Stainless steel polished pipe hian corrosion resistance tha tak a nei a, heat resistance a nei tha a, temperature strength leh mechanical property a nei tha hle a, hot workability tha tak tak stamping leh bending te a nei bawk.
Tuipui tui hmanrua, chemistry, dye, papermaking, oxalic acid, fertilizer leh thil siam chhuahna hmanrua dangah te hman a ni nasa hle. Mahse, buaina chu engtin nge polished stainless steel pipe a black surface chu a hmachhawn ang tih a ni. Hnuai, Hangao Tech (Seko machinery) chuan stainless steel pipe chunglam polished leh a enkawlna hmanrua te chu a blackening chhan thenkhat a sort out a:
A tlangpuiin stainless steel polished pipe product tha tak tak te hian hetiang dinhmun hi an nei dawn lo. Hun rei tak hman laiin tube chunglam chu a dum anga a lan chuan stainless steel polished tube hian boruak action hnuaiah oxide film a siam vang a ni. Oxide film hian stainless steel chhunga metal awm chu a oxidized loh nan a veng a ni. He oxide film hi a bik taka oxidized a ngai lo. Wipe off la, tube ah chhiatna a awm lo. Stainless steel polished tubes of different materials hian element content-ah danglamna engemaw zat an nei a, chuvangin oxidized film rawng pawh a danglam dawn a, mahse an vai hian tube-ah nghawng an nei lo. Hei hi a mawi lo nia i hriat chuan polishing pawh i ti thei ang.
Welding hnua polished stainless steel pipe chunglam chu a dum a nih chuan, hei hi welding gas thianghlim lo emaw, temperature sang tak oxidation emaw avanga lo awm a ni. A hnuaia kawng pathumte hian chutiang thil chu a thlen loh nan a zirtir che a ni.
1. Stainless steel polished tubes welding-a hman thin argon thianghlimna chu argon thianghlim takah tihpun rawh. Tube pawn lam atang chuan argon welding pangngai aiin argon thianghlim chu a eng zawk hle.
2. Backside chu argon gas hmanga ven tur a ni. Stainless steel polished pipe pawimawh tak chu welding zawhah backside protected a ni tur a ni. Chutiang a nih loh chuan high temperature oxidation chuan welding layer chu backside kal tlangin a kal tlang ang a, oxidize leh defect a siam thei ang. Backside weld polishing chu slag ang mai a ni. Protection hnuah chuan back oxidation a veng thei a ni.
3. Back protection agent chu a hnung lamah i hnawih thei a, chu chuan argon venna a humhim thei a ni. Thickness 1 mm vel hmang mai rawh. Tichuan hmalam chu solder a nih chuan a hnung lamah film te tak te a lo awm a, chu chuan protective layer a siam a ni.
4. Steel pipe-ah bright solution treatment tih tur a ni. Kan online bright solution annealing furnace hi online hmangin preheating awm lovin kan hmang thei a. Heating temperature ruat lawk chu a bul tan hnu second 10-15 hnuah a thleng thei a, hei hian energy hmanna nasa takin a humhim thei a ni. Water-cooled tunnel fully entclosed hman a ni a, chu pipe chu protective gas boruak hnuaiah a lum a, chu chuan pipe lum chu boruak chhunga oxygen awm nen a oxidize loh nan a veng a ni.
5. Stainless steel polished pipe weld marks te chu a dum tih i hmuh chuan pickling passivation paste hmangin a tifai thei ang. Acid hmangin a chung lama black oxide layer chu corrode la, chutah chuan tui thianghlim hmangin silfai rawh.
A chunga kan sawi tak te hi stainless steel polished pipe leh a enkawlna hmanrua dum surface a awm chhan a ni. I tan a ṭangkai ngei ka beisei. 100 chungchang hriat belh duh i neih chuan. Stainless Steel Industrial Welded Pipe Making Machinery , Khawngaihin min ngaihven zel ang che.
