Khoom Description
Peb Qhov Zoo
1. Muaj zog muaj zog zoo
- Duplex Seamless Yeeb Nkab muaj lub zog tawm los kwv yees li ob npaug ntawm cov hlau tsis zoo li austenitic, tso cai rau cov phab ntsa nyias nyias thaum tuav cov yeeb nkab muaj zog. Qhov no txo cov nqi thaum tswj kav dej nyab xeeb thiab zoo.
- Cov kav dej tau raug kuaj xyuas cov cuab yeej nruj kom ntseeg tau tias txhua yam kev ua tau zoo raws li ASTM A790 / A789 cov qauv lossis cov neeg siv khoom xav tau.
2. High Corrosion Resistance
- Hauv kev lag luam chemical thiab petrochemical, qhov twg yuav tsum tau sib cuag nrog cov xov xwm corrosive ntev, Duplex Seamless Pipe yog resistant rau corrosion los ntawm acids xws li sulfuric acid, hydrochloric acid, thiab phosphoric acid, nrog rau ntau yam tshuaj solvents, txo downtime thiab to txaus ntshai.
- Cov kav dej yog pickled los txhim kho lawv cov kev tiv thaiv corrosion, thiab kev sim tshuaj lom neeg muaj pes tsawg leeg kom ntseeg tau tias cov khoom siv raw siv tau raws li tus qauv specifications.
3. Kev kub siab ua haujlwm
- Peb cov kav dej yog seamless, duplex stainless hlau kav tsim los ntawm kev sib xyaw ntawm cov txheej txheem kub extrusion thiab txias txheej txheem, ua rau cov phab ntsa tuab. Ultrasonic kuaj thiab kuaj hydrostatic kom muaj kev pheej hmoo tsawg kawg ntawm kev tawg lossis deformation.
- Peb cov kav dej tuaj yeem tiv taus qhov kub siab txog li 662℃F thaum tuav lub zog txhua yam, ua rau lawv zoo tagnrho rau kev siv siab - kub thiab siab - siab.
4. Kev Pabcuam
- Peb muab cov kev kho deg, suav nrog pickling thiab passivation, mechanical polishing (nrog rau qhov roughness Ra tsawg dua lossis sib npaug li 0.8 μm), sandblasting, electropolishing, nrog rau chamfering thiab deburring.
- Peb txhawb tsis yog -tus qauv customization, muab kev ua tiav xws li threading, flanging, chamfering, thiab beveling, nrog rau lub kaum sab xis ntawm ± 0.5 degree, sib xws nrog cov qauv vuam.
thaj chaw thov
- Roj thiab Roj: High-cov kav dej siab, cov dej hauv qab dej hiav txwv, cov chaw sab nrauv, cov chaw tsim hluav taws xob, thiab lwm yam.
- Tshuaj thiab PetrochemicalCov txheej txheem piping, reactors, tshav kub exchangers, tshuaj cia tank, thiab lwm yam.
- Kev siv dej hiav txwv: Rov qab osmosis systems, seawater intake / discharge pipelines, cooling systems
- Lub zog thiab lub zog: Siv nyob rau hauv tshav kub exchangers, boiler tubes, txias dej systems
- Kev lag luam ntawv: Chemical digesters, bleaching txheej txheem kab, thiab lwm yam.
