Ukunyamezelana okungaphandle kwentsimbi yombhobho wentsimbi:
| I-Outter Diameter D mm | Ukuphela ngaphandle kobume be-Deameter MM | |
| Umbhobho wentsimbi engenamthungo | Umbhobho wentsimbi ye-weldied | |
| <60.3 | -0.8, +0.4 | |
| 60.3 d okanye ngaphantsi kwe-168.3 okanye ngaphantsi | -0.4, +1.6 | |
| 168.3 <D≤610 | ± 0.005D, kodwa iphezulu ± 1.6 | |
| I-610 <D≤1422 | + - 2.0 | + - 1.6 |
| > 1422 | Ngesivumelwano | |
Udonga ubukhulu ukunyamezelana of intsimbi umbhobho:
| Ubunzima beWall tmm | Ukunyamezelana mm |
| Umbhobho wentsimbi engenamthungo | |
| 4.0 okanye ngaphantsi | +0.6 ,0.5 |
| 4 <t <25 | + 0.150t ,0.1255t |
| I-25 okanye ngaphezulu | +3.7 OKANYE XHO96 |
| Ityhubhu ye-weldied | |
| 5.0 okanye ngaphantsi | + / - 0.5 | |
| 5.0 | <t <15 | Dibanisa okanye thabatha 0.1 t |
| 15 | okanye ngaphezulu | + - 1.5 |
Intsimbi Ibanga: L360N or XI-52n(I-PSL2)
Ikhemikhali ukwakhiwa Iimfuno:
C: ¶0.24
Si: ≤0.45
Mn: ≤1.40
P: ¶0.025
S: ≤0.015
V: ≤0.10
QAPHELA:≤0.05
I-TI: ≤0.04
Cu: ≤0.50
Ni: ≤0.30
CR: ≤0.30
Mo: ≤0.15
V + NB + TI: ≤0.15
* Umxholo we-manganese unokunyuswa nge-0.05% ye-0.01% ye-0.01% kumxholo wekhabhoni, ukuya kuthi ga kwi-1.65%.
* Akukho mdibaniso ye-boron ovunyelwe, intsalela ye-B≤0.001%
Ikhabhoni ngokulinganayo:
I-CGE CM: ≤0.25
Ceiiiw: ≤0.43
* Sebenzisa i-CE xa umxholo we-carbon ungaphezulu kwe-0.12%, kwaye usebenzise i-CE IP ye-cm i-cm i-cmbon iphantsi okanye ilingane ne-0.12%.
I-CEB = C + i-I / 30 + mn / 20 + i-cu / 20 + i-NI / 20 + i-7 + i-40 + i-7 + 10 + 10b
Ukuba iziphumo zohlalutyo lwe-smpling lwe-B lingaphantsi kwe-0.00055%, ke akukho sidingo sokubandakanya uhlalutyo lwezinto ezikwimveliso ye-CAPbon elinganayo.
Ceiiiw = c + mn / 6 (C + Mo + V) / 5 + (Ni + cu) / 15
Umatshini iipropathi Iimfuno:
Isivuno: I-360-330MPA
Amandla amanqindi: 460-760mpa
Umyinge we-Yave: ≤0.93 (isebenza kuphela kwi-D> 323.9mmm yentsimbi yombhobho)
Amandla e-Wold ye-Wood DedDed Pipe: ≥460mpa
Ubuncinci be-Elongition: = 1940 * I-AXC0.2 / 4600.9, apho i-AXC yindawo yecandelo lecandelo lesampulu yentensile.
Uvavanyo lwempembelelo ye-CVN ye-tube

| Chaza ububanzi be-DMM | Ubungakanani obugcweleyo i-CVNAMANDLA AMANDLAKvj |
| I-508 okanye ngaphantsi | 27 |
| > 508 ukuya kwi-762 | 27 |
| > 762 ukuya kwi-914 | 40 |

| > 1219 ukuya kwi-1422 | 40 |
| > I-1422 ukuya kwi-2134 | 40 |
Ngaphandle ububanzi ukunyamezelana of intsimbi umbhobho:
| I-Outter Diameter D mm | Ukuphela kokuphambuka kobuncinci | |
| Umbhobho wentsimbi engenamthungo | Umbhobho wentsimbi ye-weldied | |
| <60.3 | -0.4, +0.8 | |
| 60.3 d okanye ngaphantsi kwe-168.3 okanye ngaphantsi | -0.4, +1.6 | |
| 168.3 <d = 610 | ± 0.005D, kodwa iphezulu ± 1.6 | |
| I-610 <d = 1422 | + - 2.0 | + - 1.6 |
| > 1422 | Ngesivumelwano | |
Udonga ubukhulu ukunyamezelana of intsimbi umbhobho:
| Ubunzima beWall tmm | Ukuqiqa |
| Umbhobho wentsimbi engenamthungo | |
| 4.0 okanye ngaphantsi | +0.6 ,0.5 |
| 4 <t <25 | + 0.150t ,0.1255t |
| I-25 okanye ngaphezulu | +3.7 okanye + 0.1T, nayiphi na enkulu -3.0 okanye -0.10, thabatha ezinkulu |
| Umbhobho we-weldied | |
