Spiral Walded Carbon Steels pombi yemutero wemvura tubing

Spiral Walded Carbon Steels pombi yeMvura Mutsetse Tubing Inotaridza mufananidzo

Tsananguro pfupi:

Kuyambuka nzvimbo huru yezvivakwa, kushanda kwesamusha kwemasisitimu emvura uye maitiro emaindasitiri anovimba zvakanyanya nekusagadzikana uye kushanda mapepa. Pakati pemhando dzakasiyana dzemapapiro mukushandisa, spiral welded carbon masimbi mapipi anofanirwa kutarisisa kune simba ravo repamusoro uye rinoita basa. Pazasi anotanga tsananguro yekukosha uye zvakanakira zveSpiral Welded Carbon Steel Pipi mumutsara wemvura tubing uye yesimbi pombi yelding.

1. Nzwisisa Spiral Wacheed Carbon Steel Pipi:

Spiral Wacheld Carbon Steel pombiinoumbwa yakaumbwa uye yakavezwa kubva pamarairi esimbi. Iyo yakasarudzika yekugadzira maitiro inoita kuti pombi idzi dzinosimba uye dzakawanda dzakasimba, dzinokwanisa kutsungirira zvakakwirira zvemukati uye zvekunze zvinonhuhwirira. Iko kugona kuramba corrosion uye deformation kunoita kuti zviite zvakakodzera kuti zviite zvakasiyana siyana zvekushandisa, kusanganisira mapepa emvura uye pombi yesimbi yelding.

2. Mutsetse wemvura uchibika:

Mune mvura yekugovera masisitimu, iyo yakachengeteka uye inoshanda kuburitsa kwemvura yakachena ndeyekutsoropodza. Spiral welded Carbon Steel pombi yakaratidza kuve sarudzo yakavimbika yemapepa emvura nekuda kwezvinhu zvaro zvecrosion. Iyo yakatsetseka pamusoro peiyi pombi inoderedza kupokana, inoona kuyerera kwemvura nguva dzose uye kuderedza turbulence. Uyezve, simba risingaverengeki uye kusimba kwevimbiso kubva mukudziya, kupaza, uye kutadza kwakarongeka, kunoita kuti mvura ipo ipo, yakavimbika.

3. Metal pombi yelding:

Iyo indasitiri yeTalting inovimba zvakanyanya paCarral weCarbon Steel pombi yeiyo dzakasiyana siyana dzekushandisa. Simba rakasiyana-siyana uye kushanduka kwemapepa aya kunovaita ivo vakanakira pombi yelding. Kunyangwe kuvaka matangi akakura ekuchengetedza, mapipi ekutakura mafuta uye gasi, kana zvigadzirwa zvemagetsi mumasitirwo emasitiri, spiraled carbon zvibayiro zvine basa rakakosha basa. Kufanana kwamajoinhi majoini kunozivisa kuvimbika uye kuchengetedzwa kwechimiro, kuderedza kukosha kwekugara kwekugara kana kugadziriswa.

4. Kubatsira nezvakanaka:

4,1 mutengo-unoshanda Solution: Spiral Welded Carbon Steel pombi inopa mhinduro-inobudirira mhinduro yemvura uye yemvura pombi yelding. Kugara kwavo uye kurwisa kweora kunove nechokwadi chehupenyu hwebasa rekushanda kwenguva refu, nekudaro kudzora kutsiva uye mari yekugadzirisa.

4.2 Zviri nyore kuisa: Iyo Spiral Welding tekinoroji inoshandiswa mukugadzira maitiro kunogona kuburitsa nguva yakareba uye kuenderera mberi pombi, kuderedza kudiwa kwekugara uchiita majoini. Iyi dhizaini yakagadziriswa inoita kuti kuisirwa mari, kuponeswa nguva uye kushanda nesimba.

4.3 Kuwedzera Ivo vanogona kuve vakasarudzika kusangana chaizvo zviitiko zvepurojekiti, kujairana nemhando dzakasiyana-siyana dzemvura, dzvinyiriro uye tembiricha.

4.4 Zvakatipoteredza Dziviriro: Carbon Steel chinhu chinogadziriswazve chinobatsira pakutsigira kwezvakatipoteredza. Spiral welded carbon masimbi mapipi anogona kudzoserwa uye kushandiswazve, kuderedza marara uye kuchengetedza zviwanikwa zvakasikwa.

Mukupedzisa:

Kugona uye zvakanakira zveSpiral welded carbon Steel pombi mumvura pombi uyeMetal Pipe Waldinghaigone kutsamwiswa. Iko kusarudzika uye kuvimbika kutamiswa kwemvura uye nemvura yemaindasitiri inovimbisa zvakanyanya pakubata kwavo, kupokana nekuiswa kwekuisirwa. Sezvo kudikanwa kwekusimba kwakasimba uye kwakabudirira kunoshanda kwakamuka
