Peb cov duplex hlau threaded rods ua raws li ASTM A193 thiab siv 2205 duplex khoom. Qhov no ua rau muaj tensile lub zog ntawm 700-850 MPa, siab dua li cov rods hlau tsis zoo tib yam yam yam, thiab tiv thaiv xeb heev hauv cov dej qab ntsev lom neeg.
Peb muaj ob txoj kev kho saum npoo: pickling (raws li ASTM A380) rau kev tiv thaiv corrosion zoo dua, thiab oiling (light mineral oil) los tiv thaiv cov xov tooj thaum khaws cia. Tus thib peb pickling tawm tawm cov zeb uas tsim thaum tsim khoom.
Peb cov xov yog precision-machined: UNC threads (ASME B1.1). Peb tuaj yeem xav pom cov rod rau qhov ntev customized (1 txog 6 meters) siv high-speed saws kom cov rod xov zoo. tag nrho rod raug tub ceev xwm gauge (raws li ASME B1.1) ua ntej xa khoom kom paub tseeb tias qhov loj ntawm xov xwm.
Raws li ib tug suav manufacturers uas tau pab cov neeg siv khoom nyob sab Europe thiab American industrial, peb muaj cov kab threading tshwj xeeb thiab cov tshuab cua sov kho, nrog lub peev xwm tsim xyoo 3,000 tons. Peb cov raw cov ntaub ntawv tau txais kev kho mob annealing pov thawj xeeb kom ua tiav 50-50 ferrite/austenite sib pab thiab raug kaw hauv tsev siv magnetic particle detectors.
Peb lub tsev khaws khoom 600-800 tons ntawm cov khoom muag, npog txoj kab uas hla ntawm 1/4 inch txog 2 inches nrog qhov ntev ntawm 3 thiab 6 meters. Peb lub vev xaib tshiab tshaj tawm cov ntaub ntawv khoom siv txhua hnub, thiab cov khoom xa tuaj ntawm cov khoom muag tuaj yeem xa tawm hauv 5 hnub.
Kev txiav txim siab tshaj 40 tons have gotten 5% luv nqi, free processing service.
Nov yog peb qhov kev lees paub: Yog tias muaj Duplex Steel Tsis Txhob Threaded Rod twg tsis ua raws li ASTM A193 lub zog cov qauv lossis qhia tias muaj corrosion loj (ntau dua 0.01mm/xyoo) hauv cov kev pabcuam hauv 3 xyoo, peb yuav pab nws hauv 7 hnub thiab lawv tag nrho cov nqi xa khoom. Peb kuj saib xyuas nqi rau 40 hnub ntawm cov kev txiav txim uas tau lees paub, kom koj tsis txhob poob siab txog qhov nqi tam sim no pab txhawb koj cov nyiaj tau.
