Kulimba + kusinthasintha + kuyandama - Paipi yodulira ya CDSR imathandiza kupititsa patsogolo kayendedwe ka madzi

Mu ntchito za uinjiniya wa m'madzi, ntchito zodulira, payipi yodulira ya CDSR yakhala chisankho chofunikira kwambiri mumakampani chifukwa cha kapangidwe kake kapadera komanso magwiridwe antchito abwino kwambiri. Zinthu zazikulu zomwe zili mu mndandandawu zikuphatikizapo mapaipi achitsulo oyandama, mapaipi oyandama ndi mapaipi oyandama opindika, omwe aliwonse ali ndi kapangidwe kabwino kwambiri pazochitika zinazake zogwiritsidwa ntchito.

 

Msana wa mayendedwe abwino

Thechitoliro chachitsulo choyandamandiye chinthu chachikulu chomwe chimagwiritsidwa ntchito mu mndandanda wa CDSR. Chimapangidwa ndi chitoliro chachitsulo, thupi loyandama, chivundikiro chakunja ndi zolumikizira za flange mbali zonse ziwiri. Zipangizo zazikulu za chitoliro chachitsulo ndi Q235, Q345, Q355 ndi chitsulo cha alloy chosatha kusweka. Kapangidwe kameneka kamapereka zinthu zambiri zabwino kwambiri:

1. Ubwino wa kapangidwe kake: kulimba bwino, chitoliro cholunjika, kuyenda bwino

2. Kukana kuvala: Yopangidwa ndi chitsulo chapamwamba kwambiri, imakhala ndi kukana kuvala bwino

3. Kutumiza bwino: koyenera kakang'ono ka kukangana ndi kukana kochepa kopereka

4. Kusintha kwa kupanikizika:lonsekuthamanga kwa ntchitomtunda

5. Mphamvu ya makina: mphamvu yolimba yokoka ndi kuuma

6. Makhalidwe oyandama: Ili ndi magwiridwe antchito abwino oyandama ndipo imatha kuyandama pamwamba pa madzi ikamagwira ntchito

7. Kukhazikika: mphamvu yokoka, kukhazikika bwino pakugwira ntchito, kukana mphepo yamphamvu ndi mafunde

 

Chitoliro chachitsulo choyandama chimagwiritsidwa ntchito makamaka pakuyandamamapaipi, ndipo amafunika kulumikizidwa mosinthana ndi mapayipi a rabara kuti akwaniritse zosowa za kupindika mapaipi. Kutha kwake kunyamula ndi kwabwino kwambiri ndipo kumatha kunyamula zinthu zosiyanasiyana:

- Imatha kunyamula madzi a m'nyanja, madzi abwino ndi matope, dongo ndi mchenga wokhala ndi mphamvu yokoka pakati pa 1.0 ndi 2.0

- Ndi cAmagwiritsidwanso ntchito kunyamula madzi osakaniza (kapena madzi a m'nyanja), miyala, miyala yosweka ndi miyala yamchere ya coral, kuyambira 1.0 g/cm³ mpaka 2.3 g/cm³

 

Yankho lotsika mtengo lotha kuyandama

Thechitoliro choyandamandi chinthu chothandizira chomwe chapangidwa mwapadera kuti chipereke chithandizo cha kuyandama. Chimapangidwa ndi chitoliro chachitsulo, thupi loyandama, chivundikiro chakunja ndi mphete zosungira mbali zonse ziwiri. Zipangizo zazikulu ndi Q235, thovu la PE, NR. Poyerekeza ndi zoyandama wamba, chili ndi ubwino waukulu:

1. Kapangidwe kake: kulimba bwino, kolunjika-kudzera mu payipi,zosavuta kuyika

2. Kugwira ntchito bwino:iT ili ndi magwiridwe antchito abwino oyandama ndipo imatha kupereka mphamvu yayikulu yotsalira

3. Kulimba:ekukana nyengo bwino komanso kukana mphepo ndi mafunde amphamvu

4. Zachuma: kuchuluka kwa magwiritsidwe ntchito, kumatha kusinthidwa ndikugwiritsidwanso ntchito

 

Kugwiritsa ntchito chitoliro choyandama n'kosavuta kwambiri. Chikayikidwa pa chitoliro chachitsulo (chitoliro chachikulu chotulutsira matope), chiyenera kukhazikika pakati kuti chikhale chofanana komanso chokhazikika bwino.chitoliro chachitsuloChimodzi mwa zinthu zake zazikulu ndi kuthekera kwake kugwiritsidwanso ntchito - pamene chitoliro chachitsulo chomwe chimagwiritsidwa ntchito kunyamula matope ndi mchenga chawonongeka ndi kusweka, chitoliro chachitsulo chowonongekacho chikhoza kuphwanyidwa.rAkachotsedwa, chitoliro choyandama chingasungidwe ndikuyikidwa pa chitoliro chatsopano chachitsulo kuti chigwiritsidwenso ntchito.

Poyerekeza ndi ma PE buoys wamba, ma payipi oyandama amakhala okhazikika bwino, opirira kugwedezeka kwambiri komanso opirira kukalamba, komanso amakhala ndi moyo wautali kwambiri, zomwe zimapangitsa kuti akhale abwino kwambiri.,chisankho chotsika mtengo komanso chothandiza pa ntchito za nthawi yayitali.

 

Akatswiri mu kusintha kwa zinthukulumikizanaon

Thepayipi yoyandama yopapatizaakhoza kusintha momwe amagwirira ntchito pokumba mapaipi amadzi posintha momwe amagawidwira. Kapangidwe kake ka kuyandama ndi SG1.6. Zinthu zake ndi izi:

1. Chitetezo cha ntchito: mphira wosagonjetsedwa ndi UVchivundikiro, kukana kuvala kwambiri, ndi kuvalakusonyezamtundu wosanjikiza

2.Kusinthasintha: kusinthasintha kwabwino komanso ngodya yayikulu yopindika

3. Makhalidwe amphamvu: kuthamanga kwa ntchito zosiyanasiyana, mphamvu yolimba komanso kuuma

 

TMapayipi oyandama opangidwa ndi apere amagwiritsidwa ntchito makamaka m'zigawo za mapaipi zomwe ziyenera kupindika, ndipo ali ndi zochitika zosiyanasiyana zogwiritsidwa ntchito:

● Amagwiritsidwa ntchito polumikizakuyandamandi mapaipi apansi pa madzi

● Amagwiritsidwa ntchito ngati chitoliro chakumbuyo cholumikizira cha chodulira chodulira

● Yogwiritsidwa Ntchitoas chimodzipayipi yopukutira utasya chokokera chokokera chotsamira

Yosavuta kugwiritsa ntchito komanso yosinthika kuzinthu zosiyanasiyana zovuta zogwirira ntchito

 

Mapulogalamu ogwirizana - kukulitsa luso

Mitundu itatu ya ma CDSR dredging paipi ili ndi mphamvu zake ndipo nthawi zambiri imagwiritsidwa ntchito mogwirizana m'mapulojekiti enieni kuti ipindule kwambiri:

1. Chitoliro chachitsulo choyandama chimagwiritsidwa ntchito ngati chitoliro chachikulu chonyamulira katundu, chomwe chimagwira ntchito zonyamulira katundu m'magawo ambiri olunjika.

2. Chitoliro choyandama chimagwiritsidwa ntchito ngati chipangizo chothandizira kuyandama kuti chitsimikizire kuti chitoliro chachikulu cha matope chikuyandama bwino

3. Paipi yoyandama yopapatiza imagwira ntchito yofunika kwambiri pazigawo zomwe ziyenera kupindika

 

Njira yogwiritsira ntchito pamodziyi sikuti imangotsimikizira kuti mayendedwe ndi abwino, komanso imakwaniritsa zofunikira pakusinthasintha kwa ntchito zovuta zamadzi. Nthawi yomweyo, mawonekedwe ogwiritsidwanso ntchito a chitoliro choyandama amachepetsa ndalama zonse zogwirira ntchito.
