API steel yeeb nkab

Cov Khoom Piav Qhia Alloy steel yeeb nkab yog cov yeeb nkab steel uas muaj cov ntsiab lus alloy xws li manganese, silicon, npib tsib xee, titanium, tooj liab, chromium thiab txhuas. Cov ntsiab lus alloying no tau ntxiv los txhim kho cov khoom siv kho tshuab thiab tshuaj lom neeg ntawm cov hlau. Alloy steel yeeb nkab yog ib qho zoo heev ...

Khoom Description

API 5L feem ntau yog hais txog cov yeeb nkab yeeb nkab (pipeline yeeb nkab) ntawm kev ua raws li tus qauv, cov yeeb nkab steel yeeb nkab nrog rau seamless steel yeeb nkab thiab welded steel yeeb nkab ob pawg. Tam sim no nyob rau hauv cov roj pipeline peb feem ntau siv welded steel yeeb nkab yeeb nkab hom kauv submerged arc welded yeeb nkab (SSAW), ncaj seam submerged arc welded yeeb nkab (LSAW), tsis kam welded yeeb nkab (ERW), seamless steel yeeb nkab feem ntau siv nyob rau hauv txoj kab uas hla. yog tsawg dua 152mm. GNEE Group muab API 5L yeeb nkab rau ntau qhov ntau thiab tsawg, koj tuaj yeem tiv tauj peb rau API 5L steel yeeb nkab txhua lub sijhawm.
