Kev piav qhia
Cov yeeb nkab li qub yog cov hauv paus hauv cov yeeb nkab, li qub, thiab fittings tab sis kuj muaj cov txheej txheem kev daws teeb meem rau chav dej, dej kub, humidification, valve actuation, tswj, instrumentation, huv cov txheej txheem, corrosive kua tuav, thiab coj mus muag kav dej thiab kua.

Specification
DIAMETER RANGE
Peb cov li qub muaj rau 2 txog 60 nti yeeb nkab diameters. Tham nrog pab pawg ntawm Union Steel rau qhov loj dua.
TSHUAJ CLASS
Union Steel manufactures li qub raws li CWP, ANSI 150, ANSI 300 thiab ANSI 600 tus qauv. Los ntawm lub ntiajteb txawj nqus uas tsis tshua muaj siab pub rau cov tshuab nrog 1500 PSI.
VALVE lub cev & TRIM khoom
Union Steel li qub tsis muaj kev txwv rau cov khoom siv xws li Stainless Hlau, Titanium lossis Platinum.
Raws li kev siv metallurgy yog nyob ntawm daim ntawv thov tshwj xeeb, peb cov tswj valve muaj nyob rau hauv kaum ob ntawm cov qauv thiab cov khoom sib txawv (xws li Carbon steel, 316 Stainless hlau, Hastelloy, SuperDuplex, Titanium, thiab lwm yam).
Txuj
Nyob ntawm koj qhov kev npaj siv, koj yuav pom tias cov li qub yuav tsum ua raws li cov qauv tshwj xeeb kom ua tau raws li kev cai tswj hwm kev nyab xeeb, kev huv huv, lossis lwm yam kev txhawj xeeb. Txawm hais tias muaj ntau lub koom haum txheej txheem thiab cov kev cai muaj peev xwm los npog kom meej, cov koom haum txheej txheem feem ntau suav nrog:
CSA Group (CSA)
Lub koom haum American Society of Mechanical Engineers (ASME)
Lub koom haum American National Standards Institute (ANSI)
American Society for Testing Materials International (ASTM International)
Lub Koom Haum Tsim Qauv Txheej Txheem (MSS)
Lub koom haum International rau Standardization (ISO)
Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv thiab Kev Nyab Xeeb (NSF)
NACE International (NACE)
Lub koom haum American Petroleum (API)
American Water Works Association (AWWA)
Kuj tseem muaj kev lag luam- cov qauv tshwj xeeb los xav txog.
Cov koom haum loj tshaj plaws los ntawm kev lag luam muaj xws li:
ASHRAE Valve Standards
ASME BPVC Valve Standards
