Njikọ flange pipeline na mkpuchi ụgbọ mmiri nrụgide na ụlọ ọrụ mmanụ na gas na-arụ ọrụ n'okpuru nrụgide dị elu, oke okpomọkụ, na mgbasa ozi na-emebi emebi. Ihe mkpuchi na gburugburu ndị a ga-enwerịrị ụkpụrụ ASME B16.5 na ASTM A193/A194.

• ASTM A193 B7 stud bolts (Cr-Mo alloy steel) - ọkọlọtọ ụlọ ọrụ maka njikọ flange dị elu.
• Mkpụrụ hex dị arọ 2H (ASTM A194) - jikọtara ya na studs B7 maka flanges gosiri nrụgide.
• Incoloy / super-alloy bolts - akọwapụtara maka ọnọdụ ọrụ na-emebi emebi ma ọ bụ ihe mkpuchi

Nchekwa corrosion maka bolts dị elu

Nrụrụaka bụ isi ihe na-ebute ọdịda ngwa ngwa na-akabeghị aka n'èzí na gburugburu ụlọ ọrụ mmepụta ihe. Ịhọrọ ọgwụgwọ elu dị mma dị mkpa - karịsịa maka bolts dị elu ebe hydrogen ebrittlement sitere na electroplating bụ ezigbo ihe ize ndụ karịa ọkwa 10.9.

• Ihe mkpuchi dacromet - mmiri na-adabere na mmiri, nke na-enweghị chromate, 480-1000 + h na-eguzogide nnu-spray; nchekwa maka ọkwa 10.9/12.9 bolts
• Luxubao (zinc-flake) mkpuchi - yiri Geomet/Delta-Tone; magburu onwe ya maka ike ifufe na ihe owuwu dị arọ
• Hot-mikpu galvanizing - adabara ọkwa 8.8 na n'okpuru; A naghị atụ aro ya karịa ọkwa 10.9 n'ihi ihe egwu hydrogen
• Zinc electroplating - nhọrọ akụ na ụba maka ime ụlọ ma ọ bụ obere mkpughe gburugburu
