Mapaipi a Spiral welded (SSAW) ama projekiti osungira madzi nthawi zambiri amakhala mipope yachitsulo yozungulira yokhala ndi mainchesi akulu, chifukwa madzi omwe amadutsa pa unit nthawi ndi yayikulu, yomwe imatha kupititsa patsogolo ntchito bwino. Popeza khoma lamkati la chitoliro cha chitsulo chozungulira chimatsukidwa ndi madzi nthawi zonse, khoma lamkati silimathandizidwa ndi anti-corrosion treatment, koma kunja kumakhala ngati mawonekedwe apamwamba, kotero kuti anti-corrosion ayenera kuchitidwa kuti athetse. kukokoloka kwa mvula komanso kukhudzidwa ndi dzuwa, kotero kuti zotchingira zotsutsana ndi dzimbiri ndizofunikira kwambiri.

Pamaso pa anticorrosion wa mipope zitsulo ozungulira ntchito kusunga madzi, pamwamba pa mipope zitsulo ayenera sandblasted, ndipo kalasi ayenera kufika st2.5. Pambuyo pa sandblasting, gwiritsani ntchito anti-corrosion primer nthawi yomweyo. Choyambirira chotsutsana ndi dzimbiri nthawi zambiri chimakhala utoto wochuluka wa epoxy zinc wokhala ndi zinc 70% kapena kupitilira apo, chapakati ndi utoto wa epoxy mica, ndipo wosanjikiza wakunja ndi anti-oxidation ndi dzimbiri. Utoto wa polyurethane.

Musanachoke ku fakitale, chitoliro chachitsulo chozungulira chimayenera kuyesedwa kuti chikhale ndi makina, flattening ndi flaring, ndipo chiyenera kukwaniritsa zofunikira za muyezo. Spiral welded zitsulo mapaipi ndi kusinthasintha kwambiri mu osiyanasiyana awiri ndi khoma makulidwe specifications, makamaka kupanga apamwamba kalasi wandiweyani mipope, makamaka ang'onoang'ono ndi sing'anga-m'mimba mwake wandiweyani mipope. Pali zofunikira zambiri pazambiri zamapaipi achitsulo ozungulira. M'mimba mwake ndi kukula kwake kwa chitoliro chachitsulo chozungulira chiyenera kuyendetsedwa mosinthasintha.

Kukhazikitsa kwa anti-corrosion engineering kuyenera kukwaniritsa izi zisanachitike:

Choyamba, ndondomeko ndi zolemba zina zaumisiri zatha, ndipo zojambula zomanga ziyenera kuwunikira pamodzi. Chachiwiri, kuwululidwa kwaukadaulo kwa mapulani omanga kumamalizidwa, ndipo kuphunzitsa kwaukadaulo wachitetezo ndi maphunziro ofunikira aukadaulo amakwaniritsidwa. Chachitatu, zida zonse, zopangira mapaipi ndi zotengera ziyenera kukhala ndi satifiketi ya fakitale, kapena satifiketi yofananira ya akaunti. Chachinayi, zida, makina, zida zomangira ndi malo ndizokwanira. Chachisanu, payenera kukhala zida zodzitetezera zodalirika zomwe zili zotetezeka komanso zodalirika, ndipo madzi omanga, magetsi, ndi gasi ziyenera kukwaniritsa zofunikira zomanga mosalekeza.
