Amapayipi ensimbi engagqwali e-ASTM A312 304L 316L 6mtr angenamthungo, ampunga amhlophe, afakwe i-pickled
Ipayipi lensimbi engagqwaliiwucezu olude olungenalutho lwensimbi ye-alloy engagqwali. Ingxenye yayo eyinhloko yinsimbi, equkethe okungenani i-10.5% chromium (Cr). Izinto ezifana ne-nickel (Ni) kanye ne-molybdenum (Mo) zivame ukungezwa ukuthuthukisa izakhiwo ezithile. Izici zayo ezivelele kakhulu ukumelana kwayo nokugqwala kanye ne-oxidation okumangalisayo, ngenxa yefilimu eqinile engashukumi eyakhiwe ebusweni bayo, evumela ukusetshenziswa kwayo kabanzi ezindaweni ezinomswakama, ezigqwala ngamakhemikhali, noma ezishisa kakhulu. Ipayipi lensimbi engagqwali liphinde linikeze amandla amahle kakhulu, ukuqina, ukuhlanzeka (kulula ukuhlanza nokubulala amagciwane), kanye nokusebenza kahle komshini kanye nokushintshwa. Izinto ezivamile zifaka izinsimbi ezingagqwali ze-austenitic ezifana ne-304 (inhloso ejwayelekile) kanye ne-316 (emelana nokugqwala kakhulu, equkethe i-molybdenum). Ukusetshenziswa kwayo kuhlukahlukene kakhulu, kufaka phakathi ukuhlobisa kwezakhiwo (izinsika, izinsika zokuvikela), ukuthuthwa koketshezi (amanzi, igesi, imithombo yamakhemikhali), ukucubungula ukudla neziphuzo, amadivayisi ezokwelapha, ukukhiqizwa kwezimoto, izimboni zamandla (uphethiloli, amandla enuzi), izimpahla zasekhaya, kanye nezinsimbi zokunemba. Kuyinto ebalulekile ebalulekile embonini yanamuhla nasempilweni. Ukwelashwa kwendawo okufana nokupholisha kanye nokuqhuma kwesihlabathi kungasetshenziswa ukuhlangabezana nezidingo zobuhle nokusebenza kahle. Sekukonke, amapayipi ensimbi engagqwali ayizinto zamapayipi ezithandwa kakhulu ezindaweni eziningi ngenxa yokuqina kwawo, inhlanzeko, ubuhle, kanye nokuguquguquka kwawo.

Ukumelana Nokucindezela Okumelana Ne-asidi 316 304 Ipayipi Lensimbi Engagqwali Eligoqekile Elingenamthungo 201
Ipayipi lensimbi engagqwaliiyinto yensimbi eyindilinga ende engenalutho, esetshenziswa kabanzi emipayipini yezimboni efana ne-petroleum, amakhemikhali, ezokwelapha, ukudla, imboni elula, izinsimbi zemishini, kanye nezingxenye zesakhiwo semishini. Ngaphezu kwalokho, uma amandla okugoba kanye nokugoba efana, isisindo silula, ngakho-ke sisetshenziswa kabanzi ekwenziweni kwezingxenye zemishini kanye nezakhiwo zobunjiniyela. Isetshenziswa kakhulu futhi efenisha kanye nezitsha zasekhishini.

Ipayipi Lensimbi Engagqwali Elingamelani Nokushisa Le-ASTM Elisezingeni Eliphezulu 431 631 Ishubhu Lensimbi Engagqwali
Amapayipi ensimbi engagqwali enziwe ngensimbi engagqwali enokuqukethwe kwe-chromium okungu-≥10.5% (njengamazinga ajwayelekile angu-304 no-316L). Anamandla aphezulu (amandla okudonsa angu-≥515MPa), ukumelana okuhle kakhulu nokugqwala (ifilimu yokuphambuka kobuso imelana nokugqwala kwe-asidi/usawoti) kanye nokuphepha okuhlanzekile (ukuphela kobuso bezinga lokudla okungu-Ra≤0.8μm). Akhiqizwa ngezinqubo zamapayipi okugoqa okubandayo noma okushiswa ngesivinini esiphezulu futhi asetshenziswa kabanzi kumapayipi amakhemikhali (316L amelana ne-asidi), izakhiwo zokwakha (ama-keel odongeni angamakhethini angu-304), imishini yezokwelapha (amapayipi ahlanzekile aqondile) kanye nemishini yamandla (amapayipi okudlulisa okushisa aphansi kakhulu e-LNG). Yizinto eziyisisekelo eziyinhloko emkhakheni wokukhiqiza okuphezulu.
