Pipeline Valve chiahnak konglam hna i a biapi bikmi hna

I. Chiah hlan timhtuahnak

1. Valve sining model, hneknak tlukruannak, le luannak lei hngalh khawhnak kha suaisam ningcang he aa tlak maw tlak lo ti hngalh khawhnak ding caah zohfel.

2. Valve pum khur thianhlimnak zoh law thilri chiahnak huhphenhnak thilri le thil dang pawl kha hloh hna.

3. Butt welding pehtlaihnak valve pawl cu a hlankan in sermi a si a hau, cun flange pehtlaihnak valve pawl nih a kharnak cunglei a tthatnak kha an zoh a hau.

II. Chiahnak Lamhruainak Uknak

1. Vawlei cung valve lea dirmi cawi check valvevalve pum cung i thal nih a langhtermi lei ah fek tein chiah a hau.

2. Phunglam ah,a kai lomi stem valve, ti phun butterfly valve, le ball valve pawl cu kaphnih in chiah khawh an si, asinain hman fawinak ah ralrin a hau.

3. Electric / thli valve pawl nih actuator riantuannak le zohkhenhnak caah hmunhma an chiah a hau.

III. Welding chiahnak konglam

1. Butt welding valve cu welding tuah lio ah a cheuchum in on peng ding a si, cu nih cun lumnak thlennak ruangah a chuakmi khamnak kha a kham lai.

2. A hrampi sernak ah argon arc welding hmang law, a karlak lumnak kha valve lumnak tuakmi nak tam lo dingin uk.

3. Welding tuah hnu ah, valve cu a ttha tein aa on le a khar khawhnak hnga riantuan ning hneksaknak tuah a hau.

IV. Flange pehtlaihnak ah a biapi bikmi hmun hna

1. Flange kharnak cunglei hna cu aa tluk tein an um, cun a tam bik cohlan khawhmi thlennak cu flange lenglei diameter 0.15% nak tam a si lo.

2. Gasket cu a laifang ah chiah ding a si, bolt pawl cu aa tluk tein le tlukruang tein hren ding a si, cun rated torque cu voithum tiang phanh ding a si.

3. A lum tukmi valve pawl i pehtlaihnak hri pawl cu a linmi dirhmun ah voihnih hren a hau.

V. Quality Control

1. Install tuah hnu ah thazaang hneksaknak le kharnak hneksaknak tuah a hau.

2. System kha thianh tikah, uknak valve, flow meter le thilri dangdang hna kha hrial ding a si.

3. Valve dirhmun nambar, hneksaknak thazaang, riantuannak thazaang, tbk., a biapimi data telh in chiahnak cazin kha tling tein khumh.

Bialehnak: Valve cu pipeline caah dirkamhnak hmun ah hman ding a si lo. Valve ngan deuh pawl nih a dang tein dirkamhnak frame an herh. Install tuah hnu ah, valve cu a khar dihmi dirhmun ah a um awk a si i cross-operation rawhralnak hrial khawhnak ding caah kilven a si awk a si.
