熱電偶保護(hù)管是最大限度延長(zhǎng)熱電偶使用壽命的套管,根據(jù)使用工況選用適合的保護(hù)管料、熱電偶類型及熱電偶整體內(nèi)部結(jié)構(gòu)形式,這樣熱電偶才能在高溫、腐蝕、耐磨等復(fù)雜環(huán)境中保持長(zhǎng)期穩(wěn)定性、高精度、高性價(jià)比和最長(zhǎng)使用壽命。

熱電偶保護(hù)套管對(duì)材料氣密性、機(jī)械強(qiáng)度、穩(wěn)定性、高熱性、耐高溫性、熱強(qiáng)性、耐腐蝕性、耐腐蝕性和一定的耐溫度劇變的性能都有要求,同時(shí)滿足這些性能要求的熱電偶保護(hù)管目前還沒有,通常用不同材料做熱電偶保護(hù)管滿足特定工況的測(cè)溫需求。熱電偶保護(hù)管通常有金屬管和非金屬管兩類,隨著材料技術(shù)和生產(chǎn)工藝的不斷發(fā)展,可供熱電偶廠家和使用單位選用的熱電偶保護(hù)管材料更加豐富,昌暉儀表制造有限公司結(jié)合大量現(xiàn)場(chǎng)應(yīng)用和大家分享不同材料的熱電偶保護(hù)管性能和應(yīng)用。

一、金屬熱電偶保護(hù)管
1Cr18Ni9Ti(1.4841)熱電偶保護(hù)管
1Cr18Ni9Ti是最常用的熱電偶保護(hù)管,用于氧化氣氛、腐蝕性小且長(zhǎng)期使用溫度≤871℃(1600℉)工況;溫度超過899℃另選材質(zhì);1Cr18Ni9Ti抗硫、抗還原性差,不適合在此環(huán)境使用。

常見的K型熱電偶大多使用1Cr18Ni9Ti材質(zhì)保護(hù)管,K型熱電偶偶材的測(cè)溫范圍為0-1300℃,有用戶將普通裝配式熱電偶用于900-1100℃溫度測(cè)量,結(jié)果熱電偶保護(hù)管不耐用,熱電偶使用壽命很短。熱電偶使用壽命的長(zhǎng)短與熱電偶材料性能、偶絲直徑、熱電偶保護(hù)管材料耐溫、耐腐蝕性、耐磨性及產(chǎn)品整體結(jié)構(gòu)等因素有關(guān),整支熱電偶使用壽命是這些因素綜合結(jié)果的體現(xiàn)。

304熱電偶保護(hù)管
304即0Cr19Ni10。304化學(xué)成分與1Cr18Ni9Ti略有不同;304硬度比1Cr18Ni9Ti低;304價(jià)格比1Cr18Ni9Ti便宜;304低溫耐腐蝕性比1Cr18Ni9Ti好;1Cr18Ni9Ti含有抗晶界腐蝕的鈦,熱電偶生產(chǎn)中使用更廣泛。

0Cr25Ni20(1.4841)熱電偶保護(hù)管
0Cr25Ni20(德標(biāo)1.4841)用于氧化氣氛、腐蝕性小且長(zhǎng)期使用溫度≤1038℃(1900℉)工況;0Cr25Ni20抗硫、抗還原性差,不適合在此環(huán)境使用;0Cr25Ni20用于生產(chǎn)高溫氧化環(huán)境中使用的熱電偶。

316L(1.4404)熱電偶保護(hù)管
316L(德標(biāo)1.4404)抗腐蝕性比1Cr18Ni9Ti好,用于長(zhǎng)期使用溫度≤871℃(1600℉)、腐蝕性工況。

316L熱電偶保護(hù)管一般用于食品行業(yè)、磷酸、亞硫酸鹽液、90%濃度以上濃硫酸、氯化物、溴化物等工況使用的熱電偶生產(chǎn)。316L不用于硝酸、氯離子(Cl-)、氟離子(F-)介質(zhì)溫度測(cè)量的熱電偶保護(hù)管;316L也適用于300℃以下各種濃度的H2S,但是的H2S會(huì)使316L熱電偶保護(hù)管發(fā)生應(yīng)力腐蝕(氫脆)開裂的風(fēng)險(xiǎn),故昌暉儀表不建議將316L作為H2S溫度測(cè)量的熱電偶保護(hù)管。

1.4571熱電偶保護(hù)管
德標(biāo)1.4571不銹鋼耐晶間腐蝕,使用溫度≤850℃(1562℉),常用于硫酸、磷酸、蟻酸、醋酸、海綿鈦生產(chǎn)線測(cè)溫?zé)犭娕急Wo(hù)管。

瑞士904L熱電偶保護(hù)管
904L是目前耐硫酸、稀硫酸腐蝕性最好的鋼種,長(zhǎng)期使用溫度≤280℃。

2.4816熱電偶保護(hù)管
氮化氣氛常出現(xiàn)在氮、氮-氫、氨等高溫氣氛中,在該環(huán)境下氮可進(jìn)入金屬總形成金屬氮化物(常為鉻的氮化物),使材料韌性降低或沿晶界開裂。鎳基合金最內(nèi)部氮化不敏感,2.4816是氮化氣氛中最佳的熱電偶保護(hù)管材質(zhì)。

1.4591熱電偶保護(hù)管
材料在硫化條件的高溫下使用,并經(jīng)常冷卻到室溫,處于濕潤(rùn)的含硫的酸性條件下,昌暉儀表一般采用1.4591不銹鋼做熱電偶保護(hù)管,1.4591具有較好的抗硫化作用和耐硫酸腐蝕性能。

高鉻鑄鐵ZGGr28熱電偶保護(hù)管
高鉻鑄鐵可在1050℃長(zhǎng)期使用,具有抗耐磨、耐腐蝕、耐高溫的特點(diǎn),昌暉儀表使用高鉻鑄鐵管生產(chǎn)還原性含硫氣體、硫酸沸騰爐、碳素焙燒爐、有色冶煉爐等測(cè)溫?zé)犭娕肌?br />
2.4859和2.4610熱電偶保護(hù)管
金屬材料暴露在氯(CL)、鹽酸(HCL)或其他含有鹵素的工況,會(huì)產(chǎn)生金屬鹵化物和CL、F的沿晶腐蝕。
①在貧氧的HCL氣氛中,或許會(huì)形成鐵、鎳和鉻的氯化物。2.4859和2.4610即使溫度達(dá)到850℃、10%HCL/H2氣氛中仍具有耐腐蝕能力,昌暉儀表選用2.4859和2.4610作為抗氯化腐蝕的熱電偶保護(hù)管。
②在穩(wěn)定的低氧分壓氣氛下,可以使用純鎳(alloy 200)和Ni-Mo合金(Nicrofer 6928-alloy B-2)作為熱電偶保護(hù)管。

2.4816和2.4889熱電偶保護(hù)管
在含氧的CL2/O2氣氛或氯化物沉淀時(shí),常常能觀察到氯化物致氧化,這是垃圾焚燒爐中的鍋爐管道的主要腐蝕方式。昌暉儀表采用2.4816和2.4889作為垃圾焚燒爐煙氣溫度測(cè)量熱電偶保護(hù)管,具有優(yōu)良的抗腐蝕能力。

2.4633熱電偶保護(hù)管
2.4633能作為CL的氧化性氣氛中使用的熱電偶保護(hù)管,但適合用在貧氧的HCL氣氛。
