ASTM A672 Pipe Madang Hpe Hkrang Shapraw Ai Lam: Madang, Hpung, Jep joi ai lam, hte Laika Buk ni

Pressure piping project ni hta, ndai masat masa gaw, delivery gaw pipe galaw shapraw ai lam sha n-ga, hkum tsup ai, bai maram yu na matu-jin jin rai sai sakse package hte jep joi ai lam hpe lai di ai lam hpe law law lang madun dan ai. OD kaba, bunghku kaba, hkam sha chye ai n-gun ja ai lamu ga jarit ni, n-gun ja ai hkam la ai shara ni gaw dawdan lam lahkawng hpe galaw ya ai: quality hpe n-gun n-htum hkra bai shapraw lu na kun, hte laika buk ni hpe shawng nnan tang madun ai shaloi bai maram yu lu na kun.

Standard gaw hpa hpe hkang ai

Ndai masat da ai lam gaw, n-gun ja ai -hkum hkrang n-gun n-gun n-gun n-gun n-rawng ai aten hta, n-gun ja ai -magam bungli galaw na matu yaw shada ai, n-gun ja ai hka htung-quality plate kaw na galaw shapraw ai welded steel pipe hpe shinggrup da ai. Tatut hta, htawn tsun ai hkrang masa hku nna bungli galaw ai:

Npawt nhpang arung arai gaw ahkang jaw da ai plate masa ni hta lawm ra ai, hkan tam mai ai lam hpe jahtum kaw nna-hpang kaw nna hkan tam ra ai.
Hpaga lam hte welding galaw ai lam hpe hkang lu ai, jep joi lu ai, ka matsing da lu ai rai ra ai .
Hkamja lam hte seng nna, jep joi ai lam, chyam dinglik ai lam ni hpe mari na matu matsun ai madang hta lachyum shaleng lu ra ai.

"Welded pipe standard" hku sha galaw ai gaw, lam hpe n lu galaw ai. Shi a project manu gaw hkap la ai lam hpe galaw mai ai ra kadawn ai lam ni de lock galaw ai hta rai nga ai.

Grade system hpe gara hku hti na .

Grade ni hpe laika si langai hte nambat langai hku nna ka chye ai. Project bungli hta, tatut galaw mai dik ai lachyum gaw:

Laika hpe plate system (sh) series hpe chye na matu lang ai.
Dai nambat hpe n-gun-madang masat kumla hku lang ai .

Ndai lam a majaw grade lata ai lam gaw n-gun atsam bawngban ai lam sha n rai nga ai. Dai gaw, n-gun ja ai lamu ga jarit langai a npu hta, n-gun ja ai tsi lajang ai lam, jep joi ai lam, hkan tam lu ai lam ni hpe galaw lu na matu, arung arai npawt nhpang hpe ngang ngang jum da ya ai. Lot lapran na performance swings kaba ni gaw, welding galaw ai sha n-ga, n chye na ai arung arai hte hkap la ai lamu ga jarit ni a majaw grau law ai.

Hpa majaw class gaw hkap la na lam hpe ayan dawdan ya ai

Project hta ayan shut ai lam langai gaw, class hpe secondary detail hku nna mu mada ai sha, grade hpe atsawm sha tsun dan ai lam re. Teng sha nga yang, class gaw hkap la ai lam hpe galai shai ai hku nna galaw chye ai, grau nna TPI (sh) madu hold-point review npu hta.

Class gaw matut mahkai ai lam masum hpe madung tawn nna galaw ai:

Grade hpe tsun da ai raitim class hpe asan sha n hkan sa ai shaloi, typical failure mode gaw pipe n mai galaw ai ngu ai n re. Hten za ai lam gaw, jep joi ai shaloi, shingdu labau n htap htuk ai lam rai nga ai: RT shinggrup ai lam, nbung hpe tsi lajang ai lam a jahpan, hka jep ai lam a jahpan, dossier hkrang masa ni gaw, masing myit mada da ai hte n htap htuk ai.

Hpaga lam hta galai shai ai lam gaw gara kaw nna hpang wa ai

Welded pressure pipe a matu, galai shai ai lam hpe shara lahkawng hta grau nna jat wa shangun ai: hka hkin gau ntsa na plate hpe galaw ai lam hte hpaw ai-line geometry ngang grin ai lam. Ndai lahkam ni gaw, welding gaw ngang grin ai window kata kaw bungli galaw ai kun, shing nrai, ayan galai shai ai lam hta madung tawn ai kun ngu ai hpe dawdan ya ai.

Supply chain law law gaw coil kaw nna hpang nna, lahkawng lang ngu na galaw ai lam hku nna mai byin ai plate daw ni de galai shai wa ai:

FAQ

San: Q1: Grade hpe tsun da ai raitim, class hpe asan sha n tsun da ai rai yang hpa byin na kun?

A: A1: Grau sawng ai tsin-yam gaw, shut ai hku galaw shapraw ai lam n re, n chye na ai hkap la ai lamu ga jarit ni re. Hka lum ai masa, weld jep joi ai lam a shingdu labau, hydrotest ra ai lam ni, hte record format ni gaw n chye lu ai sha naw nga ai rai nna, hold point ni hta scope n htap htuk ai lam ni hpe law law lang byin shangun ai.

Q: Q2: Hpa majaw upstream plate galaw ai lam gaw welding ngang grin ai lam hpe dawdan chye ai kun?

A: A2: Hpa majaw nga yang, plate hkrang, jut dingyang, bevel n bung ai lam ni gaw, hpaw ai-line geometry hpe ngang grin ai kun ngu ai hpe dawdan ya ai. Stable geometry gaw root gap hte n htap htuk ai hpe hkang lu ai majaw, welding window hpe ngang grin shangun nna NDE gram lajang ai lam hta n-gun n rawng ai hpe shayawm ya lu ai.

San: Q3: Report n lawm ai majaw (sh) n htap htuk ai scope a majaw project ni grau hkrat sum ai kun?

A: A3: Scope n htap htuk ai majaw grau law ai. Purchase order ra ai lam ni, galaw sa wa na shara, report sakse ni n htap htuk ai majaw, asan sha chye na hkra galaw ai, jat nna jep joi ai lam, shing nrai, jahpan ni hpe daw mi bai galaw ai lam ni de du wa ai.

San: Q4: Dossier hta hkum tsup ai hta lai nna, hpa gaw ahkyak dik rai kun?

A: A4: Hkrang hte lamu ga sumla hpe hkan sa ai lam. Stable index logic, asan sha laika buk nambat masat ai lam, hte pat da ai-loop traceability mapping ni gaw, ngut sai pipe arai langai hpra hte shi a batch shiga ni hte hkrak sha report ni hpe galaw ya lu ai.
