Amapayipi ensimbi amnyamaamapayipi ensimbi angaphekiwe. Ipayipi lensimbi elimnyama, eliqanjwe nge-scaly, i-iron oxide enamathelayo emnyama ebusweni balo. Isetshenziselwa izinhlelo zokusebenza ezingadingi insimbi yama-galvanized.
Ngemva kokufaka inani elincane lenhlanganisela efanelekile emicu, ifakwa epayipini elinentambo. Amapayipi amakhulu ama-diameter ashiselwe, awafakwa ngemicu. Ipayipi lensimbi elimnyama lisikwa nge-heavy duty pipe cutter, i-chop saw noma i-hacksaw. Ungathola futhi amapayipi ensimbi athambile e-ERW amnyama, asetshenziswa kakhulu ekusabalaliseni igesi ngaphakathi nangaphandle kwekhaya, kanye nokujikeleza kwamanzi ashisayo kumasistimu obhayela. Ingasetshenziselwa ukuphuza amanzi noma ukukhipha noma ukukhipha amapayipi. Phequlula Ipayipi lethu Lokwakha kanye nekhathalogi yeshubhu ukuze uthole umphakeli ohlangabezana nezidingo zakho. Ipayipi lensimbi elimnyama lisetshenziselwa izinhlelo zokusebenza ezingadingi ukugaya ipayipi. Leli payipi lensimbi elimnyama elingenazinsimbi liqanjwe ngokumbozwa kwalo kwe-iron oxide emnyama ebusweni balo. Ngenxa yamandla epayipi lensimbi elimnyama, lisetshenziselwa ukuletha igesi yemvelo namanzi ezindaweni zasemaphandleni, kanye nokuvikela izintambo zikagesi namapayipi okuletha isitimu nomoya wokucindezela okukhulu. Imboni ye-oilfield nayo isebenzisa amapayipi amnyama ukuthutha uwoyela omningi ezindaweni ezikude.

Amapayipi ensimbi amnyama namashubhu angasikwa futhi ahlanganiswe ukuze afanele iphrojekthi yakho. Ukufakwa kwalolu hlobo lwepayipi kuyinsimbi emnyama ethambile (ethambile). Ngemva kokufaka inani elincane lenhlanganisela efanelekile emicu, ifakwa epayipini elinentambo. Amapayipi amakhulu ama-diameter ashiselwe, awafakwa ngemicu. Ipayipi lensimbi elimnyama lisikwa ngesisiki sepayipi esindayo, isaha noma hacksaw. Ungathola futhi amapayipi ensimbi athambile e-ERW amnyama, asetshenziswa kakhulu ekusabalaliseni igesi ngaphakathi nangaphandle kwekhaya, kanye nokujikeleza kwamanzi ashisayo kumasistimu obhayela. Ingasetshenziselwa ukuphuza amanzi noma ukukhipha noma ukukhipha amapayipi. Phequlula ikhathalogi yethu yamashubhu okwakha ukuze uthole umphakeli ohlangabezana nezidingo zakho.

Ukuthuthukiswa kwamapayipi ensimbi amnyama

Indlela kaWhitehouse yacwengisiswa nguJohn Moon ngo-1911. Ubuchwepheshe bakhe benza abakhiqizi bakwazi ukudala ukugeleza okuqhubekayo kwamapayipi. Wasebenzisa ubuchwepheshe bakhe ukwakha imishini futhi izitshalo eziningi ezikhiqizayo zakwamukela. Kwabe sekufika isidingo samapayipi ensimbi angenamthungo. Amashubhu angenamthungo ekuqaleni akhiwa ngezimbobo zokubhoboza maphakathi nesilinda. Kodwa-ke, kunzima ukubhola ngokunemba okudingekayo ukuze uqinisekise ukufana kodonga. Ukuthuthukiswa kwango-1888 kukhuphule ukusebenza kahle ngokuphonsa amabhilidi ezizungeze izitini ezingashi. Ngemuva kokupholisa, susa isitini, ushiye imbobo phakathi.

Ukusetshenziswa kwepayipi lensimbi emnyama

Amandla epayipi lensimbi elimnyama akwenza kube kuhle ukudlulisa amanzi negesi yemvelo ezindaweni zasemakhaya nasemadolobheni, kanye nokuvikela izintambo zikagesi namapayipi athwala isitimu somoya kanye nomoya. Amapayipi ensimbi amnyama asetshenziswa imboni kawoyela ne-petroleum ukuthutha uwoyela omningi ezindaweni ezikude. Lokhu kuyazuzisa ngoba ipayipi lensimbi elimnyama lidinga ukulungiswa okuncane. Okunye ukusetshenziswa kwamapayipi ensimbi amnyama kuhlanganisa ukusatshalaliswa kwegesi ngaphakathi nangaphandle kwekhaya, imithombo kanye nezinhlelo zokukhucululwa kwendle. Amapayipi ensimbi amnyama awakaze asetshenziswe ukuthutha amanzi okuphuza.

Ubuciko besimanje bamapayipi ensimbi amnyama

Intuthuko kwezesayensi iyithuthukise kakhulu indlela yokwenza amapayipi ashiselwe izinqe eyasungulwa yi-Whitehouse. Ikhono lakhe kuseyiyona ndlela eyinhloko yokwenza amapayipi, kodwa imishini yesimanje yokukhiqiza ekwazi ukukhiqiza amazinga okushisa aphakeme kakhulu nezingcindezi zenza ukukhiqizwa kwamapayipi kuphumelele kakhulu. Kuye ngobukhulu bawo, ezinye izinqubo zingakhiqiza ipayipi elishiselwe ngenani elimangalisayo lamafidi angu-1 100 ngomzuzu. Ngokukhula okukhulu kwezinga lokukhiqizwa kwamapayipi ensimbi, izinga lomkhiqizo wokugcina nalo liye laba ngcono.

Ukulawulwa Kwekhwalithi Yepayipi Lensimbi Elimnyama

Ukuthuthukiswa kwemishini yokukhiqiza yesimanje kanye nokusungulwa kwemikhiqizo ye-elekthronikhi kube nomphumela wokuthuthuka okukhulu ekusebenzeni kahle nokulawulwa kwekhwalithi. Abakhiqizi banamuhla basebenzisa ama-X-ray gauge akhethekile ukuqinisekisa ukufana kodonga. Amandla weshubhu ahlolwe ngomshini ogcwalisa ithubhu ngamanzi ngaphansi kwengcindezi ephezulu ukuze kuqinisekiswe ukuthi ithubhu ibanjwe endaweni. Amapayipi ahlulekile azolahlwa.

Insimbi engaphekiwe

Ukusetshenziswa okuyinhloko kwepayipi likathayela ukuthutha amanzi ezindlini nasezindlini zentengiso. I-Zinc iphinde ivimbele ukunqwabelana kwezimbiwa phansi ezingavala amapayipi amanzi. Amapayipi anamagalani avame ukusetshenziswa njengezinhlaka zezikafula ngenxa yokumelana nokugqwala kwawo.

ipayipi lensimbi emnyama

Ipayipi lensimbi elimnyama lihlukile epayipini likathayela ngoba alinawo ama-coating. Umbala omnyama uvela ku-iron oxide eyakha endaweni yayo ngesikhathi senqubo yokukhiqiza. Ukusetshenziswa okuyinhloko kwamapayipi ensimbi amnyama ukuthutha i-propane noma igesi yemvelo eya ezakhiweni zokuhlala nezohwebo. Ipayipi lakhiwe ngaphandle kwemithungo, okwenza kube umsele ongcono wokuthutha amagesi. Ipayipi lensimbi elimnyama liphinde lisetshenziswe ezinhlelweni zokufafaza umlilo ngenxa yokuthi alikwazi ukumelana nomlilo kunepayipi likathayela.

Isingeniso Somehluko

• Womabili amapayipi amnyama nakathayela enziwe ngensimbi.
• Amapayipi othayela anezinki, kanti amapayipi amnyama awanawo
• Ngenxa yokuthi kulula ukugqwala, amapayipi amnyama afaneleka kakhulu ukuthutha igesi. Ngakolunye uhlangothi, amapayipi ama-galvanized angcono kakhulu ukuthwala amanzi, kodwa hhayi inhlanhla
• Amapayipi othayela abiza kakhulu ngoba ane-zinc coating
• Ipayipi elakhiwe ngothayela lihlala isikhathi eside

Amanzi negesi kudingeka kufakwe amapayipi emabhilidini okuhlala abantu kanye nezohwebo. Izitofu zamandla egesi yemvelo, izifudumezi zamanzi nezinye izinto zikagesi, kuyilapho amanzi ebalulekile kwezinye izidingo zabantu. Izinhlobo ezimbili ezivame kakhulu zamapayipi asetshenziselwa ukuthutha amanzi negesi amapayipi ensimbi amnyama namapayipi ensimbi.

Inkinga
I-zinc esemapayipini anothayela ingaqhuma ngokuhamba kwesikhathi, ivale amapayipi. Ukuqhuma kungabangela ukuthi ipayipi liqhume. Ukusetshenziswa kwamapayipi othayela ukuthutha igesi kungaba yingozi. Ngakolunye uhlangothi, amapayipi ensimbi amnyama agqwala kalula kunamapayipi anothayela futhi avumela amaminerali avela emanzini ukuba akheke kuwo.

Izindleko
Amapayipi ensimbi abiza ngaphezu kwamapayipi ensimbi amnyama ngoba ukukhiqiza amapayipi afaka uthayela kuhilela inqubo yokufaka uthayela nokukhiqiza. Izinsimbi ezifakwe amagalani nazo zibiza ngaphezu kwalezo ezisetshenziswa ezinsimbini ezimnyama. Amapayipi ensimbi ayisithako akumele axhunywe kumapayipi ensimbi emnyama ngesikhathi kwakhiwa izakhiwo zokuhlala noma ezohwebo.

Uyini umehluko phakathi kwe-astm a53 ne-astm a106?
Umehluko phakathiIpayipi le-ASTM A53futhiIpayipi le-A106ngokwemibandela yobubanzi bokucaciswa, ukwakheka kwamakhemikhali epayipi, izakhiwo zemishini (i-tensile namandla esivuno, njll.), uhlobo lwepayipi.

ububanzi

• I-ASTM A53 iwukucaciswa okujwayelekile kwepayipi, insimbi, okucwilisiwe okumnyama nokushisayo, okufakwe uthayela, okushiselwe, nokungenamthungo.
• I-ASTM A106 iwukucaciswa okujwayelekile kwepayipi lensimbi elingenamthungo lesevisi yokushisa okuphezulu.

Uhlobo Lokusebenza A 53钢管
ingashiselwa noma ingabi namthungo, kuye ngokuthi ithengwe kanjani. Kuwukucaciswa kwepayipi lensimbi elijwayelekile, okuhlanganisa ipayipi elinothayela kanye nepayipi elimnyama.
I-A106 iyipayipi elifana namakhemikhali kodwa isevisi yezinga lokushisa eliphezulu (kufika ku-750 degrees Fahrenheit). Ishubhu elingenamthungo.
E-US okungenani, ipayipi elishiselwe ngokuvamile line-A53, kuyilapho i-A106 ingenamthungo. Uma ucela i-A53 e-US, bazocaphuna i-A106 njengenye indlela.
Ukwakheka Kwamakhemikhali
Isibonelo, uma siqhathanisa i-A106-B ne-A53-B engenamthungo ngombono wokwakheka kwamakhemikhali, sithola:

• 1. I-A106-B iqukethe i-silicon, ubuncane. 0.10%, lapho i-A53-B ingu-0%, i-silicon iyisici esibalulekile sokuthuthukisa izinga lokumelana nokushisa.
• 2. I-A106-B iqukethe i-manganese engu-0.29-1.06%, lapho i-A53-B ingu-1.2%.
• 3. I-A106-B iqukethe isulfure ephansi ne-phosphorus, ubuningi. 0.035%, lapho i-A53-B iqukethe u-0.05 no-0.045%, ngokulandelanayo.

A53 Tube vs A106 Tube – (4) Mechanical Properties

Omunye umehluko phakathi kwepayipi le-A53 nepayipi le-A106
Ngenxa yokuthi banezigaba ezihlukene futhi bacacisa izinhlobo ezahlukene zamapayipi ensimbi, inqubo yokukhiqiza kanye nokuhlolwa kokulawulwa kwekhwalithi okudingekayo kanye nokuhlolwa kuzohluka komunye nomunye. Uma unombono othize, sicela ushiye amazwana.
