API 5L Grade B Carbon Steel Pipe Line Pipe

I-API 5L yeBanga B Ipayipi Lepayipi Lensimbi Lekhabhoni Elifakiwe Isithombe

Incazelo emfushane:

Ipayipi lensimbi le-API 5L yeBanga B liyipayipi lebanga elivamile lokuthuthwa kwamapayipi kawoyela negesi.Yaziwa nangokuthi yipayipi L245, okubhekiselwa kuyo ku-ISO 3183, eqanjwe ngezinga elincane lamandla okukhiqiza angama-245 Mpa (355,000 Psi).

Impahla efanayo ye-ASTM A106 B noma i-ASTM A53 B enenani elifanayo ekwakhekeni kwamakhemikhali, izakhiwo zemishini kanye nokusetshenziswa.

I-API 5L B ihlanganisa i-PSL1, i-PSL2, isevisi emuncu yamapayipi asogwini nasogwini.Izinhlobo zokwenziwa zihlanganisa ezingenamthungo futhi ezishiselwe.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Isingeniso Somkhiqizo

I-PSL1, PSL2 kanye nezinhlobo ze-Acidic Media.

Ngokuvamile kusetshenziswa i-PSL1, elingana ne-ASTM A106 B kanye ne-A53 B.

I-PSL2 iyipayipi lebanga lokucaciswa okuphezulu elinezidingo eziqinile zamandla amakhemikhali nawomshini.I-PSL2 idinga izindlela zokuhlola ezengeziwe njengokuhlola okungalimazi, ukuhlola umthelela we-CVN, i-DWT, njll.

I-API 5L B PSL2 imelwe i-API 5L BN/Q/R/M.

I-Acidic medium: Emapayipini e-asidi njengemvelo ye-H2S, impahla yepayipi inezidingo ezijwayelekile zezinto zamakhemikhali ezifana nekhabhoni, i-phosphorus nesibabule.Inkomba ejwayelekile ye-NACE MR0175.

Isibonisi somkhiqizo

Incwadi yesijobelelo

Izinhlamvu zesijobelelo zicacisa izimo zokulethwa kwepayipi:

R: Uma iginqika.

N: normalizing rolling, normalizing ukwakha, normalizing.

Q: Ukunciphisa kanye nokunciphisa.

M: I-Thermomechanical rolling noma ukwakheka kwe-thermomechanical.

S: I-Sour medium eneshubhu ye-PSL2 ye-NS, QS, MS, isb API 5L Grade B NS, API 5L B QS.

Izinhlobo ezingenamthungo nezishiselwe (ERW, LSAW, SSAW/HSAW).

Uhlobo Lomkhiqizo

Uhlobo Olungenazihibe:kufaka phakathi amapayipi angenamthungo agingqike ashisayo angaphezu kwamayintshi angu-3, amapayipi angenamthungo agoqeke abandayo angaphansi kwamayintshi angu-3.

Uhlobo lwe-ERW Welding:I-Resistance Welding, ilungele amapayipi afinyelela kumayintshi angama-24.

Uhlobo Lwe-Straight Submerged Arc Welding:Ukushisela i-arc ehlukaniswe ngobude, ilungele amapayipi anobubanzi obungaphandle obungamayintshi angu-20 ukuya kwangu-48.I-LSAW yaziwa nangokuthi i-JCOE, okusho ukwenza izimo ezisuka kumapayipi amise okwe-J, amise okwe-C, amise okwe-O, bese kuba ngamapayipi anwetshiwe abandayo.

Uhlobo lwe-SSAW/HSAW:I-Spiral Submerged Arc Welding noma i-Spiral Saw yepayipi elifika ku-100" OD.

I-API 5L Grade B, ASTM A106 Grade B kanye ne-A53 Grade B, lezi zinto ezintathu ziyizinto ezisetshenziswa kakhulu ekwakhiweni kwamapayipi noma izimboni zikawoyela negesi kanye nezokuthutha uketshezi.

I-ASTM 106 ipayipi isho ipayipi lensimbi eligoqiwe elishisayo noma elidonswe kubanda (eligoqiwe).

Ipayipi le-ASTM A53 lihlanganisa amapayipi ensimbi ashiselwe futhi angenamthungo we-carbon black material, kanti kwezinye izimo ama-hot-dip galvanized (galvanized).
