Ihe akara klaasị nke usoro flange B16 pụtara: A na-akpọ ọkwa klaasị dị ka nrụgide anabatara (8750PSI) nke A105, WCB 1.1 otu ihe n'okpuru 454°C na ọkwa nrụgide dabere na 60.3MP:

• P1=(10S/8750)*Pr≤Pc

P1 - ọkwa nrụgide nke flange na okpomọkụ kwekọrọ, mmanya.
S - uru nrụgide ike nke ihe flange, MPa.
Pr – flange klaasị uru.

PC – Ogwe ọkwa nrụgide kacha.

N'ihi na a flange nke ihe 150 # na ikike nrụgide nke 100MPa, ọ dị (10*100/8750)*150=17Bar=1.7MPa.Ọ bụ ihe a na-ekwe ka nrụgide nke 150 # flange, nke ikike ọrụ ikike ya bụ 1.7%.

Usoro maka ikpebi mpaghara Bolt nke usoro flange B16:
Maka njikọ flange ma ọ bụ valvụ ahụ:

• AB *7000Psi≥Ag*Pc-> AB *120MPa≥Ag*Pg

Ab - gafee akụkụ nke bolt
Mpaghara nke Ag gasket kọntaktị elu n'ime na n'èzí dayameta (gụnyere ebe ebu na gasket n'ime dayameta).
