Pambuka
Kubah Korosi bisa digunakake kanggo nyoba tingkat karat ing industri sing beda, kayata industri minyak lan gas lan industri banyu. Kupon karat sing bisa ditarik EMT-RCC teka karo alat pengetahuan sing ndadekake supaya bisa njupuk coupon loro kanggo padie kanthi tekanan. Tekanan sing dirancang ing ngisor 10 MPA. Sajrone operasi, ambane implantasi kupon korosi bisa diatur kanggo nampung diameteripun lan kekandelan tembok. Sistem standar kasedhiya ing macem-macem dawa 24, 30, 36, 48 inci (kanggo nyukupi kabutuhan pelanggan) -making cocog kanggo pipa diameter sing beda. Kupon karat karat sing bisa ditarik maneh saka kalebu coupon korosi, katup bola, lan kit clamp safety sing bisa luwes. Apike kanggo nggunakake penutupan safety nalika tekanan pipa nyelehake ing ngisor 1500 PSI lan suhu tiba ing ngisor 500 ° F.
Understanding the Test Results: Take the Water System as An Example
The corrosion rate of a coupon is determined by the amount of metal lost over a specified period. To determine metal loss, the coupons are meticulously weighed and reported before and after. Corrosive “pitting” is also quantified by measuring the area of the pitted surface.
Location, exposure length, pH, water temperature, coupon design or placement, flow velocity, and current water treatments are all factors that influence the corrosion rate.
Following the evaluation, the technician will compute the rate in mils per year. Each metal or alloy has a different allowable corrosion rate.

Components of EMT Retractable Corrosion Coupons
| Majelis Clamp Safety | This part guarantees that the system is securely attached to the pipeline. It is intended to withstand the system’s high pressure and temperature conditions. |
| Lock Nut | The lock nut is critical in locking the system and preventing it from loosening due to pipeline vibration or pressure variations. |
| Nut Sealing | The sealing nut, in conjunction with the lock nut, forms a secure and tight seal, preventing pipeline leakage. |
| Pipa Sambungan | Iki minangka potongan sistem sing nyambung kupon korosi menyang pipa. Iki dibangun kanggo tahan tekanan lan suhu sing padha karo pipa. |
| Full Bore Ball Valve | Aliran media pipeline dikontrol dening katup iki. Sampeyan bisa mungkasi utawa ngidini aliran lengkap, sing kritis kanggo perawatan lan operasi sistem. |
| Base Welded | Dasar sing dilas dadi dhasar sistem Kupon, nyedhiyakake platform sing kuat lan stabil kanggo komponen liyane. |
| Kupon Mounting Rod | Rod iki njamin kupon korosi lan bisa luwes kanggo macem-macem diameter pipa lan kekandelan tembok. |
| Nut Imbuhan | Nut penyesuaian ngidini coupon currosion supaya posisi persis ing pipo. Iki penting kanggo entuk data karat sing tepat. |
| Clamp Safety Ndhuwur | Clamp iki nempatake bagean ndhuwur sistem lan bisa digunakake ing clamp aman kanggo njamin sistem kasebut kanthi aman ing pipa. |
| Nut Ngunci | Nut ngunci nambahake lapisan pangayoman tambahan kanggo sistem kanthi njamin manawa modifikasi posisi coupon tetep tetep sajrone operasi. |
| Clamp Safety Lower | Clamp iki ngamanake bagean ngisor sistem, kolaborasi karo clamp aman sing luwih dhuwur kanggo menehi sambungan sing ketat lan aman menyang pipa. |
Instalasi maneh saka Kupon Korosi Retractable EMT-RCC
Nalika panggantos coupon korosi rampung utawa diinstal sawise mriksa, nerusake ulang piranti kupon. Nerusake ulang maneh saka piranti coupon nalika panggantos coupon korosi rampung utawa diinstal maneh sawise karya pemeriksaan.
(1) Priksa kanggo ndeleng apa rod imbuhan ana ing posisi.
Jarak antarane rong clamping safety kudu diukur lan diatur (l2 = 515525mm). Yen ora cocog karo kahanan iki, mula kudu diatur. (CATETAN: Sajrone prosedur penyesuaian, tetep stasioner clamp safety sing luwih murah lan mung nyetel clamp aman.)
(2) Ganti senyawa panyegel.
Mbusak materi panyuntakan saka benang pipa cabang lan nut saling, banjur bungkus bahan panyusangan anyar ing benang.
(3) Sambungake piranti coupon.
Sambungake piranti coupon nganggo benang pipa cabang, kenceng tangan nganti ora obah, banjur ngencengi nut nut nganggo bengok.
(4) Nguripake katup.
Priksa bocor ing sambungan pipa cabang lan sambungan sing benang sawise mbukak katup. Nutup katup yen ana bocor, banjur ngatasi segel bocor (ganti bahan utawa ngganti bagean, dijaga, lan nginstal maneh). Yen isih ana bocor, baleni proses iki nganti ora ana bocor.
(5) ngasilake clamp aman kapital kanggo posisi asli.
Nyetel nut panyesuaian ngisor clamp aman kanggo posisi paling murah sanalika bisa mengaruhi penyesuaian nut imbuhan ndhuwur. Kanggo jarak rekaman instalasi asli L, nyetel jarak ing antarane clamp aman lan lumahing pangkalan sing dilas; Deleng langkah 4 instalasi dhisikan. Nalika kenceng kacang, siji wong bisa milih ngencengi rong kacang, utawa wong loro bisa ngencengi rong kacang kasebut bebarengan, usaha njaga celana keamanan ndhuwur kanggo nyegah miring kakehan supaya ora kakehan miring.
(6) Snap coupon ndhukung rod menyang papan.
Sawise nyetel clamp aman ndhuwur, verifikasi arah rodha kupon kupon lan dipateni kaya indikasi area indikasi ing arah aliran mili pipeline. Ngencengi kacang-kacangan larutan ndhuwur lan ngisor ing clamp aman ndhuwur, lan mriksa lan ngencengi nut kunci kunci celah sing luwih murah. Instalasi rampung.
Proses mbalekake saiki wis rampung.
