Sistemụ Flange Pipe
Ọkpụkpọ ọkpọkọ na-ezo aka na flange ejiri maka ọkpọkọ na ntinye pipeline, ma na-ezo aka na ntinye na ntinye nke akụrụngwa mgbe ejiri ya na akụrụngwa. Enwere oghere na flanges, na bolts na-eme ka flange abụọ ahụ jikọọ nke ọma. A na-eji gaskets mechie flanges. A na-ekewa flange ahụ n'ime njikọ eriri (njikọ eriri) flange, flange ịgbado ọkụ na mwekota flange. A na-eji flanges na ụzọ abụọ, enwere ike iji flange waya maka pipeline dị ala, yana flanges welded maka nrụgide karịa kilogram anọ. A na-agbakwunye gasket n'etiti flange abụọ ahụ wee mechie ya na bolts. Ọkpụrụkpụ nke flanges nwere nrụgide dị iche iche dị iche iche, na bolts ha na-eji dịkwa iche. Mgbe ejikọtara nfuli mmiri na valvụ na pipeline, akụkụ nke akụrụngwa na akụrụngwa ndị a na-eme ka ọ bụrụ ụdị flange kwekọrọ, nke a na-akpọkwa njikọ flange.
