SSAW Pipe API Spec 5L (PSL2) ee Dhuumaha Gaaska Dabiiciga ah
Markay tahay Cangzhou Spiral Steel Pipes Group Co., Ltd., aad ayaan ugu hanweynahay inaanu soo bandhigno horumarkeenii ugu dambeeyay ee warshadaha dhuumaha birta -Dhuumaha SSAW.Alaabta cusubi waxay isku daraysaa tignoolajiyada casriga ah oo leh khibrad aan la qiyaasi karin si ay u bixiso xalal aan kala go 'lahayn ee codsiyada kala duwan.
Dhuumaha SSAW waa adhuumaha alxanka lehoo laga sameeyay gariiradaha birta ah oo tayo sare leh.Waxaan isticmaalnaa tignoolajiyada sare ee extrusion si aan u hubinno heerkulka joogtada ah inta lagu guda jiro habka wax soo saarka oo dhan, ka dibna si toos ah u samee alxanka laba-geesoodka ah ee laba-geesoodka ah ee arc.Tignoolajiyadan taxaddar leh waxay dammaanad qaadaysaa isku xidhnaan adag oo waara, taasoo keenta tuubo adag oo la isku halayn karo.

Mid ka mid ah faa'iidooyinka ugu muhiimsan eetuubbo alxan leh oo wareegsanwaa xooggeeda sare, taas oo ka badan tan tuubada toosan ee alxanka leh.Tani waxay ka dhigaysaa mid ku habboon mashaariicda u baahan hufnaanta qaabdhismeedka la xoojiyay.Intaa waxaa dheer, iyada oo ay ugu wacan tahay habka wax-soo-saarka gaarka ah, tuubooyinka welded ee wareegsan ayaa la soo saari karaa iyada oo la adeegsanayo biraha birta ah ee dhuuban, taas oo u oggolaanaysa soo saarista tuubooyinka dhexroorka weyn.Intaa waxaa dheer, annagoo ka faa'iidaysanayna meelo bannaan oo balac isku mid ah, waxaan si dadaal la'aan ah u soo saari karnaa tuubooyinka dhexroorka kala duwan, iyadoo aan sii ballaarin karno wax-soo-saarkooda.
Iyada oo ay ka go'an tahay tayada adag, shirkadeena waxa ay gelisay ilo wax ku ool ah samaynta tas-hiilaadka wax soo saarka ee casriga ah.Shirkaddu waxay dabooshaa dhul dhan 350,000 mitir oo laba jibbaaran waxayna leedahay hanti dhan 680 milyan yuan.Laakiin waxa run ahaantii naga soocaya waa kooxdayada heeganka ah.Xoog-shaqaheenna oo ka kooban 680 xirfadlayaal xirfad sare leh ayaa ah xoogga ka dambeeya guushayada.
Waxaan ku hanweynahay awoodda wax-soo-saarka sannadlaha ah ee 400,000 tan oo tuubooyinka birta ah ee wareegyada ah, oo ka sarreeya heerarka warshadaha.Wax-soo-saarkan aan la barbar-dhigin wuxuu abuuray wax-soo-saarka aadka u sarreeya ee 1.8 bilyan yuan.Kooxdayada dadaalka badan waxay hubisaa in qalab kasta oo ka baxa xarunteena ay u hoggaansamaan tallaabooyinka xakamaynta tayada ugu adag, iyaga oo dammaanad qaadaya macaamiisheena tayada sare leh.
Marka la soo koobo, tuubooyinka lingaxan ee arc alxanka leh ayaa ah kuwa wax ka beddela warshadaha tuubooyinka birta.Iyada oo leh awood sare, kala duwanaansho gaar ah iyo isku halaynta aan la qiyaasi karin, waa xalka ugu dambeeya ee dhammaan shuruudaha tuubooyinka alxanka.La shaqee Cangzhou Spiral Steel Pipes Group Co., Ltd. maanta si aad khibrad ugu yeelatid mustaqbalka warshadaha birta birta.
