Bonnet Yopangidwa Ndi Carbon Steel Gate Valve

Boneti yolemera ya carbon steel pachipata cha valve yopangidwa ndi ASTM A105 / ASTM A350 LF2. Zopangidwira Class 300 yothamanga kwambiri ndi mapaipi a Class 600. Mapangidwe a bonnet okhala ndi malo osindikizira olondola opangidwa ndi makina. Zolemba mwamakonda zovomerezeka.

Kufotokozera Kwathunthu: Boneti ya valve pachipata ndi gawo lofunikira kwambiri losunga kupanikizika lomwe liyenera kupirira kupsinjika kwa mzere wonse ndi kupsinjika kwa cyclic matenthedwe. Maboneti athu opangidwa ndi chitsulo cha kaboni amapangidwa pogwiritsa ntchito ukadaulo wokhotakhota wotsekedwa kuti akwaniritse kayendedwe kabwino ka tirigu, ndikuchotsa chiwopsezo cha porosity chomwe chimapezeka m'njira zina zopangira zoponya.

Bonati iliyonse imapangidwa kuchokera ku ma billets a ASTM A105 a premium kapena ASTM A350 LF2 (otsika pang'ono), okhazikika komanso osakhazikika pazofunikira za ASTM A788. Makina a CNC amawonetsetsa kukhazikika kwa nkhope ya flange (≤ 0.05 mm), kukhala ndi concentricity, ndi kulondola kwa ulusi pamalo onyamula tsinde.

Mapangidwe a bonnet opangidwa ndi bolts amakhala ndi ma graphite gaskets ozungulira komanso amavomereza zida zonyamulira (PTFE, graphite, zopanda asbestosi). Zopezeka 2 "kupyolera mu 24" mavavu a zipata zokhala ndi njira zokhazikika kapena zowonjezera za khosi la bonnet.

Zofunika Kwambiri:

• Njira yopangira: Kutseka-kufa kotentha - kapangidwe kake kapamwamba, moyo wotopa kwambiri
• Zida: ASTM A105 (muyezo) / ASTM A350 LF2 (ntchito yotsika kutentha -46°C)
• Chithandizo cha kutentha: Normalized + tempered (N + T) pa zofunikira za ASTM A105
• Machining: Full CNC - nkhope ya flange, yoboola, ulusi, chipinda chonyamula
• NDE: UT (akupanga kuyezetsa) pa forgings onse ovuta; MT (magnetic particle) popempha
• NACE MR0175 yovomerezeka yowongolera kuuma yomwe ikupezeka pautumiki wowawasa
• Dimensional muyezo: ASME B16.34, API 600

Zofotokozera:

Makampani Ogwiritsa Ntchito:

• Mafuta ndi gasi kumtunda / pakati / kutsika
• Zomera zoyeretsera ndi petrochemical
• Kupanga mphamvu (mavavu a nthunzi)
• LNG ndi cryogenic pipeline (A350 LF2)
• Zida za m'nyanja ndi m'mphepete mwa nyanja

Chifukwa Chomwe Tisankhire: Makina athu osindikizira otsekedwa (mpaka matani 2,500) ndi malo ogulitsira makina a CNC ophatikizika amatipatsa mwayi wopereka mabonati omaliza, okonzeka kusonkhanitsa mavavu kuchokera kugwero limodzi. Zolemba zonse zovuta zimaphatikizidwa ndi malipoti oyesa zinthu (MTR / CMTR) ndi malipoti owunikira. Timavomereza kuyang'aniridwa ndi gulu lachitatu ndipo tikhoza kugwirizanitsa kuyesa kwa umboni pafakitale yathu.
