Peb cov ASTM 310s Hex Bolts muaj kev tiv thaiv kub zoo heev qhov twg cov fasteners zoo tib yam khoov xeb.
Lub taub hau txias-forged muaj 600 MPa tensile zog, tseem ceeb boiler khi rods rau pyrolysis reactors. Koj yuav tau txais 3x lub neej ua haujlwm ntawm 304 bolts hauv oxidizing ib puag ncig. Txhua batch tuaj nrog EN 10204 3.1 certs lees paub chemistry thiab lub zog.
Peb muaj ob txoj kev ua tiav: Bright annealed rau qhov du thiab tu, thiab pickled (ASTM A380) Tso tawm cov cua sov scale los ntawm kev tsim khoom.
Peb cov threading yog ua nrog precision: UNC threads, kom haum nrog ceev. Peb kuj muab qhov ntev customized tolerance, siv txias heading tshuab uas tsis ua rau cov hlau tsis muaj zog. Txhua bolt tau txais 100% magnetic particle test (ASTM E709) zoo cov kab saum npoo ua ntej xa khoom.
Raws li ib tug Suav manufacturers muab khoom rau European thiab American industrial furnace makers. Peb cov raw khoom tau txais lub tshuab nqus tsev arc remelting (VAR), lav los ntawm peb lub tsev OES tshuab.
Peb khaws 180-300 tons hauv lub tsev khaws khoom, npog qhov ntau thiab tsawg ntawm ½" txog 2½" thiab ntev 2" txog 16". Cov ntaub ntawv tshiab tshiab txhua hnub hauv peb lub vev xaib, thiab xa tawm hauv 6 hnub - yooj yim kev ua tau raws li koj cov neeg siv khoom lub sijhawm tseem ceeb.
Kev txiav txim siab tshaj 30 tons tau txais 6% luv nqi, ntxiv rau dawb pickling thiab 18% ntawm hiav txwv freight.
Nov yog peb qhov kev lees paub: Yog tias muaj ASTM 310s Hex Bolt twg tsis ua raws li ASTM A193 mechanical standard of the kub siab, peb yuav xav nws hauv 7 hnub thiab lawv rov qab tag nrho cov nqi xa khoom. Peb kuj saib xyuas nqi rau 40 hnub ntawm cov kev txiav txim uas tau lees paub, nrog 2% lawm luv nqi yog tias koj rov nug dua hauv 60 hnub.

Cov Lus Nug Nquag Nug
Nug: Koj puas tuaj yeem qhia ib co ntawm koj cov neeg siv khoom siv los yog case studies?
Teb: Tau, peb tuaj yeem qhia cov ntaub ntawv tshawb fawb ntawm cov neeg siv khoom hauv koj qhov kev lag luam (xws li oil & gas, construction) thaum tiv thaiv lawv cov ntaub ntawv pov thawj tug.
Nug: Kev cai li cas rau kev xa rov qab yog lwm yam khoom?
Teb: Yog tias cov khoom lag luam muaj teeb meem zoo los ntawm peb, peb yuav npaj zoo li lawv rov qab hauv 30 hnub tom qab tau txais.
Nug: Koj puas tuaj yeem muab daim ntawv pov thawj keeb kwm (CO) rau kev tawm tawm kev lis kev cai?
Teb: Yog, peb tuaj yeem muab CO, nrog rau lwm cov ntaub ntawv xws li kev lag luam invoices thiab packing lists uas xav tau rau kev lis kev cai.
