1. Nhwehwɛmu a wɔyɛ .

Appearance inspection yɛ anammɔn a edi kan wɔ nhwehwɛmu a wɔyɛ wɔ lined pipes ho, titiriw no hwɛ sɛ ebia sintɔ te sɛ mpaapaemu, ahurututu, nsensanee, ne nea ɛkeka ho wɔ paipu no ani anaa. Nhwehwɛmufoɔ taa de aniwa mu nhwehwɛmu anaa deɛ ɛba fam-Power magnifying glasses di dwuma de boa wɔ hwɛ mu de hwɛ sɛ paipu no mu ne akyi no yɛ torotoro na honam fam ɔsɛeɛ a ɛda adi pefee biara nni mu. Ɛwom sɛ saa nkitahodi yi yɛ mmerɛw de, nanso ebetumi ayi nneɛma a ɛda adi sɛ ɛnyɛ nea ɛfata afi mu wɔ ɔkwan a etu mpɔn so na ɛto fapem ma nhwehwɛmu a edi hɔ.

2. Nsusuwii susudua .

Nsusuiɛ susudua yɛ anammɔn titire a ɛbɛma wɔahwɛ sɛ lined pipe no di nhyehyɛɛ ahwehwɛdeɛ no so. Nhwehwɛmu no mu nsɛm no bi ne parameters te sɛ mu diameter, akyi diameter, ɔfasu no mu duru ne ne tenten a paipu no. Mpɛn pii no, wɔde nnwinnade te sɛ vernier calipers ne ultrasonic thickness gauges di dwuma de susuw pɛpɛɛpɛ de hwɛ hu sɛ paipu no kɛse wɔ tolerance a wɔma ho kwan no mu.

3. Nsɔhwɛ a ɛnyɛ nea ɛsɛe ade .

Nondestructive testing yɛ core link a ɛwɔ quality assessment a ɛwɔ lined pipes mu, a nea ɛka ho ne ultrasonic testing, radiographic sɔhwɛ ne magnetic particle testing. Wɔde ultrasonic sɔhwɛ di dwuma de hwehwɛ mpaapaemu anaasɛ ntini a ɛwɔ afiri no mu; Radiographic sɔhwɛ betumi akyerɛ pefee sɛnea sintɔ ahorow a ɛwɔ paipu no mu no kyekyɛ; Magnetic particle testing fata sɛ wɔde hu asase ani anaasɛ ɛbɛn{1}}surface cracks. Saa akwan yi betumi asusuw ne mu su ho yiye a ɛrensɛe paipu no de ahwɛ ahu sɛ paipu no mu ahotoso ne ahobammɔ.

4. Nhyɛso sɔhwɛ .

Wɔde nhyɛso sɔhwɛ di dwuma de hwɛ sɛ nhyɛso a ɛko tia paipu no gyina hɔ ma.

5. Nnuruyɛ ho sɔhwɛ .

Wɔ lined pipes ho ma atirimpɔw titiriw no, nnuru adwumayɛ sɔhwɛ nso ho hia, te sɛ corrosion resistance test ne high temperature resistance test. Ɛdenam sɛnea wɔyɛ nneɛma a wɔde di dwuma ankasa no ho mfonini so no, wɔsɔ hwɛ bere tenten-bere tenten a ɛwɔ nsu afiri no mu no mu de hwɛ hu sɛ edi nnwuma pɔtee bi ahiade ho dwuma.

Nhwehwɛmu nhyehyɛe a ɛwɔ lined pipes mu no kata nhwehwɛmu ahorow a edi mũ so fi anim kosi adwumayɛ so. Ɛdenam nhwehwɛmu gyinapɛn ahorow a wobedi akyi pɛpɛɛpɛ so nkutoo na wobetumi ahwɛ ahu sɛ nneɛma no yɛ papa na wɔde ahobammɔ a wotumi de ho to so ama wɔ mfiridwuma mu dwumadie mu.
