Apa Kupon Korosi?

Kupon korosi minangka alat sing gampang lan efektif, sing digunakake ing ngawasi lan analisa tarif karat ing pipo, tank, utawa struktur logam liyane. Iki cilik, standarisasi, potongan logam persegi. Kejabi, ana uga kupon bunder.
Kupon Korosi minangka potongan tes logam standar sing digantung ing wadhah tes utawa diselehake langsung ing situs kasebut kanggo ngawasi exchange Excour Excuing utawa pipa tes. Tujuane yaiku kanggo ngawasi utawa ngevaluasi kahanan korosi saka sistem banyu pendinginan. Biasane, spesimen logam wis diobati lan ditimbang sadurunge diselehake ing sistem uji coba kanggo wektu tartamtu (kayata 30 nganti 90 dina), sawise dicopot kanggo mriksa kahanan karat. Dheweke banjur di resiki lan ditimbang kanggo nemtokake tingkat karat taunan (diukur ing MILS saben taun, ing ngendi 1 mph = 0,0254mm / A), jinis karat, lan ambane saka piala, lan ambane. Data sing dipikolehi saka kupon logam dipengaruhi ora mung medium korosif, nanging uga faktor kayata perawatan kupton, lokasi penempatan, lan metode metalurtual.

The installation of a corrosion coupon within a system is a methodical process. Typically, the coupon is inserted into the pipeline using a holder or probe, which is installed via a flange or welding process. This installation is not random but is carried out strategically, with the coupon usually positioned in the lower third of the pipeline. The insertion depth is often two-thirds of the pipeline’s diameter, aligning the coupon within the most active corrosion zone to accurately represent the corrosive conditions within the system.

Nanging, penempatan coupon sing tepat bisa beda-beda gumantung saka spesifik piping, kalebu ukuran, karakter aliran, lan sifat produk kasebut. Pertimbangan ati-ati diwenehake kanggo faktor kasebut kanggo mesthekake coupon kasebut kena kahanan sing padha karo sistem internal.

It’s crucial to note that while the coupon should be inserted deep enough to accurately gauge corrosion rates, it should not touch the bottom of the pipeline. This careful balance in placement ensures the coupon can effectively monitor the corrosive conditions without interfering with the system’s operation.

Apa Kupon Korosi AC AC?

Kupon korosi AC / DC minangka kupon corrosion khusus sing dirancang khusus kanggo ngawasi lan nganalisa pengaruh saka loro gantian saiki lan saiki (DC) ing tarif korosi utawa struktur logam liyane.

Corrosion in pipelines can be influenced by various factors, including the presence of electrical currents. Stray electrical currents, both AC and DC, can exacerbate corrosion, leading to a phenomenon known as “electrolytic” or “electrochemical” corrosion.

Panjelasan ringkes babagan loro:

• Korosi AC: AC, utawa gantian saiki, karat bisa kedadeyan nalika pipo ana ing jarak cedhak karo garis listrik tinggi. AC saka garis-garis tenaga iki bisa mlebu menyang pipa, nyebabake karat kanthi cepet ing titik-titik ing endi saiki godhong pipa kanggo bali menyang lemah.
• Korosa DC: DC, utawa langsung langsung, karat bisa kedadeyan nalika pipa kasebut kapapar ing arus DC Stray. Iki bisa kedadeyan ing pipeline sing ana ing cedhak ril-daya sing dikerjakake DC utawa amarga ngembangake sistem perlindungan katol cathodik.

Kepiye carane Korrosi?

Kupon Korosi kerja adhedhasar prinsip sing gampang: padha kapapar ing kahanan pipa, tank, utawa sistem liyane amarga bahan-bahan sing dikarepake kanggo ngetung tingkat karat ing sistem kasebut.

Akses pas kanggo kupon currosion

Pas Akses EMT direkayasa kanggo nggampangake ngawasi karat lan erosi ing lingkungan proses tekanan. Ngidini kanggo sisipan sing aman lan ngilangi piranti ngawasi nggunakake alat spesialis, ngilangi kebutuhan sing larang utawa isolasi sauntara. Pas Akses iki cukup serbaguna kanggo ngrampungake sisipan lan mbusak kupon karat, probi korosi, lan probes erosion. Peralatan khusus bisa diwenehake miturut panjaluk.

Prinsip kerja kupon korosi

The corrosion evaluation method primarily used for coupons is the mass loss method. To obtain meaningful and measurable mass loss data, an extended exposure period may be necessary. For analysis and determination of the corrosion rate, the coupon must be removed from the plant or equipment (note: if the coupon is to be re-exposed, its removal and cleaning may affect the corrosion rate). These devices can only provide cumulative historical information. For example, after 12 months of exposure, stress corrosion cracking might be found on a coupon, but it’s impossible to determine when the crack began or what special conditions caused the onset and development of the crack. Importantly, the crack propagation rate cannot be accurately estimated because the start time of the crack is unknown. The cleaning, weighing, and microscopic inspection of coupons generally require a significant amount of labor. The use of coupons does not easily simulate the effects of wear corrosion and heat transfer on corrosion.

Napa nggunakake Kupon Korosi?

Kupon koroon digunakake kanggo sawetara sebab, utamane kanggo ngawasi lan ngatur tarif korosi ing sistem industri kayata pipa, tank, lan sumur minyak. Mangkene sawetara sebab utama kenapa Kupon Korosi digunakake:

1. Pangopènan ramalan: Kanthi rutin ngawasi tarif karat nggunakake kupon, sampeyan bisa ngira-ngira urip sisa sistem sampeyan. Iki ngidini sampeyan jadwal pangopènan utawa panggantos sadurunge gagal.
2. Ngevaluasi langkah kontrol karat: Yen sampeyan nggunakake inhibitor korosi utawa cara kontrol karat liyane, sampeyan bisa nggunakake Kupon kanggo ngukur efektifitas. Yen tarif karat suda sawise ngetrapake langkah kontrol, iki nuduhake manawa ukuran kontrol efektif.
3. Ngenali jinis karat: Penampilan fisik saka coupon sing corroded bisa menehi pitunjuk babagan jinis karat sing kedadeyan. Contone, currosion pitting nyebabake bolongan cilik ing kupon, nalika karang seragam nyebabake tipis saka material.
4. Ngawasi biaya sing efektif: Kupon koroon cukup murah kanggo ngasilake lan nginstal, nggawe cara sing larang kanggo ngawasi karat.
5. Versatility: Kupon bisa digawe saka materi logam, saéngga bisa digunakake ing macem-macem lingkungan lan sistem.
6. Ngerteni mekanisme cubrosion: Kupon bisa nyedhiyakake data sing larang regane sing mbantu ngerteni mekanisme korosi ing play, lan giliran, pangerten iki bisa menehi informasi babagan desain strategi kontrol karat kasar korporsi sing luwih efektif.

Ringkesan

Kesimpulane, Kupon Korosi duwe peran penting kanggo ngawasi lan ngatur tarif karat ing macem-macem sistem industri. Dheweke nawakake cara sing larang lan serbaguna kanggo ngira-ngira efektifitas langkah kontrol karat, prédhiksi umur peralatan, lan ngenali jinis karat.
