ASTM A312 yog ib qho tshwj xeeb rau cov yeeb nkab seamless, uas tseem npog cov yeeb nkab welded. ASTM A312 SEAMENT YEEB RAU KEV PAB COB RAU KEV PAB Nws sib ntsib ASTM A312 thiab tau siv dav hauv kev kub ntxhov ua ke rau API 560. Astm A312. Tsim los ntawm cov ntawv thov kub thiab kev pabcuam dav dav. Los ntawm tsis xav tau ib tug vuam txheej txheem, seamless yeeb nkab muaj kev ua haujlwm zoo dua piv rau welded yeeb nkab.
Peb muab ASTM A312 TP304 seamless stainless hlau yeeb nrog ntau xyoo ntawm kev paub. Lub ATTM A312 kev paub tshwj xeeb nrog qib TPP350 NPI rau cov yeeb nkab thiab qhov ntev hauv NPS ntau ntawm 1/8 nti rau 30 ntiv taw, nrog cov thicknesses nyob rau lub sij hawm ntawm sch 5 rau sch 160.

Cov ntawv thov nyob rau hauv kev kub siab (API 560)
TPPTICS STANLESS KHIAV PIPES YOG CRUCIANTIONSION PIPES yog qhov tseem ceeb hauv kev kub ua kom sov, siv dav hauv cov petrochemical, kho kom zoo thiab muaj zog tiam kev lag luam. Cov cua sov no cia siab rau kev ua haujlwm zoo tubing kom muaj cua sov kom zoo hloov cua sov nyob rau hauv huab cua sov thiab siab.
Tubes yooj yim (du hlab du)
Lawv tau siv rau hauv cov ntu kev sib tham thiab radiant coils vim lawv zoo heev thermal conductivity thiab corrosion tsis kam.
Nce Leeg
TPP34 yog cov khoom siv hauv paus uas xav tau rau kev tsim cov leeg ua kom zoo, txhim kho tshav kub hloov efficiency hauv kev tso cua sov. Tso cua sov ua raws li API 560 tau txais txiaj ntsig los ntawm lub zog siab thiab oxidation tsis kam ntawm Tp304, ua rau kev xaiv txhim khu kev qha rau cov ntawv tseem ceeb.
Txog kev ceev, qhov txiaj ntsig loj tshaj plaws yog qhov ntau thiab tsawg ntawm AISI 304 cov yeeb nkab yog hauv Tshuag hauv peb cov chaw khaws khoom hauv Suav teb. GNEE tuaj yeem xa cov khoom siv sai sai rau Middle East thiab Mena lub tebchaws, muab cov khoom xa khoom rau kev txiav txim siab. Raws li cov export ntim ntim ntawm 10 xyoo dhau los, GNEE yog nyob ntawm kaum tus neeg xa khoom ntawm SS 304 yeeb nkab hauv Suav teb. Peb tsuas yog muab cov khoom siv uas ua tiav raws li EN 10204 hom 3.1 MTC tus qauv.
Ntawm GNEE, cov neeg yuav khoom ntawm UNT S30400 cov yeeb nkab tuaj yeem sib piv cov ntawv thiab cov ntaub ntawv cov ntaub ntawv los ntawm kev txhim khu kev qha cov tshuab hluav taws xob hauv Suav teb thiab Europe. Tau txais cov lus pub dawb tam sim no!es@gescosteel.com
