EN10216-5 Seamless Steel Tubes para keng Pressure Purposes keng Matas a Temperatura - Technical Delivery Conditions
Impormasyun keng Pamag-order
Deng mamisali kailangan lang i-specify:
- Dagul (kaba, bilang da reng tubo)
- sukad (kilwal a diametru, kapal ning pader)
- Steel grade (eg, 1.4301, 1.4404)
- Delivery condition (eg, solution annealed)
- Kailangan keng pamagsuri (alimbawa, e makasira a pamagsuri, hydrostatic pressure)
- Nanu mang espesyal a kailangan (alimbawa, partikular a kalinisan para kareng aplikasyun ning nukleyar).
Steel Grades & Chemical Composition
Ing standard sasakupan nala deng austenitic stainless steels, kayabe nala reng:
- Standard grades: 1.4301 (304), 1.4404 (316L), 1.4541 (321), 1.4571 (316Ti), atbp.
- Matas a temperatura: 1.4919, 1.4958, atbp.
- Deng limitasyun ning komposisyun para keng C, Si, Mn, P, S, Cr, Ni, Mo, N, atbp., makasulat la.
Kondisyun ning Pamaglalang at Pamagdala
- Paralan ning pamaglalang: Alang tahi, marimla/mapali a meyari.
- Heat treatment: Solution annealing (mandatory para kareng austenitic steels).
- Surface finish: Ala yang scale, bitag, ampo depektu; kailangan ing pamag-atsara o pamag-passiv.
kailangan keng pamagsuri ampo pamagsuri
1 Mechanical Properties
- Tensile test (Rm, Rp0.2, elongation)
- Hardness test (nung kailangan)
2 Non-Destructive Testing (NDT)
- Eddy current o ultrasonic testing para akit ing depektu.
- Hydrostatic testing (optional, maliban nung makasulat).
3 Aliwang Pamagsubuk
- Grain size assessment (para kareng mapilan a gradu)
- Intergranular corrosion test (alimbawa, Strauss test para keng sensitization).
Pamarka & Sertipikasyun
- Deng tubo dapat makamarka la kareng:
- Lagyu/logo ning gagawang
- Steel grade
- Dimensions
- Heat number
- Standard reference (EN 10216-5).
- Inspection Certificate 3.1 o 3.2 (EN 10204).
Tolerance & Dimensions
- Sasaklo na ing tolerances para keng outer diameter, kapal ning pader, katuliran, ampo kaba.

Tala kareng Gradu ning Bakal
- Deng gradu kalupa ning 1.4301 (304) ampo 1.4404 (316L) ila reng peka karaniwan a gagamitan.
- Duplex steels (1.4462, 1.4410) atin lang mas matas a sikanan ampo resistance keng corrosion.
- Deng matas a temperatura (1.4958, 1.4959) magagamit la keng matinding kundisyun (alimbawa, petrochemical furnaces).
- Deng low-carbon variants (eg, 1.4306, 1.4404) mas buri da para keng welding applications.
