DIN 17100 St52.3 Rectangular Structural Steel Pipe Pre-shipment Inspection

Amapayipi ensimbi akhiwe ngonxande e-DIN 17100 St52.3 athunyelwa e-Australia.

I-DIN 17100 isetshenziswa ngokujwayelekile ezingxenyeni zensimbi, imigoqo yensimbi, izinduku zocingo, nemikhiqizo eyisicabangaphandle komthungokanye nezingxenye ezihlanganisiwe, eziyisikwele nezingunxande, izinto zokubumba, kanye nemikhiqizo eqediwe kancane ezinsimbini ezijwayelekile zesakhiwo ezilethwa esimweni esishisayo esakhiwe noma esijwayelekile ngemva kokukhiqizwa.

I-St52.3 ingenye yamamaki, futhi inombolo yezinto ezibonakalayo ingu-1.0570.

Ngaphambi kokulethwa, iBotop ihlela ukuthi abasebenzi abangochwepheshe bekhwalithi bahlole ngokucophelela imikhiqizo ukuqinisekisa ukuthi ikhwalithi yomkhiqizo ihlangabezana ngokugcwele nezidingo zamakhasimende.

Okokuqala, ikhwalithi yobuso, ububanzi, ukuphakama, ubude, isikwele, kanye nezinye izilinganiso zokubukeka kwepayipi lensimbi lesakhiwo kuyahlolwa ngokucophelela ukuqinisekisa ukuhambisana nezindinganiso kanye nezidingo zamakhasimende.

Okulandelayo, kuhlolwa izakhiwo zamakhemikhali nezemishini zepayipi lensimbi lesakhiwo.

I-EN 17100 St52.3 inezidingo ezilandelayo zokwakheka kwamakhemikhali:

Ibanga	Ukwakheka kwamakhemikhali ngo-% ngobuningi.
	C						P	S	Izinto ezengeziwe ezihlanganisa i-nitrogen (isib. okungenani 0.020% Al kuya ku-total)
	ukujiya komkhiqizo ngo-mm
	≤16	＞16 ≤30	＞30 ≤40	＞40 ≤63	＞63 ≤100	＞100

Ukwakheka kwamakhemikhali kwe-St52.3 kulinganiswa nge-spectrometer, futhi konke okuqukethwe yizinto kuhlangabezana nezidingo zamakhasimende uma kuqhathaniswa nezidingo ezifanele.

Izakhiwo zemishini ze-EN 17100 St52.3 zifaka phakathi amandla okudonsa kanye namandla okukhiqiza, okulinganiswa ngokuhlolwa kokudonsa.

Ngemva kokuphothula konke ukuhlolwa nokuqinisekisa ukuthi ikhwalithi iyahlangabezana nezidingo ezijwayelekile, kukhishwa iSitifiketi Sokuhlolwa Kwezinto (i-MTC). Ngemva kwalokho, kwenziwa amalungiselelo okuthunyelwa kwempahla nemisebenzi ehlobene nayo.

Kusukela yasungulwa ngo-2014, iBotop Steel isibe ngumhlinzeki ohamba phambili wamapayipi ensimbi yekhabhoni enyakatho yeShayina, eyaziwa ngenkonzo yayo enhle kakhulu, imikhiqizo esezingeni eliphezulu, kanye nezixazululo eziphelele.

Ku-oda ngalinye, i-Botop ihlala inamathela kusu lekhwalithi ethembekile namanani amahle, ikhetha thina ukuthi sikunikeze imikhiqizo yamapayipi ensimbi ethembekile.

Isikhathi sokuthunyelwe: Okthoba-11-2024
