Stainless Steel Seamless Pipe Production Process

1.N-gun n rawng ai (SMLS)

Ladat: Billet hpe katsi ai → Htu ai → Htu ai → Sizing → Hka hpe n-gun jaw ai → Htu ai → Chyam dinglik ai.
Akyu: Weld seam n nga ai, -pressure kaba hte ahkyak ai magam bungli a matu kam mai ai.

2.Galaw da ai (ERW/EFW)

Ladat: Strip (sh) plate hpe galaw ai → Longitud/spiral hku shingjawng ai → Hka hpe n-gun dat ai → Sizing → Dingyang galaw ai.
Welding galaw ai ladat ni gaw OD/WT hta hkan nna ERW/HFI, TIG/GTAW, SAW, EFW ni hpe galaw ai.
Akyu: Manu jahpu-htuk manu ai, galu kaba ai, bead hpe shaw kau ai hte san seng ai lam ni hpe lata la mai ai.

3.Grai katsi ai bungli galaw ai (HCW)

Ladat: Welded pipe ntsa kaw katsi ai hpe shayawm ai + annealing galaw ai.
Akyu: N-gun ja wa ai, hkam sharang ai lam grau ngang kang ai, ngut kre ai lam grau hkrak wa ai.

4.Hka lum ai hte ntsa lam

1050-1150℃lawan ai hku hkru mat ai.
Ntsa lam hta lata la mai ai lam ni: Annealed & pickled, htoi tu ai, satin-hprawng ai, shingran-hprawng ai.

5.Quality hpe hkang ai

Hka n-gun hpe chyam yu ai, Eddy Current/UT, Seam & hkum hkrang ntsa Radiography galaw ai.
Mechanical chyam dinglik ai lam: Tensile, n-gun, ngang kang ai, n-gun n-gun/htum mat ai.
Laksan hku nna, n-gun n rawng ai hpe chyam yu ai: ASTM A262 (IGC), ASTM G48 (hpyen n-gun n rawng ai).
