*V+Nb+Ti: ≤0.15
* Okuqukethwe kweManganese kunganyuswa ngo-0.05% kukho konke ukuncishiswa kwekhabhoni ngo-0.01%, kuze kufike ku-1.65%
Izidingo zezakhiwo zikamshini:
Amandla okukhiqiza: ≥360Mpa
Amandla okuqina: ≥460Mpa
Weld tensile amandla of ashiselwe steel pipe: ≥460Mpa
Ubude: ≥1940* AXC0.2/4600.9 , lapho i-AXC iyindawo ephambanayo yesampula eqinile
Ukubekezelela ububanzi bangaphandle kwepayipi lensimbi:
| Ububanzi bangaphandle D mm | Qeda ukuchezuka kobubanzi obungaphandle mm | |
| Ipayipi lensimbi elingenamthungo | Ipayipi lensimbi elishiselwe | |
| <60.3 | -0.8, +0.4 | |
| 60.3 D noma ngaphansi kuka-168.3 noma ngaphansi | -0.4, +1.6 | |
| 168.3 < D≤610 | ±0.005D, kodwa ubuningi ±1.6 | |
| 610 < D≤1422 | +/ - 2.0 | +/ - 1.6 |
| > 1422 | Ngesivumelwano | |
Udonga ukujiya ukubekezelelana of insimbi ipayipi:
| Ubukhulu bodonga t mm | Ukubekezela mm |
| Ipayipi lensimbi elingenamthungo | |
| 4.0 noma ngaphansi | +0.6, -0.5 |
| 4 <t <25 | +0.150t, -0.125t |
| 25 noma ngaphezulu | +3.7 noma +0.1t, noma yikuphi okukhulu -3.0 noma -0.1t, thatha okukhulu |
| Ishubhu elishiselwe | |
| 5.0 noma ngaphansi | +/ - 0.5 | |
| 5.0 | <t <15 | Hlanganisa noma susa 0.1 t |
| 15 | noma ngaphezulu | +/ - 1.5 |
Insimbi ibanga: L360N or X52N(PSL2)
Amakhemikhali ukwakheka izidingo:
C: ≤0.24
Isimo: ≤0.45
UMn: ≤1.40
P: ≤0.025
S: ≤0.015
V: ≤0.10
Nb:≤0.05
Ithi: ≤0.04
Cu: ≤0.50
Inani: ≤0.30
Cr: ≤0.30
Mo: ≤0.15
I-V+Nb+Ti: ≤0.15
* Okuqukethwe kweManganese kunganyuswa ngo-0.05% kukho konke ukuncishiswa kwekhabhoni ngo-0.01%, kuze kufike ku-1.65%.
* Akukho ukwengeza ngamabomu kwe-boron kuvunyelwe, okusele okungu-B≤0.001%
Ikhabhoni kulingana:
CEP cm: ≤0.25
I-CEIIW: ≤0.43
* Sebenzisa i-CE lapho okuqukethwe kwekhabhoni kungaphezu kuka-0.12%, futhi usebenzise i-CE IIW whenP cm okuqukethwe kwekhabhoni kungaphansi noma kulingana no-0.12%.
CEP cm = C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B
Uma umphumela wokuhlaziywa kokuncibilika kuka-B ungaphansi kuka-0.0005%, asikho isidingo sokufaka ukuhlaziywa kwesici B ekuhlaziyeni umkhiqizo, futhi okuqukethwe B kungathathwa njengoziro esibalweni esilingana nekhabhoni CEP cm.
CEIIW =C+Mn/6 (C+Mo+V)/5+(Ni+Cu)/ 15
Omakhenikha izakhiwo izidingo:
Amandla okukhiqiza: 360-530Mpa
Amandla okuqina: 460-760Mpa
Isilinganiso sesivuno: ≤0.93 (sisebenza kuphela ku-D > 323.9mm ipayipi lensimbi)
Weld tensile amandla of ashiselwe steel pipe: ≥460Mpa
Ubude obuncane: = 1940* AXC0.2/4600.9 , lapho i-AXC iyindawo ephambanayo yesampula ye-tensile.
