304 & 316 Stainless Hlau Seamless Tubes - Engineered rau kev ntseeg siab heev
Stainless hlau seamless kav yog lub lifelines ntawm niaj hnub kev lag luam. Peb304thiab316austenitic stainless hlau seamless raj yog tsim los xa cov khoom tshwj xeeb corrosion kuj, siab - kub stability, thiab meej qhov sib xws. Txawm hais tias rau offshore roj platforms lossis aseptic kws tshuaj kab, peb muab cov kev daws teeb meem zoo uas ua kom muaj kev ua haujlwm zoo thiab cov kua dej purity.
Cov khoom sib sib zog nqus Dive: Tshaj cov lej qib
1. 304 Stainless Hlau (UNS S30400) - Ntau yam ua haujlwm
Chemical Highlights: Kwv yees li . 18% Chromium thiab 8% Nickel. Muab zoo heev dav dav corrosion kuj thiab zoo formability.
Ua kom pom tseeb: Haum rau ib puag ncig yam tsis muaj tshuaj chloride hnyav, muab kev txhim khu kev qha intergranular corrosion kuj.
Kev Pabcuam Kub: Khaws oxidation tsis kam rau kev pabcuam txuas mus txog 800 degree.
2. 316 Stainless Hlau (UNS S31600) - Cov Tshuaj tua hluav taws
Chemical Highlights: Muaj 2.0% -3.0% Molybdenum thiab ntau dua Nickel cov ntsiab lus.
Ua kom pom tseeb: Molybdenum ua kom muaj zog tiv thaiv pitting thiab crevice corrosion, tshwj xeeb tshaj yog tiv thaiv chlorides, sulfates, thiab dilute acids.
Kev Pabcuam Kub: Superior creep rupture zog ntawm qhov kub siab tshaj piv rau 304.
| Mechanical Property | Qib 304 | Qib 316 |
|---|---|---|
| Tensile zog (MPa) | Ntau dua lossis sib npaug li 520 | Ntau dua lossis sib npaug li 520 |
| Yield zog (MPa) | Ntau dua lossis sib npaug rau 205 | Ntau dua lossis sib npaug li 210 |

Advanced Manufacturing txheej txheem
Peb siv qhov nruj"Piercing → Multi- dhau Cold Drawing / Cold Rolling → Intermediate Solution Annealing → Straightening → NDT"ntau lawm khiav.
Kev daws Annealing: Ua nyob rau hauv kev tswj cov cua sov kom tshem tawm kev ua hauj lwm hardening thiab restore uniform austenitic qauv. Cov qoob loo loj yog khaws cia ntawm Qib 7 lossis finer.
Precision Tolerances: High-cov dov mills ua kom OD tolerances nyob rau hauv ± 0.05mm, nrog tsawg phab ntsa thickness sib txawv, yooj yim khoov thiab coiling yooj yim.
Smooth ID Nto: Los ntawm pickling lossis ci annealing, peb ua tiav Ra Tsawg dua lossis sib npaug ntawm 0.4μm sab hauv, txo qis kev sib txhuam thiab tiv thaiv kev loj hlob ntawm cov kab mob.
Kev lag luam-Cov ntawv thov tshwj xeeb
| Kev lag luam | Daim ntawv thov | Pom zoo Qib |
|---|---|---|
| Roj & Roj | Downhole instrumentation, subsea pipelines, refinery tshav kub exchangers | 316 / 316L |
| Khoom noj & dej haus | Npias brewing, mis nyuj pasteurization, potable dej kab | 304 (Polished ID) |
| Bio-Pharma | WFI (Dej rau Txhaj) loops, fermenter txias coils | 316L (Cov pa roj carbon tsawg) |
| Marine Engineering | Ballast dej systems, offshore firefighting kav, desalination | 316 / Duplex lwm txoj |
| Semiconductor | High -purity gas (N2) & tshuaj tis (EP qib) | 316L (Electropolished) |
| Kev tsim vaj tsev | Choj railings, structural kab, kab hlau rhuav phab ntsa thav duab | 304 / 304L |
Export Ntim & Logistics
Standard Bundling: Hexagonal steel-framed bundles qhwv hauv cov ntaub tsis muaj dej.
Kev Tiv Thaiv Kawg: Lub kaus mom yas ntawm ob qhov kawg kom tiv thaiv kev nkag ntawm cov khib nyiab.
Ntoo Case: Fumigation -dawb plywood rooj rau polished los yog me me - txoj kab uas hla coiled raj.
Lub Sijhawm Lead: 7-15 hnub ua haujlwm rau qhov ntau thiab tsawg; kev cai txiav txim sib tham raws li complexity.
