Kuongororwa kweDuctle Iron Pipes
Izvo zvave kupfuura makore makumi manomwe kubva pakugadzirwa kweDuctle Simbi pombi kuma1940. Nesimba rayo rakakwirira kwazvo, eongsation high, kurwisa, kuramba kuvhunduka, zvimwe zvinhu zvakawanda zvakanaka, Ductle Simbi pombi ndiyo yakanakisa munyika yanhasi yekuburitsa mvura uye gasi zvakachengeteka. Ductle iron, inonziwo nodular simbi kana spheroidal graphite simbi, inoonekwa nekuvapo kweiyo sphroidal graphite mumhedzisiro yekukanda.

Mavara eiyo ductle iron pombi
Ductle Simbi pombi inowanikwa mumatare emaraini kubva pa80 mm kusvika 200 mm uye yakakodzera kune ese anotenderera kwemvura uye kugovera (zvinoenderana neBS en 545) uye secentance neBS en 598). Ductle Simbi mapepa ari nyore kujoina, anogona kuiswa mumamiriro ekunze ekunze uye kazhinji pasina kukosha kwekusarudzwa kwekusarudzwa kumashure. Chinhu charo chekuchengetedza chengetedzo uye kugona kwekugara pasi pekufamba kwekuita kuti ive iyo yakanaka pombi zvinyorwa kune dzakasiyana siyana dzekushandisa.
Mamakisi e ductle iron pombi yatinogona kugovera
Tafura inotevera iri kuratidza ese ductle iron zvinyorwa zvemitambo yenyika imwe neimwe.IF iwe uri weAmerican, ipapo unogona kusarudza 60-18, 65-45-12, 70-50-05 etc., kana iwe uchibva kuAustralia, iwe unogona kusarudza 400-12, 500-7, 600-3 nezvimwe.

Ductle Simbi Zvikumbiro
Ductle simbi ine simba rakakura uye kushayiwa pane grey simbi. Zvivakwa izvozvo zvinotendera kuti zvishandiswe zvakanyatsobudirira mune dzakasiyana siyana dzekushandisa maindasitiri, kusanganisira zvipuka, mavhiri emagorodzano, magiramu emapomba, machina mapuranga emhepo, uye zvimwe zvakawanda. Nekuti haina kupwanya kunge grey iron, simbi dire zvakare yakachengeteka kuti ishandise mukukanganisa-dziviriro-dziviriro zvikumbiro, senge bhollards.
