Peb cov Ductile Iron Pipe tau tsim los ua kom tau raws li cov qauv siab tshaj uas cov neeg yuav khoom ntseeg siab - tshwj xeeb yog ISO 2531 thiab AWWA C151. Cov no tsis yog cov ntawv xwb; lawv yog cov ntsuas uas qhia rau koj cov neeg yuav khoom tias cov yeeb hlau yuav tuav tau hauv kev siv tiag.​

Peb siv cov hlau ductile zoo siab, nrog lub zog tensile tsawg kawg 420 MPa thiab lub zog yield 300 MPa. Vim li cas qhov ntawd tseem ceeb? Nws txhais tau tias cov yeeb hlau tuaj yeem tiv tau lub siab hnyav thiab kev txav hauv av yam tsis tawg - zoo meej rau cov kav dej lossis cov tshuab khib. Peb muaj cov chaw soj ntsuam thib peb sim nws, thiab nws tiv tau 5000 lub voj voog ntawm kev hloov siab (los ntawm 0 mus rau 1.6 MPa) yam tsis muaj dej tawg.​

Txhua lub yeeb hlau kuj tau txais cov cement mortar lining hauv (tuab 5-10 mm, raws li txoj kab ncaws) los tiv thaiv corrosion los ntawm dej, ntxiv rau cov zinc coating sab nraud (tsawg kawg 130 g/m²) rau kev tiv thaiv hauv av. Peb txawm ua kev sim av corrosive: faus rau hauv av acidic rau 10 xyoo, cov yeeb hlau qhia tias hnav tsawg tshaj 0.1 mm. Rau koj cov neeg yuav khoom, qhov no txhais tau tias ntau xyoo ntawm kev tu tsawg - raws nraim li cov neeg yuav khoom loj nrhiav hauv Ductile Iron Pipe uas ntseeg tau.

Cia kuv qhia koj txog qhov peb ua peb cov Ductile Iron Pipe. Ua ntej, peb muab cov hlau ore ntshiab siab rhiab hauv lub tshuab hluav taws xob 1500°C, ntxiv magnesium kom ua rau nws ductile - cov kauj ruam no yog tswj los ntawm computer, kom cov magnesium ntshav nyob nraim li 0.03-0.08% (qhov zoo tshaj rau lub zog).​

Tom ntej, peb siv txoj kev centrifugal casting: peb spin lub mold ntawm 800-1200 rpm thaum ncuav cov hlau molten. Qhov no tsim cov yeeb hlau tuab, tib yam tsis muaj cua npuas - peb xyuas phab ntsa tuab nrog ultrasonic testing (tolerance ±2 mm) kom paub tias txhua ntu tau raws li qauv. Tom qab casting, peb anneal cov yeeb hlau hauv lub tshuab kub (rhaub kom txog 900°C, ces txias qeeb) kom txo tau brittleness - qhov no ua rau nws 30% yooj yim dua li cov hlau cast ib txwm.​

Tom qab ntawd los ntawm lub lining thiab coating: peb txau cov cement mortar sab hauv nrog lub caj npab neeg hlau (kom tuab sib npaug) thiab nkag sab nraud rau hauv lub dab tshuab zinc. Thaum kawg, peb ua kev sim hydrostatic - peb muab dej puv txhua lub Ductile Iron Pipe thiab ua siab rau 1.5 npaug ntawm lub siab ua haujlwm rau 10 feeb. Yog tias nws tawg ib tee, peb muab pov tseg. Tsis muaj kev luv luv ntawm no - peb paub tias koj cov neeg yuav khoom tsis tuaj yeem them cov yeeb hlau tsis zoo.

Rau cov neeg yuav khoom loj, muaj lub Hoobkas uas tuaj yeem ua kom tau raws li cov kev txiav txim loj yog qhov tseem ceeb - thiab peb muaj peev xwm xa khoom. Tam sim no, peb khiav 4 cov kab centrifugal casting rau Ductile Iron Pipe, nrog txoj kab ncaws los ntawm 100 mm txog 2000 mm. Txhua kab tuaj yeem tsim 80-120 lub yeeb hlau ib hnub, yog li peb lub peev xwm txhua hli ncav 12,000-15,000 meters.​

Peb khaws 500 tons ntawm cov hlau ore thiab 100 tons ntawm zinc hauv peb lub tshuab, yog li peb yeej tsis tshaib cov khoom. Yog tias koj xav tau kev txiav txim loj - hais tias, 5000 meters ntawm 600 mm txoj kab ncaws yeeb hlau - peb tuaj yeem ua tiav hauv 2 lub lis piam. Peb kuj muaj pab neeg logistics tshwj xeeb uas ua haujlwm nrog cov tuam txhab shipping uas tshwj xeeb rau cov khoom hnyav (Ductile Iron Pipe hnyav, yog li peb siv cov thawv reinforced kom tsis txhob puas).​

Nyob rau 3 xyoo dhau los, peb muaj 99.1% kev xa khoom raws sijhawm mus rau Europe thiab America. Peb kuj muab cov ntev tshwj xeeb (3-6 meters, raws li koj qhov kev thov) thiab flange connections - tsuas yog qhia peb 3 hnub ua ntej, thiab peb yuav kho cov kab ntau lawm. Tsis muaj kev tos rau cov khoom me lossis cov kev txiav txim tshwj xeeb ntawm no.​

Peb tsis yog muag Ductile Iron Pipe nkaus xwb - peb xav tsim kev ntseeg siab mus ntev nrog peb cov neeg yuav khoom loj, yog li peb cog lus ruaj khov. Ua ntej, 25 xyoo kev lav: yog tias lub yeeb hlau twg ua tsis tau vim yog cov khoom lossis kev tsim kho tsis zoo hauv 25 xyoo (nyob rau hauv kev siv ib txwm), peb yuav hloov dawb. Qhov no sib pum rau lub neej kev pab uas AWWA pom zoo, yog li koj cov neeg yuav khoom xav tias nyab xeeb.​

Qhov thib ob, cov ntawv qhia qhov zoo uas tsis muaj zais: txhua pawg tuaj nrog daim ntawv pov thawj kuaj (nrog rau lub zog tensile, cov txiaj ntsig kev sim siab, thiab coating tuab) kos npe los ntawm peb tus thawj tswj hwm zoo. Koj tuaj yeem qhia cov no rau koj cov neeg yuav khoom los ua pov thawj tias cov yeeb hlau ua tau raws li ISO/AWWA qauv - tsis muaj kev kwv yees.​

Qhov thib peb, cov lus ceev them nyiaj yooj yim rau cov kev txiav txim loj: peb muab 30% ua ntej, 70% nyiaj tshuav tom qab xa khoom (L/C lossis T/T, raws li koj). Peb kuj muaj pab neeg txhawb nqa technical 24/7 - yog tias koj cov neeg yuav khoom muaj lus nug txog kev teeb tsa (xws li kev txuas flanges) lossis kev tu, peb cov engineers yuav teb hauv 4 teev.
