Nnukwu dayameta flange dị ka a na-ahụkarị flange, n'ihi na ọ nwere ike tinye n'ọrụ a dịgasị iche iche nke dị iche iche oge na uru nke ezi mmetụta nke ụlọ ọrụ hụrụ n'anya, ngwaahịa na-ọtụtụ-eji ígwè na chemical ụlọ ọrụ na ndị ọzọ na ụlọ ọrụ, ka DHDZ flange emepụta ka ewebata. ụkpụrụ mgbakọ chọrọ na mgbochi corrosion ewu.

I. Mgbakọ ụkpụrụ na chọrọ nke nnukwu dayameta flanges
1. Mgbe ị na-agbakọta otu ụzọ flanges, oghere mkpuchi nke oghere ndị na-arị elu kwesịrị ka ọ kwekọọ na oghere nke na-adaba na flanges ndị a na-edozi ma na-ejikọta ya na flanges. Ndịiche ekwesịghị ịbụ ihe karịrị 1.5 na 2mm nke mpụta dayameta nke flanges.
2. Lelee ma mezie flange ọnọdụ site n'aka ekpe na aka nri na 90 square ụkwụ, na imecha ntụpọ ịgbado ọkụ na idozi nnukwu dayameta flange site atọ na anọ ebe mgbe ntụpọ ịgbado ọkụ.
3. Mgbe ị na-ahọrọ flanges dabara adaba nke akụrụngwa ma ọ bụ mgbakọ valve, ekwesịrị ilebara anya iji hụ ma flanges nke akụrụngwa mbụ ma ọ bụ mgbakọ valve bụ otu ihe eji eme ya na pipeline.
4. Mgbe ị na-agbakọta flanges dị larịị, a ga-etinye njedebe ọkpọkọ 2/3 nke ọkpụrụkpụ nke n'ime dayameta nke flange ahụ, wee hụ weld flange na ọkpọkọ. Maka ọkpọkọ kwụ ọtọ, hụ weld site n'elu, wee lelee ọnọdụ flange calibration site n'akụkụ dị iche iche nke nwere 90 square ụkwụ nke mere na akara akara dị n'ahịrị ọkpọkọ etiti, wee hụ weld n'okpuru ebe ntụpọ.
5. Tupu ikpokọta flange ahụ, hichaa flange elu, karịsịa akara mkpuchi.

Abụọ, usoro ọrụ na njirimara nke nnukwu dayameta flange mgbochi corrosion ewu
Akara ihe mgbochi corrosion maka njuputa flange nke nnukwu dayameta. Tapawa mpempe akwụkwọ (transperent) teepu n'akụkụ flange iji gbochie flange ahụ ka ọ ghara ịdị unyi mgbe ị na-etinye ihe mgbochi corrosion; Jiri ihe mgbochi corrosion mechie ma jupụta mkpochapụ flange iji hụ na mkpochapụ flange juputara na inhibitor corrosion inhibitor.
Mgbe emejuchara oghere flange ahụ na ihe mgbochi corrosion, jiri ihe nchacha putty mee ka ihu ya dị nro n'akụkụ ntụzịaka okirikiri, nke mere na oghere na ọnụ flange n'otu ụgbọ elu. Kpochapụ akụkụ abụọ nke teepu ahụ.
Ọ bụrụ na ị na-eji flange anticorrosion ude, ị kwesịrị iji mma bechapụ flange anticorrosion ude n'ime warara ibe, na mgbe ahụ dị ka obosara nke flange ọdịiche, ozugbo mejuo flange oghere site n'aka. Pịa ala mgbe ị na-ejuputa.
Mwepu na ọgwụgwọ elu nke nnukwu flange dayameta. Wepu nchara na mkpochapụ flange na kposara na ahịhịa; Mkpochapụ flange dị ọcha na ikuku abịakọrọ; Ọ bụrụ na ejiri ihe mkpofu kemịkal mee ihe, nyochaa ma ihe na-ewepụ kemịkal ọ ga-emetụta akara flange.
Ọ bụrụ na enwere obi abụọ, a na-atụ aro ka ị ghara iji usoro kemịkal; Jiri aja aja ma ọ bụ yarn hichaa flange elu iji zute ọkọlọtọ ST2.
