EN10216-5 Seamless Steel Tubes parad Gagala na Pressure ed Atagey a Temperatura - Teknikal iran Kondisyon na Pangiter
Impormasyon ed Panag-order
Saray manaliw et nepeg ya mangibaga:
- Karakel (karukey, bilang na tubo)
- Sukat (diametro ed paway, kapal na padir)
- Steel grade (alimbawa, 1.4301, 1.4404)
- Kondisyon na pangiter (alimbawa, solusyon ya in-anneal)
- Saray kakaukolanen ed inspeksion (alimbawa, ag-makaderal a panagsukimat, hydrostatic pressure)
- Antokaman ya espisyal iran kakaukolanen (alimbawa, espisipikon kalinisan parad saray aplikasyon ed nukleyar).
Saray Grado na Asero tan Kemikal ya Komposisyon
Say estandarte et mansaklaw ed saray austenitic stainless steel, kaiba lay:
- Standard grades: 1.4301 (304), 1.4404 (316L), 1.4541 (321), 1.4571 (316Ti), tan arum nira.
- Saray grado ed atagey a temperatura: 1.4919, 1.4958, tan arum nira.
- Saray limitasyon na komposisyon parad C, Si, Mn, P, S, Cr, Ni, Mo, N, tan arum nira, et nibaga.
Kondisyon na Panaggawa tan Pangiter
- Paraan na produksyon: Anggapoy tahi, ambetel/ampetang ya asumpal.
- Heat treatment: Solution annealing (mandatory parad austenitic steels).
- Say tapew: Anggapoy sukat, bitak, tan depekto; nayarin kaukolan so panag-atsara odino panagpasibo.
Saray Kakaukolanen ed Inspeksyon tan Pansubok
1 Mekanikal iran Kablian
- Tensile test (Rm, Rp0.2, elongation)
- Subok ed inka-malet (no nakaukolan)
2 Non-Destructive Testing (NDT)
- Eddy current o ultrasonic testing parad pakaamta na depekto.
- Hydrostatic testing (opsyonal, likud no nibaga).
3 Arum nin Subok
- Panangusisa ed kabaleg na bukel (parad pigaran grado)
- Intergranular corrosion test (alimbawa, Strauss test parad sensitization).
Marka tan Sertipikasyon
- Saray tubo et nepeg ya akamarka na:
- Ngaran/logo na manggagawa
- Grado na asero
- Sukat
- Numero na petang
- Standard reference (EN 10216-5).
- Inspection Certificate 3.1 o 3.2 (EN 10204).
Panag-anos tan Sukat
- Sakop to ray tolerances parad paway a diametro, kapal na padir, inkapeteg, tan karukey.
