu hoʻohuihui e hoʻokomo i nā mea ma lalo iho nei:
A) He anawaena o waho, i millimeters (mm);
B) Ke anawaena o waho o ka paipu laʻana, ma ka millimeters (mm);
C) Ka helu o nā paipu laʻana;
D) mea hoʻoheheʻe ʻia;
E) Ka wela hana (℃);
F) Nā ʻano o nā uwea huli wela, me ka huli ʻana i ka wela uwila hoʻopaʻa ponoʻī a me ka huli ʻana i ka wela uila mana mau.
3. Penei ke kumu hoʻohālike o ka paipu hui:
Hoʻolauna o nā hiʻohiʻona maʻamau
La'ana 1: 'O ka helu kükohu 'o FHG36-8-b-120-Z, 'o ia ho'i, he 36 mm ka anawaena o waho, he 8 mm ka anawaena o waho, he 1 ka helu. ʻO ka perfluoroethylene propylene (FEP) ka mea, ʻo 120 ℃ ka mahana hana ma ka sampling tube, a ʻo ke kaula huli ʻana i ka wela he paipu hoʻohui ponoʻī.
La‘ana 2: ‘O ka helu kumu ho‘ohālike ‘o FHG42-10(2)-c-180-H, e hō‘ike ana he 42 mm ke anawaena o waho o ka paipu la‘ana, he 10 mm ka helu. 2, hiki ke hoʻoheheʻe ʻia ka polytetrafluoroethylene (PFA) ka mea hana, ʻo ka mahana hana ma ka sampling tube he 180 ℃, a ʻo ke kaula hoʻomehana he pahu hoʻohui mana mau.
La‘ana 3: ‘O ka helu kŘkohu FHG42-8-6(2)-c-200-H, e hō‘ike ana he 42 mm ke anawaena o waho o ka paipu la‘ana d1, a he 8 mm ke anawaena o waho. ʻO ka helu o ka pahu sampling d2 he 6 mm, a ʻo ka sampling tube i hana ʻia me ka soluble polytetrafluoroethylene (PFA), ʻo ka mahana hana i loko o ka sampling tube he 200 ℃, a ʻo ka wela tracing cable ʻo ia ka mana mau.
La‘ana 4: ‘O ka helu kŘkohu FHG45-8(2)-6(2)-f-250-H, e hō‘ike ana he 45 mm ka anawaena o waho, he 8 ka anawaena o waho o ka paipu la‘ana d1. mm, a ʻo ka helu he 2, a ʻo ke anawaena o waho o ka pahu sampling d2 he 6 mm, a ua hana ʻia ka pahu sampling me ke kila kila (0Cr17Ni12Mo2), a ʻo ka mahana hana ma ka sampling tube he 250 ℃, me ka huli ʻana i ka wela.
He paipu hui pumehana
