Ungakuvimbela kanjani ukugqwala nokugqwala kumapayipi ensimbi angenamthungo angu-16Mn?

Ungakuvimbela kanjani ukugqwala nokugqwala kumapayipi ensimbi angenamthungo angu-16Mn?

I-16Mn, eyaziwa nangokuthi i-Q345, iwuhlobo lwensimbi ye-carbon engamelani nokugqwala. Ngaphandle kwendawo enhle yokugcina futhi ibekwe ngaphandle kuphela noma endaweni yemvelo emanzi nebanda, i-carbon steel izogqwala. Lokhu kudinga ukususwa kokugqwala ukuze kwenziwe kuye.

Indlela yokuqala: ukugeza nge-asidi

Ngokuvamile, izindlela ezimbili, i-organic chemistry kanye ne-electrolysis, zisetshenziselwa ukuqoqa i-asidi ukuxazulula inkinga. Ukuze kunqandwe ukugqwala kwepayipi lensimbi, i-organic chemistry pickling kuphela isetshenziselwa ukususa isikali se-oxide, ukugqwala, nezingubo ezindala. Kwesinye isikhathi, ingasetshenziswa njengesixazululo ngemuva kwe-sandblasting ukususa ukugqwala. Nakuba ukuhlanzwa kwamanzi ngamakhemikhali kungafinyelela izinga elithile lokuhlanzeka kwendawo kanye nokuba mahhadlahhadla, izintambo okusetshenzwa kulengwa kuzo azishoni futhi zingabangela kalula ukungcoliswa kwemvelo endaweni yemvelo.

2: Ukuhlanza

Ukusetshenziswa kwe-organic solvents kanye ne-solvents ukuhlanza ingaphezulu lensimbi kungasusa amafutha, amafutha emifino, uthuli, izinto zokuthambisa, kanye nezinhlanganisela eziphilayo ezifanayo. Kodwa-ke, ayikwazi ukususa ukugqwala, isikhumba se-oxide, i-welding flux, njll ebusweni bensimbi, ngakho-ke isetshenziswa kuphela njengendlela yokusiza ekukhiqizeni nasekukhiqizeni i-anti-corrosion.

4: Fafaza (spray) ukususa ukugqwala

Ukususwa kokugqwala kwesifutho (ukuphonsa) kufinyelelwa ngokusebenzisa injini kagesi enamandla amakhulu ukushayela izindwani zesifutho (zokuphonsa) ukuze zisebenze ngesivinini esikhulu, okuvumela izinto ezingagugi njengegolide, isihlabathi sensimbi, amabhola ensimbi, izingxenye zezintambo zensimbi, kanye namaminerali okufafaza (ukujikijelwa) phezu kwamapayipi ensimbi angenamthungo ngaphansi kwamandla amaphakathi. Lokhu akuqedi nje kuphela ukugqwala, ama-oxide ensimbi, kanye nemfucuza, kodwa futhi kufeza ubulukhuni obudingekayo obufanayo obuphezulu bamapayipi ensimbi angenamthungo ngaphansi komthelela oqinile nokungqubuzana kwezinto ezingagugi.

Ngemva kokufafaza (ukuphonsa) ukukhishwa kokugqwala, akukwazi nje ukwandisa umphumela wokukhangisa obonakalayo wendawo yepayipi, kodwa futhi ithuthukise umphumela wokunamathela wongqimba olulwa nokugqwala emshinini wokusebenza endaweni yepayipi.

I-Shandong Kungang Metal Technology Co., Ltd. iyibhizinisi elikhulu eliphathekayo elizinikele ekukhiqizeni nasekuthengisweni kwamapayipi ensimbi angenamthungo, amapayipi ensimbi anembayo, namapayipi ensimbi engxubevange. Imininingwane: Ububanzi bangaphandle: Φ 4mm-1200mm ukuqina kodonga: Φ 0.5mm-200mm; I-Shandong Kungang Metal Technology Co., Ltd. isebenzisa ngokugcwele inhlokodolobha yayo, umkhiqizo, kanye nezinzuzo zobungcweti ukuze ifinyelele ukukhula ngokushesha esikalini sebhizinisi. Ngemuva kweminyaka yemizamo, isisungule ubudlelwano besikhathi eside bokusebenzisana nezimboni ezinkulu zensimbi zasekhaya, okuhlanganisa i-Chengdu, i-Baosteel, i-Yegang, i-Henggang, i-Baosteel, ne-Ansteel. Sibheke ngabomvu ukuxhumana nawe!
