Ntev Ncaj Welded Seam ASTM A500 API 5l LSAW Yeeb Nkab

ASTM A500 LSAW Steel Yeeb Nkab Siv Hauv Ntau Lub Hom Phiaj Engineering, Fencing, Scaffolding thiab lwm yam

Qhov sib txawv ntawm ASTM A500 GR A, B, C yog qhov sib txawv ntawm bai hauv cov khoom siv tshuab.

1. DuASTM yog lub npe luv ntawm American Society for Testing and Materials, yav tas los International Association for Testing Materials (IATM).

2. ASTM tus qauv lej yog: "Standard code + alphabetic classification code + standard serial number + year of formulation + Standard English name".

(1) Tus qauv code -- ASTM;

(2) Lub ntsiab lus ntawm tsab ntawv muab faib code: A -- hlau dub;

(3) Standard serial tooj -- 500, yog hais txog tus qauv specification rau cov kav dej thiab cov kav hlau puag ncig steel thiab seem hlau nyob rau hauv txias forming vuam thiab seamless carbon steel qauv. inch unit standard yam tsis muaj tsab ntawv M.
