Lined Pipes Inspection Process chungchang chipchiar taka sawifiahna
Jul 21, 2025
Industrial infrastructure tihchangtlun leh boruak humhalhna mamawh tihchangtlun a nih tak avangin lined pipe hi chemical, energy, tui supply leh thil dang dangah hman a ni nasa hle a, hei hi a thatna avang te, corrosion resistance leh service life rei zawk vang te a ni. Mahse, lined pipe quality hian an performance leh himna a nghawng nghal a, chuvangin scientific inspection process neih a pawimawh hle. He thuziak hian lined pipe enfiah dan chipchiar takin a tarlang dawn a, hei hian a kaihhnawih company te chu product quality an control tha zawk theih nan a pui dawn a ni.
1. A lan dan enfiah
Lined pipe enfiahnaah hian appearance inspection hi a hmasa ber a ni a, a bik takin pipe chung lamah crack, bubble, scratches, etc. ang chi chhiatna a awm leh awm loh enfiah a ni. Inspector-te chuan pipe chhung leh pawn lam chu a hrual a, taksa lama chhiatna langsar lo a awm theih nan enfiahna pui turin visual inspection emaw low-power magnifying glass emaw an hmang tlangpui. He link hi a awlsam viau nachungin, a taka hman theih loh thil chi hrang hrangte chu a paih chhuak thei a, a hnu lama enfiahna tur lungphum a phum thei bawk.
2. Dimension tehna
Lined pipe hian design mamawh a tlin theih nan dimension measurement hi thil pawimawh tak a ni. Inspection content-ah hian parameter chhungril diameter, pawn lam diameter, wall thickness leh pipe sei zawng te a tel a ni. A tlangpuiin, pipe size chu allowable tolerance range chhunga a awm theih nan vernier caliper leh ultrasonic thickness gauges ang chi hmanrua te chu tehna dik tak atan hman a ni. Size deviation a lian lutuk chuan installation harsatna a thlen thei a, performance a tichhe thei bawk a, chuvangin he link hi khauh taka control a ngai a ni.
3. Nondestructive testing tih a ni
Nondestructive testing hi lined pipe quality assessment-a core link a ni a, a bik takin ultrasonic testing, radiographic testing leh magnetic particle testing te a tel a ni. Ultrasonic testing hmangin pipe chhunga crack emaw pores emaw hmuhchhuah a ni a; radiographic testing hmangin pipe chhunga chhiatna awmte insem darh dan chiang takin a lang thei a; magnetic particle testing hi lei chung emaw, lei chung emaw, a hnaih ber-surface crack hmuhchhuahna atan a tha hle. Heng hmanrua te hian pipe rintlak leh himna tur pipe tichhe lovin a chhung lam quality kimchang takin a zirchiang thei a ni.
4. Pressure test neih dan tur
Pressure test hmangin lined pipe a pressure resistance a awm leh awm loh enfiah a ni. A tlangpuiin water pressure emaw air pressure test hmangin pipe chhung chu design pressure aiin a let 1.5-a pressure pek a ni a, hun engemaw chen chu leakage emaw deformation emaw a awm leh awm loh enfiah nan an dah thin. He link hian pressure resistance tha lo pipe te chu a taka paih chhuak thei a, hman tak takah pawh an himna a tichiang thei bawk.
5. Chemical hnathawh dan test
Thil bik atana lined pipe tan pawh chemical performance test neih a ngai a, chu chu corrosion resistance test leh high temperature resistance test te hi a ni. Use environment tak tak simulating hmang hian pipeline hian hun rei tak-stability chu industry bik mamawh a phuhruk em tih enfiah a ni.
Lined pipe enfiahna hian a lan dan atanga a hnathawh dan thlengin evaluation hrang hrang a huam vek a ni. Inspection standard khauh taka zawm chauhvin product quality a tichiang thei a, industrial application atan pawh venhimna rintlak pek theih a ni bawk.
