2019 China New Design Factory Engenamthungo Section Alloy Steel Pipe Tube ASTM A335-P11 G3458 Heat-Resisting Gas Air Boiler Petroleum Cracking

Incazelo emfushane:

Ipayipi eliqhekeka i-petroleum iyipayipi lensimbi elingenalutho, elide, eliyindilinga elingenamthungo.Ukusetshenziswa kwepayipi lokuqhekeka kwe-petroleum: Isetshenziselwa ukuthutha uphethiloli, uphalafini, uwoyela wedizili neminye imikhiqizo kawoyela, engamelana nokugqwala nokuguga.Ipayipi lokuqhekeka kwe-petroleum (gb9948-83) iyipayipi lensimbi yezinga lokuqala elifanele ukubhoboza kwe-geological kanye nokumba izimboni.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Sincike emandleni obuchwepheshe aqinile futhi siqhubeka sakha ubuchwepheshe obuyindida ukuze sanelise isidingo se-2019 China New Design Factory Seamless Hollow Section Alloy Steel Pipe Tube ASTM A335-P11 G3458 Heat-Resisting Air Boiler Petroleum Cracking, Ifemu yethu izinikele ekunikezeni abathengi. izimpahla ezibalulekile neziqinile zekhwalithi ephezulu ngamanani anamandla, ezikhiqiza ikhasimende ngalinye laneliseka ngemikhiqizo namasevisi ethu.
Sincike emandleni obuchwepheshe aqinile futhi sihlala sidala ubuchwepheshe obuyindida ukuze sanelise isidingoIpayipi Lensimbi Elingenamthungo kanye Nepayipi Lensimbi, Sithemba ngobuqotho ukubambisana namakhasimende emhlabeni wonke, uma ungathanda ukuthola ulwazi olwengeziwe, qiniseka ukuthi usithinta ngomusa, besilokhu sibheke ngabomvu ukwakha ubuhlobo obuhle bebhizinisi nawe.

Amashubhu kabhayela anomfutho ophansi naphakathi enziwe ngezingothi noma amabhilidi aqinile anembobo ukuze akhe ishubhu le-burr, bese liyagoqwa elishisayo, eligoqekayo elibandayo noma elidayiwe ngokubanda.Ipayipi lensimbi elingenamthungo linesikhundla esibalulekile embonini yamapayipi ensimbi yaseChina.Ngokwezibalo ezingaphelele, amabhizinisi okukhiqiza amapayipi aseChina angenamthungo akhona angama-240 ngaphezulu, iyunithi yepayipi engenamthungo yensimbi engamasethi angama-250, umthamo wokukhiqiza wonyaka wamathani angaphezu kwezigidi ezi-4.5.Ngokombono we-caliber, <φ76, i-accounting ye-35%, <φ159-650, ibalwa ku-25%.Ngokuya ngezinhlobonhlobo, amathani ayizigidi ezingu-1.9 zamashubhu ahloswe ngokujwayelekile, alinganiselwa ku-54%;amathani angu-760,000 amashubhu e-petroleum, alinganiselwa ku-5.7%;amathani angu-150,000 ezinsika ze-hydraulic, amashubhu okunemba, okubalelwa ku-4.3%;amashubhu angenalutho, amashubhu athwalayo, amashubhu ezimoto ingqikithi yamathani angama-50,000, okubalelwa ku-1.4%.

Izici zemishini yeshubhu le-boiler enengcindezi ephansi namaphakathi: amandla aqinile σb (MPa): ≥ 410 (42) amandla esivuno σs (MPa): ≥ 245 (25) ubude δ5 (%): ≥ 25 isigaba sokushwabana ψ (%): ≥ 5 , ubulukhuni: hhayi ukwelashwa kokushisa, ≤ 156HB, usayizi wesampula: usayizi wesampula 25mm ukucaciswa kokwelashwa kokushisa kanye nenhlangano ye-metallographic: imininingwane yokwelashwa kokushisa: okujwayelekile, 910 ℃, Ukupholisa komoya.Inhlangano ye-Metallographic: ferrite + pearlite.

Izinga lokukhishwa kweshubhu le-boiler elinengcindezi emaphakathi nephansi: Ishubhu yensimbi engenamthungo engu-GB3087-1999 kubhayela wengcindezi ephansi naphakathi.

Amashubhu kabhayela anomfutho ophakathi nendawo namashubhu ashisayo agoqekayo futhi abandayo adonswe (agoqiwe) angenamthungo ensimbi yekhwalithi ephezulu ye-carbon structural asetshenziselwa ukwenza amashubhu esitimu esishisa kakhulu, amashubhu amanzi agingqikayo namashubhu esimusi esishisa kakhulu samabhoyela esitimela, amashubhu amakhulu entuthu, amashubhu amancane entuthu kanye ne-arch. izitini zezitini zezakhiwo ezihlukahlukene zama-boilers aphansi naphakathi.Ikakhulukazi isetshenziselwa ama-boilers ezimboni kanye nama-boilers aphilayo ukuthutha amapayipi amanzi anomfutho ophansi naphakathi.Izinto ezimele ziyi-10 ne-20 gauge steel.

1.Kungani usikhetha ?

Inkampani yethu isineminyaka eyi-12 iku-Alibaba.com.Silawula ikhwalithi yemikhiqizo ngokuqinile, kunabantu abakhethekile bekhwalithi.

Uma uthole intengo ephansi komunye umphakeli, sizobuyisela kabili kumakhasimende mayelana nenani eliphakeme.

2.Singakanani isikhathi sakho sokulethwa?

Ngokwenani.Ngokuvamile phakathi kwezinsuku ezingu-2-7 uma lisesitokweni.Futhi izinsuku eziyi-15-20 uma zingekho esitokweni.

3.Ithini imigomo yakho yokukhokha?

A: Nge-T/T 30% kusengaphambili, kanye no-70% ngaphambi kokulethwa.

B:100% L/C lapho ubona.

C:Nge-T/T 30% kusengaphambili, kanye no-70% L/C lapho ubona.

4.Ingabe uyawahlinzeka ngamasampula?Ingabe kumahhala?

Yebo, sinikeza isampula mahhala kodwa asizikhokheli izindleko zempahla.

5.Kuthiwani uma ikhasimende linganelisekile?

Uma kunenkinga ngomkhiqizo, sithatha isibopho esigcwele.

Uma kunenkinga ohlelweni lwezokuthutha, sizokusiza ukuyixazulula.
