3. Na-ebuli ya na nko abụọ
Tinye nko 1 na mgbanaka ebuli flange (sket 3-4 site na nsọtụ ndu) na nko 2 na poselin dị n'okpuru flange ma ọ bụ ihe nkwado. Bulite ha abụọ n'otu oge, jiri nwayọọ nwayọọ na-ebuli nko 1 ka ị na-ewetu nko 2 ruo mgbe osisi ahụ dabara na akụkụ elu elu.

 

4. Nduzi waya & akara
Tinye eriri ụzọ eriri site na tube onye na-eduzi, fanye atụdo, wee tinyeghachi okpu n'elu, ọta grading, na bọọdụ ọnụ. Gbaa mbọ hụ na akara nke ọma n'elu. Jikwaa nke ọma iji gbochie mmebi poselin.

 

5. Bolt tightening
Mechie bolts diagonally na nke nta nke nta iji gbochie nrụgide flange na-enweghị isi. Afefela torque akwadoro (20–25 N·m) ka ịzenarị ụgbụgba ọkụ.
