Anti-corrosion steel pipe no yɛ nea wɔde di dwuma kɛse wɔ petroleum, nnuru, ne abɔde mu mframa adwumayɛbea ahorow mu. Ne nnyinasosɛm titiriw ne sɛ ebesiw nsɛe ano na atrɛw ne som nkwa mu denam akwan titiriw so. Ɔkwan a wɔfa so de di dwuma no titiriw ne anammɔn atitiriw abiɛsa: asase ani ayaresa, ade a wɔde kata so, ne nhwehwɛmu.
1. Aduru a wɔde yɛ nneɛma a ɛwɔ soro .
Anamɔn a edi kan a wode bedi dwuma wɔ anti-corrosion steel pipe no mu ne sɛ wobɛhohoro ɔfasu no ho yiye de ayi rust, oil, ne oxide layers afi hɔ. Akwan a wɔtaa fa so yɛ no bi ne anhwea a wɔde bɔ (SA2.5 anaa nea ɛboro saa) anaa nnuru a wɔde twitwa nneɛma mu na ama wɔahwɛ ahu sɛ ɔfasu no so ayɛ mmerɛw pɔtee bi na ama ade a wɔde kata so abata ho no ayɛ kɛse. Ɛsɛ sɛ wɔde anti-nkitahodi ayaresa di dwuma wɔ nnɔnhwerew 4 akyi a wɔde siw oxidation a ɛto so abien ano.
2. Nneɛma a wɔde kata so .
Akwan ahodoɔ a wɔfa so kata so no wɔ hɔ ma anti-corrosion steel pipe, a epoxy coal tar, 3PE (abiɛsa-layer polyethylene), ne FBE (fusion bonded epoxy powder) ka ho.
Epoxy Coal tar: Wɔde brush anaa spray di dwuma, ɛyɛ ntade abien: primer ne topcoat, a ne nyinaa yɛ kɛse sen 0.6mm. Ɛho hia sɛ wɔyɛ aduru wɔ baabi a ɛhɔ yɛ nwini nnɔnhwerew 24. 3PE Anticorrosion: Wɔde winding process di dwuma, fusion-Bonded epoxy powder no di kan de di dwuma (base layer), a ɛdi akyi ne adhesive ne polyethylene (a akyi layer), a ne nyinaa yɛ kɛse sen anaasɛ ɛne 2.5mm yɛ pɛ. Ɛfata ma nsu afiri a wɔasie.
FBE Anticorrosion: Epoxy powder no yɛ electrostaticly sprayed tẽẽ, melting wɔ ɔhyew a ɛkorɔn mu ma ɛyɛ dense coating. Mpɛn pii no, ne kɛse yɛ 400-1000μm, na ɛwɔ ɔhyew a ɛkorɔn a ɛko tia.
3. Nhwehwɛmu a ɛyɛ papa .
Sɛ wowie a, ɛhia sɛ wɔyɛ nhwehwɛmu a emu yɛ den, a nea ɛka ho ne nhwehwɛmu a wɔde aniwa hu (ma ahurututu ne mpaapaemu), ne kɛseɛ a wɔsusu (de hwɛ sɛ wɔdi nsusuiɛ gyinapɛn so), spark detection (de hwɛ sɛ nsuo a ɛretuo biara nni hɔ), ne adhesion sɔhwɛ. Ɛsɛ sɛ wosiesie mmeae a ɛmfata no ntɛm ara na ama wɔatumi asiw ɔporɔw no ano yiye.
AKWANKYERƐ: Hyɛ nneɛma a ɛbɔ wo ho ban bere a woreyɛ adwuma no na amma paint no ne wo were ntam ankɔ. Ɛsɛ sɛ ɔhyew a ɛwɔ baabi a ɛwɔ no yɛ digrii 5 kosi 40 , na nsu a ɛwɔ mu no nnu 85%. Adwumayɛ a ɛfata betumi ama dade nhama a ɛyɛ corrosion resistance no atu mpɔn kɛse, na ama adwuma no ayɛ nea ahobammɔ wom na atra hɔ akyɛ.
