ASTM A53 Seamless Steel Yeeb Nkab yog tsim los tsis muaj vuam seam, muab cov qauv zoo tshaj plaws thiab kev sib haum xeeb. Nws yog tsim los ntawm kub- cov txheej txheem ua haujlwm, nrog rau kev xaiv txias tiav, ua rau nws zoo tagnrho rau siab - ib puag ncig siab thiab cov ntawv thov kev lag luam tseem ceeb uas qhov kev ncaj ncees weld tej zaum yuav muaj kev txhawj xeeb.

Kev tsim khoom

ASTM A53 Seamless Steel kav yog tsim los siv ob txoj hauv kev, txhua qhov muab qhov zoo sib xws:

Kub-Rolled Seamless Yeeb Nkab

Cov txheej txheem: Cov khoom steel hlau yog rhuab mus rau 1100℃-1250 degree, pierced los ua ib tug hollow raj, thiab ces dov thiab loj.

Cov yam ntxwv: Kev ua haujlwm siab ntau lawm, haum rau loj - txoj kab uas hla thiab tuab - cov kav dej. Deg roughness tej zaum yuav siab dua me ntsis piv rau cov khaub thuas- cov hlab.

Daim ntawv thov: General industrial piping, structural supports, and large -scale fluid transport.

Txias -Drawn Seamless Pipe

Cov txheej txheem: Kub- cov raj ua tiav tau ua tiav ntxiv nrog rau kev sib xyaw ua ke, kev sib tw, thiab ntau yam- dhau qhov kos duab txias kom ua tiav qhov ntev.

Yam ntxwv: Superior dimensional precision (OD kam rau ua ± 0.1mm), zoo heev nto tiav, thiab txhim kho cov khoom siv kho mob vim kev ua hauj lwm hardening.

Daim ntawv thov: Hydraulic thooj voos kheej kheej, precision machinery qhov chaw, thiab me me - txoj kab uas hla nyias - cov phab ntsa uas yuav tsum tau nruj tolerances.

Tshuaj muaj pes tsawg leeg

Qhov feem pua siab tshaj plaws rau cov ntsiab lus tseem ceeb yog raws li hauv qab no:

Element	Qib A, max (%)	Qib B, max (%)
Cov pa roj carbon (C)	0.25	0.30
Manganese (Mn)	0.95	1.20
Phosphorus (P)	0.05	0.05
Sulfur (S)	0.045	0.045
Copper (Cu) *	0.40	0.40
Nickel (Ni) *	0.40	0.40
Chromium (Cr) *	0.40	0.40
Molybdenum (Mo) *	0.15	0.15
Vanadium (V) *	0.08	0.08

* Ceeb toom: Tag nrho cov muaj pes tsawg leeg rau tsib alloying ntsiab (Cu, Ni, Cr, Mo, V) yuav tsum tsis pub tshaj 1.00%. cov

Mechanical Properties

Qhov tseem ceeb ntawm qhov sib txawv ntawm Qib A thiab Qib B yog nyob rau hauv lawv lub zog txhua yam, ua rau Qib B yog qhov kev xaiv rau siab dua - kev siv kev ntxhov siab. cov

Khoom	Qib A, yam tsawg kawg nkaus	Qib B, yam tsawg kawg nkaus
Tensile zog	48,000 psi (330 MPa)	60,000 psi (415 MPa)
Yield zog	30,000 psi (205 MPa)	69,000 psi (240 MPa)

Kev kho saum npoo

Thaum cov khoom siv hauv paus yog carbon hlau, ASTM A53 cov kav dej tuaj yeem muab nrog cov txheej txheem sib txawv los txhim kho kev ua haujlwm:

‌Dub Hlau: Uncoated, featuring tsaus oxide tiav los ntawm kev tsim khoom. Tus nqi - zoo rau qhov chaw nyob sab hauv lossis tiv thaiv ib puag ncig.

‌Kub-Dipped Galvanized‌: Coated with zinc (minimum 1.8 oz/ft²) to provide superior corrosion resistance. Ideal for outdoor, underground, or humid environments. Note: Galvanized pipes are not recommended for high-temperature applications (>390℃F) raws li zinc txheej yuav degrade
