Thermoplastic rubber hose hi khaw lum leh khaw vawt laka invenna tha tak, inthlak danglam theihna leh chemical corrosion laka invenna tha tak a nih avangin industrial, construction, leh civil application-ah te hman a ni nasa hle. Construction quality, safety, leh service life enfiah nan construction standards kaihhnawih te khauh taka zawm a ngai a ni. He article hian thermoplastic rubber hose-a construction standard mamawh chu material thlan dan, sak dan tur buatsaih dan, installation specification, enfiah dan, leh pawm dan a\\angin systematic takin a sawifiah a ni.
Material thlan leh enfiah
1. Thil hman dan tur tehfung (Material Standards).
Thermoplastic rubber hose te hian ram pum emaw industry emaw standard kaihhnawih, GB/T 18997 "Aluminum-Plastic Composite Pressure Pipes" leh ASTM D2518 "Thermoplastic Rubber Hoses leh Hose Assemblies" te ang chi te a zawm tur a ni. Material-te chu factory certificate of conformity leh test report nen a awm tur a ni a, chutah chuan specification, model, pressure rating, leh environmental condition hman tur te chiang taka tarlan tur a ni.
2. Mit hmuh theiha enfiah
A sak hmain hose te hi mit ngeia enfiah tur a ni a, bubble, crack, dents, bawlhhlawh ang chi chhiatna a awm loh nan. Pipe wall thickness chu a inang vek tur a ni a, a rawng pawh a inmil tur a ni a, a tawp chu burr awm lovin uluk taka tan tur a ni.
3. Performance Testing neih a ni ang
A tul chuan physical performance testing atan sampling neih theih a ni a, chung zingah chuan tensile strength, elongation at break, pressure resistance, temperature resistance, leh chemical corrosion laka invenna te pawh a tel a, hei hian design mamawh zawm a nih theih nan a pui thei a ni.
In sakna atana inbuatsaihna
1. Environment mamawh
In sakna tur boruak lumna chu -10℃leh 60℃inkar a ni tur a ni. Ruah sur, vur tla, thlipui na tak, emaw, boruak lum lutuk lai pawhin hnathawh loh tur. Ambient humidity a sang chuan pipe-te a hnim loh nan leh an performance a nghawng loh nan moisture-proof measures neih tur a ni.
2. Hmanraw leh hmanrua
Hmanraw mamawh chu pipe cutter, flaring hmanrua, hot-melt machine (hot-melt connection atana tha), sealant, leh cleaning agents te a ni. Hmanraw te chu a tha em em a, pipe connection mamawh a tlin em tih enfiah rawh.
3. Personnel mamawh turte
Construction personnel te hi professional taka training nei, thermoplastic rubber pipe leh construction process te ziarang hre chiang, leh a inmil tur operating qualifications nei tur a ni a, chu chuan standardized leh safe construction process a siam thei ang.
Installation chungchang sawifiahna
1. Pipeline siam dan tur
Thermoplastic rubber pipe hi thil hrual, high-temperature heat source, emaw corrosive substance. 1. nena direct-a inhnaih loh tur a ni Pipeline Laying: Pipeline chu dinglam hawia dah tur a ni. Pipe tichhe thei tur forced bending a awm loh nan bend-ah dedicated elbows emaw large-radius bends emaw hman tur a ni.
2. Connection Methods: Pipe specification leh operating environment a zirin crimping, flaring, heat fusion, compression connection te hman theih a ni. Connection te chu a him tur a ni a, sealed tur a ni a, leak-free tur a ni. Heat fusion connection atan chuan fusion tling tak neih theih nan heating temperature leh time control a ngai a ni. Compression connection atan chuan matching compression nut leh fittings hman tur a ni a, tightening torque pawh siamtute mamawh a phuhruk tur a ni.
3. Support leh Fixing: Pipeline-ah hian support point \\ha tak tak dah tur a ni a, a rit zawng emaw pawn lam thiltihtheihna avanga deformation emaw detachment emaw a awm loh nan meter 1.5 aia hla lo tur a ni. Fixed support-te chu thil flexible (rubber pad ang chi) hmanga insulated tur a ni a, chu chuan metal support-in pipe-te chu direct-a a compress loh nan.
4. Pressure Testing: Install zawhah pressure test neih a ngai a. Test pressure hi working pressure aiin a let 1.5 a ni tur a ni a, mahse 0.6 MPa aia hniam lo tur a ni. Pressure stabilization hun chhung hi minute 30 aia tlem lo tur a ni. Leakage emaw pressure drop emaw a awm lo tih a tarlang (qualified).
Enfiah leh pawm
1. Visual Inspection: Pipe dahna chu a dinglam em tih te, connection te a secure em tih te, marking te a chiang em tih te, support te pawh a dik em tih enfiah tur a ni.
2. Functional Testing: Pressure testing bakah hian tui (or gas) flow test neih a ngai a, chu chu blockage a awm loh nan, resistance pangngai lo a awm loh nan leh system chu a normal taka a thawk tha em tih enfiah a ngai a ni.
3. Documentation: In sak zawh a nih hnuah construction record, material testing report, pressure test data, leh a kaihhnawih document dangte chu siam khawm a, project pawm theihna tur bulpui atan thehluh tur a ni.
Enkawlna leh Enkawl dan: Thermoplastic rubber pipe te hi hman laiin enfiah fo tur a ni a, a bik takin a connection te chu a lo hrual em tih leh pipe bang te chu a upa tawh em tih leh a chhe tawh em tih te ngaihven tur a ni. Hun rei tak ultraviolet light emaw chemical media-a an awm chuan an service life rei zawk nan sunshade emaw anti-corrosion coating emaw hmanga khuh ang chi venna tur ruahmanna siam tur a ni.
Thermoplastic rubber pipe siam that hian an hnathawh dan leh himna a nghawng nghal vek a ni. Pipeline system-in hun rei tak-a hnathawh dan nghet tak a neih theih nan, material thlan leh dahna tur specification atanga enfiah leh pawm thlengin construction standards khauh taka zawm a pawimawh hle. Construction unit-te chuan technical training an tihchak a, project quality tihchian nan construction standardization tihchangtlun a ngai a ni.
