Science leh technology lama hmasawnna leh thil siam chhuahna kawngah eng thil pawh thawn chhuah ni se, inbel chu pumpelh theih loh a ni. Mahse, a chhe lai atanga leakage hian device hnathawh dan pangngai a nghawng mai bakah boruak a ti bawlhhlawh a, system pumpui boruak a tichhe bawk. Chuvangin, wear chhan hriatthiam leh thiam a ngai a, parameter leh design structure te chu a remchan dan anga thlan a ngai a, a parts te chu a inbel duh part te chu enfiah leh enkawl reng a ngai a, chutiang chuan device performance chu a taka hman theih a nih theih nan leh service life pawhsei theih a ni.
A hmasa berah chuan, wear-resistant ceramic pipe leh pipe pangngai inthlauhna chu a hmasa zawk chu wear-resistant layer angin wear-resistant ceramics hmanga lined a ni a, a hnuhnung zawk chu steel pipe pangngai (or thil dang) a ni.
Pahnihnaah chuan, wear-resistant ceramics leh steel pipe pangngai inkara material danglamna:
Material danglamna chu, alumina wear-resistant ceramics chu a hardness sang, wear resistance sang, impact resistance, oxidation resistance, corrosion resistance, leh temperature resistance sang leh hniam vanga hman lar ber a ni ta a ni.
A tawp berah chuan wear-resistant ceramic pipe-te ṭhatna (he thuziak-a tarlan thil pahnih caliber leh wall thickness leh hnathawh dan inang chiah chiah hmanga tehkhin):
1. Wear resistance-a hlawkna awm chhunte .
Wear-resistant ceramic pipe hian mohs hardness 9.0 a nei a, hei hi HRC90 aia tam nen a inang a, a chhan chu lining layer hi corundum ceramic (A-AL2O3) a nih vang a ni. Wear-resistant ceramic pipe-te service life chu pipe pangngai aiin a let 10-in a sang a; Powder Metallurgy Institute of Central South University-in a chhut dan chuan, wear-resistant ceramics-te wear resistance chu manganese steel aiin a let 266-in a inthlau a, high-chromium cast iron aiin a let 171.5-in a tam zawk bawk. Pipe pangngai nena khaikhin chuan wear resistance tha zawk. Wear-resistant ceramics hian hardness sang tak a nei a. Shanghai Institute of Ceramics, Chinese Academy of Sciences tehna atanga a lan dan chuan Jingcheng Special Ceramics siam corundum ceramics density hi steel aiin a chanve chauh a ni.
2. A chhung lam bang chu a smooth a, non-caking .
Pipe te chu wear-resistant ceramics hmanga lined te, a chhung lam a smooth a, a bun tam poh leh a smooth zawk a, running resistance a te a, caking a awm lo a, pipe te pawh a block lo.
3. Corrosion resistance chak tak .
Wear-resistant ceramic pipe hi a neutral a, a chhan chu lining ceramic layer hi (Al2O3) a nih vang a ni. Chuvangin, acid leh alkali resistance leh seawater corrosion resistance a nei a, anti-scaling leh ziarang dang a nei bawk.
4. Thermal stability tha tak .
Wear-resistant ceramic pipe hi corundum ceramic (AL2O3) avanga crystal structure nghet tak pakhat a ni. Chuvangin, composite pipe chu hun rei tak chhung chu a temperature range -50--500℃ah a thawk tha thei a ni. Material hian thermal stability tha tak a nei a.
5. A man tlawm .
Wear-resistant ceramic pipe hi a rit a, an density hi steel aiin a chanve chauh a ni. Wear-resistant ceramic pipe hi pipe pangngai aiin a chanve vel a rit zawk a, a man pawh a tlawm zawk.
6. In sakna awlsam tak .
Wear-resistant ceramic pipe te hian welding performance tha tak an nei a, a rit loh vang a ni. Chuvangin, welding, flange leh hmanraw dangte pawh hman theih a ni a, a sak leh dah pawh a awlsam hle.
7. Cost performance sang tak .
Energy hmanral tihtlem te, thlak tam dan tihtlem te, enterprise siam chhuah theihna tihpun te, pipeline "run, leak, leak" tihtlem te, boruak humhalh leh himna tihchangtlun te.
