Pipe Dhiciska Steel Carbon La Isaga Yeelaha Dheer

Qar qalbi ah oo ku jirin dhammaan waxbarashada sameynta, ku yidhi markii ugu badan la xiriira in la mid ah ee dibadda, carruurta iyo afasameedka ah ee dhexeeya karaamada ee loo yaqaan tahay dhammaan hantiwista ee kale. U soo bandhigiyey qar-qar joogga ah ee 0.12–0.30% qar (marka ah ASTM A106 Grade B, GB/T 8163 20#), waxaa ka mid ah iyaga si carruurta ay ku jirin 248–415 MPa iyo carruurta carruursiina ay ku jirin 415–620 MPa, ee la yeeshay inuu ugu baahan yihiin sistimaha carruurta hadda 16 MPa. Sareenka qalbiga ah ku haysta dhibaatooyinka carruurta, si aad ugu yahay macluumaadka ah ee la mid ah boqorka carruurta ah ee ku jirin magaalada feedwater, shafakada mekanikalka, iyo dhagaxda dambista ee ku jirin dhexdeeda seismic. Qofkooda ay ku jirin OD 15–600mm, tolbadda casriga 2–40mm, oo dulmada ay ku jirin 6–12 metro, oo ka mid ah inta badan ay ku saaritaan oo ku beelitaan. Dibadda carruurta ay ku jirin qar qar ah (dheerashada ah) oo ku jirin dab-dabka carruurta: galvanization carruurta ah (zinc layer 85μm ee la yeeshay inuu ugu baahan yihiin dhexdeeda), epoxy lining (300μm ee la yeeshay inuu ugu baahan yihiin dhexdeedka carruurta), iyo bitumen wrapping. Xaq ugu muuqata ay ku jirin hydrostatic testing (1.5x carruurta ah), ultrasonic testing carruurta carruursiina, iyo chemical analysis ee la yeeshay inuu ugu badan yihiin sulfur/phosphorus content ≤0.045% ee la yeeshay inuu ugu baahan yihiin weldability. Waxbarashada ay ku jirin shabakada carruurta, piping sameynta, iyo building frameworks, oo compliance ee ku jirin standarda ASME B31.1 (power piping) iyo EN 10216 1 (mechanical tubing) ee la yeeshay inuu ugu baahan yihiin global acceptability.
