High-frequency welding yog siv cov nyhuv ntawm daim tawv nqaij los ua kom lub zog muaj zog tam sim no concentrated nyob rau saum npoo ntawm lub workpiece;Cov nyhuv sib thooj yog siv los tswj txoj hauj lwm thiab ntau yam ntawm txoj kev muaj zog tam sim no.Qhov ceev ntawm qhov tam sim no yog ceev heev, nws tuaj yeem ua kom sov ntawm ntug ntawm cov phaj hlau uas nyob ib sab hauv lub sijhawm luv luv, yaj, thiab paub txog cov docking los ntawm extrusion txhua tus muaj nws tus kheej zoo, tab sis kuj muaj nws tus kheej shortcomings.Nws yog feem ntau tsim nyog los tshuaj xyuas cov kev xaiv tshwj xeeb raws li cov xwm txheej tshwj xeeb.
Cov txheej txheem ntawm kev tsim hluav taws xob Resistance Vuam (ERW) Pipe yog raws li nram no:
Qhib phaj sojntsuam → Straightening milling → txiav txoj kev → Butt welding txiav → Visual tshuaj ntsuam → Ultrasonic tshuaj ntsuam → X-ray tshuaj ntsuam → Pressure test → Flat chamfering → Kev tshuaj xyuas zaum kawg
Pleev yeeb nkab lossis Dub / Varnish txheej ( customized);
nyob rau hauv bundles los yog nyob rau hauv xoob;
Ob qhov xaus nrog qhov kawg tiv thaiv;
Plain kawg, bevel kawg (2 "thiab saum toj no nrog bevel xaus, degree: 30 ~ 35 °), threaded thiab coupling;
Kos npe.
