Esiane ahoɔden a ɛkorɔn, nhyɛso a ɛko tia, ne welding ahorow a eye kyɛn so nti, wɔde dade afiri a ɛyɛ nkuruwankuruwa a ɛyɛ nkuruwankuruwa di dwuma kɛse wɔ ngo, mframa, nsu a wɔkora so, ne adansi adwumayɛbea ahorow mu. Nanso, sɛnea ɛbɛyɛ na wɔde ne adwumayɛ mu mfaso horow adi dwuma koraa no, akwan a ɛfata a wɔfa so de di dwuma no ho hia kɛse. Nea edidi so yi de spiral steel pipe a wɔde di dwuma ho afotu titiriw ba fi afã horow a ɛfa sɛnea wɔde si, siesie, welding, ne nsɛe ho banbɔ ho.
1. Installation tips: hwɛ a wɔbɛhwɛ sɛ ɛyɛ den na ɛne ne ho hyia .
Sɛ wode spiral steel pipe rehyɛ mu a, di kan hwɛ sɛ paipu no ho nkyerɛkyerɛmu no ne project design no hyia na hwɛ paip no nipadua no mu hwɛ sɛ nneɛma a ɛde ba anaa nea wɔde sie no asɛe anaa. Ansa na wode bɛhyɛ mu no, hohoro paipu no ano na yi burrs ne welding slag no na amma joint sealing a asɛe no ankɔ so. Sɛ butt-jointing, hwɛ hu sɛ paipu axes no hyia na akwati forced splicing a ɛde stress concentration ba. Wɔ kɛseɛ-diameter spiral steel pipe ho no, wɔkamfo kyerɛ sɛ fa butt-joint adwinnadeɛ di dwuma de boa wɔ instɔlehyɛn mu, hwɛ sɛ n’awieɛ no yɛ pɛ na ɛtew welding nsɛnnennen so. Bio nso, ɛsɛ sɛ wɔde mmeae a wɔde mmoa ma no si baabi a ɛfata na wɔasiw benkum anaa nsakrae a ɛboro so esiane paipu no mu duru anaa tumi a ɛwɔ akyi nti no ano.
2. Welding Process: Nneɛma pa ne ahoɔden a wɔde di dwuma .
Spiral steel pipe connections no taa yɛ weld, na weld quality no nya pipe a ɛyɛ den no so nkɛntɛnso tẽẽ. Ansa na welding no, ɛsɛ sɛ wɔyɛ paipu no awiei no bevel na ama wɔatumi akɔ mu pɛpɛɛpɛ. Ɛsɛ sɛ wɔpaw welding nneɛma a ɛfata (te sɛ nea ɛba fam-hydrogen electrodes) ne process parameters (te sɛ current ne voltage), na ɛsɛ sɛ wɔhwɛ interpass temperatures so denneennen na amma ɔhyew no anpaapae. Sɛ worebɔ layers pii a, yi slag layer by layer no na woakwati slag inclusions ne porosity. Wɔ welding akyi no, non{5}}ɔsase sɔhwɛ (te sɛ x-ray anaa ultrasonic sɔhwɛ) na ɛho hia na ama wɔahwɛ ahu sɛ welds no nni sintɔ biara.
3. Anti-Nneɛma a wɔde twitwa nneɛma mu: ɔsom nkwa nna a wɔtrɛw mu .
Spiral steel pipes no yɛ mmerɛw sɛ rusting bere a wɔde wɔn ho hyɛ mmeae a ɛhɔ yɛ nwini na ɛyɛ mmerɛw no bere tenten, na ɛma anti{0}}corrosion treatment ho hia. Akwan a wɔtaa fa so ko tia-nkitahodi akwan no bi ne epoxy fango tar a wɔde kata so, 3PE anti-nkitahodi a wɔde kata so, anaasɛ galvanizing. Ansa na wɔde besisi hɔ no, ɛsɛ sɛ wɔyɛ paipu no nipadua no ho adwuma (te sɛ sandblasting) na ama wɔatumi akata so abata ho. Nsu nhama a wɔasie no hwehwɛ sɛ wɔbɔ ho ban wɔ cathodic ho na amma anyinam ahoɔden ankora so. Bio nso, nhwehwɛmu a wɔyɛ no daa wɔ anti-corrosion coating no ho sɛ ɛbɛsɛe na wɔasiesie no ntɛm no betumi atrɛw dade paipu no som nkwa mu kɛse.
4. Nsiesiei a wɔyɛ no daa: ɔhaw ahorow a ebetumi aba a wobesiw ano .
Bere a wɔreyɛ adwuma no, ɛsɛ sɛ wɔhwɛ paipu no mmoa nhyehyɛe no mu daa sɛ ebia ɛyɛ den sɛnea ɛbɛyɛ a ebetumi asiw deformation no ano esiane tumi a ɛwɔ hɔ anaa abɔnten so tumi nti. Wɔ nsuo afiri a ɛde nsɛm a ɛyɛ corrosive media kɔ no ho no, ɛsɛ sɛ wɔhwɛ ɔfasuo a ɛwɔ mu no so na sɛ ɛho hia a, ɛsɛ sɛ wɔsesa nsuo afiri no fasuo no anaasɛ ɛyɛ den. Wɔ awɔw bere mu no, wɔ ɔhyew a ɛba fam mu no, nneɛma a wɔde siw nsu ano no ho hia na amma dade paipu no ampaapae esiane shrinkage nti.
Saa spiral steel pipe usage techniques yi a wobɛma ayɛ yiye no remma adwuma no ahobammɔ atu mpɔn nko na mmom ɛbɛtew nsiesie ho ka so yiye, na ama wɔahwɛ ahu sɛ-bere a ɛyɛ den no adwumayɛ a ɛyɛ den a ɛwɔ pipeline nhyehyɛe no mu.
