Overview
Nemweya wedu wekuvimbika manejimendi,kubatana, mabhenefiti uye kufambira mberi, tichavaka ramangwana rakabudirira pamwe nesangano rako rakakosha reDiscount wholesale China Carbon Steel Seamless Pipe Nace API 5L X52 X60 X65 X70 Psl2 Oiri Pipeline Gasi Pipe, Kambani yedu yakatsaurirwa kupa vatengi nepamusoro uye Zvigadzirwa zvakatsiga zvemhando yepamusoro pamutengo wehukasha, zvichiita kuti anenge mutengi wese afare nemasevhisi edu uye zvigadzirwa. Isu tine timu yakazvitsaurira uye ine hukasha yekutengesa, uye akawanda mapazi, anoitira vatengi vedu vakuru. Isu tanga tichitsvaga kwenguva refu bhizinesi kudyidzana, uye tinovimbisa vatengesi vedu kuti ivo vanozo batsirikana munguva pfupi uye kwenguva refu.
Imwe nharaunda inoshanda nesimba inoda anti acid kugona (Inowanzodikanwa kuti pombi ive ne acid corrosion resistance kana chidimbu che hydrogen sulfide chasvika 300Pa). Panzvimbo iyi, pane zvakakosha zvinodiwa kune kabhoni yemukati, sulfur yemukati, phosphorus yemukati uye kuona kukanganisa, inoda HIC (hydrogen induced kutsemuka) uye SSC (Sulfide stress cracking).
HIC bvunzo: Muenzaniso, 100+/- 1mm kureba uye 20+/- 1mm yakafara, yakaiswa mune maviri akajairwa bvunzo mhinduro: Solution A (sodium chloride uye acetic acid mhinduro yakazadzwa nehydrogen sulphide pakamuri tembiricha uye kumanikidza) uye Solution B. (synthetic yemvura yegungwa mhinduro yakazara nehydrogen sulphide pakamuri tembiricha uye kumanikidzwa) kwemaawa 96. Pane matatu test indexes: the crack senitivity ratio CSR≤2%, the crack length ratio CLR≤15%, uye crack thickness ratio CTR≤5 %.

Iine pfungwa yekukotama nzira saizi saizi 115mm * 15mm * 5mm
Pane nzira ina dzekuita izvi:
A: NACE yakajairika tensile bvunzo: yakanyanya kusingakundike kusagadzikana mukati me720 maawa
B: NACE yakajairika yekubhenda bvunzo: yakanyanya kusingakundike kusagadzikana mukati meawa 720
C: NACE yakajairwa C mhete bvunzo: yakanyanya kusingakundike kusagadzikana mukati me720 maawa
D: NACE yakajairwa kaviri cantilever beam (DSB) bvunzo: Avhareji yeKISSC (SSC chikumbaridzo chekusimbisa coefficient) cheiyo yakadzokororwa bvunzo sampuli yechokwadi bvunzo.

Test Chinodiwa
Hydrostatic test
Pipe yekumira kuyedza hydrostatic pasina kuvuza kuburikidza nemusono we weld kana muviri wepombi. Majoini haafanire kuongororwa hydrostatic kupa zvikamu zvepombi zvakashandiswa zvakaedzwa zvakabudirira.

- Kune pombi ine D/t> 10, hapazovi nekuvhurwa kweweld isati yasvika kureba pakati pemaplateti isingasviki 30% yepakutanga dhayamita yekunze.
- Kune mamwe saizi tarisa kune yakazara API 5L yakatarwa.
CVN kukanganisa bvunzo yePSL2
Mazhinji PSL2 pombi saizi uye mamakisi zvinoda CVN. Seamless pombi inofanirwa kuongororwa mumuviri. Welded pombi inofanirwa kuyedzwa mumuviri, pombi weld uye nzvimbo yakakanganiswa nekupisa. Tarisa kune yakazara API 5L yakatarwa yechati yehukuru uye mamakisi uye inodiwa yakanyudzwa simba kukosha.
