API 5L PSL1 iyo PSL2 Farqiga u ah Dhuumaha Khadka Birta
Tuubooyinka khadka ee API 5L PSL2 way ka sarreeyaan PSL1
a. PSL waa magaca gaaban ee heerka heerka badeecada. Heerka caadiga ah ee wax soo saarka ee tuubada khadka ayaa leh PSL1 iyo PSL2, sidoo kale waxaan dhihi karnaa heerka tayada ee loo qaybiyay PSL1 iyo PSL2. PSL2 wuu ka sarreeyaa PSL1, ma aha oo kaliya heerka kormeerku wuu ka duwan yahay, sidoo kale hantida kiimikada, heerarka xoogga farsamada way ka duwan yihiin. Markaa marka la dalbado tuubada khadka API 5L, waa in si cad loogu sheegaa cabbirka, darajooyinkan qeexitaanka guud, waa in sidoo kale la caddeeyaa heerka wax soo saarka, PSL1 ama PSL2.
PSL2 aad ayuu uga adag yahay PSL1 xagga sifooyinka kiimikaad, xoogga adkaysiga, tijaabada aan burburin, iyo tijaabada saamaynta.
Hababka tijaabada saamaynta kala duwan ee PSL1 iyo PSL2
b. API 5L PSL1 dhuunta xariiqda birta looma baahna si loo sameeyo tijaabada saamaynta.
Dhuumaha birta ee API 5L PSL2, marka laga reebo Fasalka X80, dhammaan darajooyinka kale ee tuubada khadka API 5L waxay u baahdeen tijaabada saamaynta heerkulka 0℃. Celceliska qiimaha Akv: jihada dhaadheer≥41J, u leexo≥27J.
Wixii API 5L Fasalka X80 PSL2 tubbada xariiqda, at 0℃ dhammaan cabbirka, saamaynta tijaabin qiimaha celceliska Akv: jihada dhererka≥101J, jihada leexashada≥68J.
Tijaabada haydarooliga ee kala duwan ee tuubada khadka API 5L ee PSL1 iyo PSL2
c. Dhuumaha khadka API 5L PSL2 waa inay sameeyaan tijaabada hydraulic ee tuubo kasta, iyo qeexida heerka API ma oggola in la sameeyo tijaabada aan burburin ee beddelka tijaabada hydraulic, tani sidoo kale waa farqi weyn oo u dhexeeya heerka Shiinaha iyo heerka API 5L. PSL1 looma baahna Tijaabo Aan Burbursanayn, PSL2 waxa ay samaynaysaa Tijaabada Aan Burburinta ahayn ee tuubo kasta.
Halabuurka kiimikaad ee kala duwan ee tuubada khadka API 5L ee PSL1 iyo PSL2
d. Halabuurka kiimikada iyo xoogga farsamada ayaa sidoo kale ka duwan inta u dhaxaysa API 5L PSL1 tuubada khadka iyo API 5L PSL2 tuubada. Faahfaahinta faahfaahsan sida hoos ku qoran. API 5L PSL2 waxay leedahay xaddidaadyo leh kaarboonka u dhigma, halkaas oo jajabka kaarboonka ka weyn 0.12%, oo siman ama ka yar 0.12%. CEQ kala duwan ayaa lagu dabaqi doonaa. Dhuumaha khadka ee PSL2 xoogga xajinta ayaa leh xadka ugu badan.
