Material & Manufacturing txheej txheem
Mechanical kev nyab xeeb nyob rau hauv siab -siab ntim cia siab rau lub meej metallurgical tswj thiab automated thermal ua.
Raw Khoom:Tau txais tshwj xeeb los ntawm hwm 34CrMo4 seamless steel tube billets. Txhua batch suav nrog daim ntawv pov thawj Mill Test Certificate (MTC) qhia txog cov tshuaj muaj pes tsawg leeg txwv (C: 0.30-0.37%, Cr: 0.90-1.20%, Mo: 0.15-0.30%).
Kub Spinning Tsim:Billet xaus rau kev tswj induction cua sov ua raws li computerized kub-spinning kom zoo ib yam, kev nyuaj siab-dawb dome profiles yam tsis muaj welding seams.
Quenching & Tempering (Q&T): Full-body thermal treatment via automated vertical quench lines ensures uniform martensitic transformation, followed by precise high-temperature tempering to achieve optimal yield-to-tensile strength ratios (Yield Strength >= 750 MPa, Tensile Strength >= 850 MPa).
Internal Surface Txhaj Tshuaj Blasting:Mechanical descaling thiab tu tshem tawm cov txheej txheem oxidation sab hauv, tiv thaiv cov kab mob sib kis hauv cov dej hauv qab cov roj injectors lossis regulators.
Kev Tswj Xyuas Zoo & Kev Xeem yuav tsum tau ua
Txhua qhov ntau lawm ua rau muaj kev puas tsuaj thiab tsis yog -kev kuaj kev puas tsuaj (NDT) ua pov thawj los ntawm cov chaw soj ntsuam ywj pheej (TUV, BV, lossis SGS).
Kev kuaj ultrasonic (UT):100% volumetric tshuaj xyuas ntawm phab ntsa cylindrical thiab caj dab ntu kom pom cov laminations sab hauv lossis kev suav nrog.
Hydrostatic Pressure Test:Txhua lub tog raj kheej yog pressurized rau 1.5 npaug ntawm kev ua hauj lwm siab (300 bar los yog 375 bar) nyob rau tsawg kawg yog 30 vib nas this los xyuas kom meej elastic deformation txwv.
Kev ntsuam xyuas tawg:Ua nyob rau ntawm qhov sib piv ntawm 1 lub tog raj kheej ib pawg ntawm 200 units, ntsuas volumetric expansion thiab xyuas kom meej tias tawg siab tshaj 2.25 lub sij hawm ua hauj lwm siab yam tsis muaj fragmentation.
Flattening & Tensile Tests:Transverse thiab longitudinal daim coupon rub los ntawm lub plhaub tiav kom paub meej tias elongation thiab tensile thresholds ua tau raws li ISO 11439 cov qauv.
Internal Corrosion & Hydrogen Embrittlement Resistance:Saib xyuas ntawm microstructural grain loj tsom xam (ASTM E112 raws).
Tej kev siv
Engineered rau kev koom ua ke rau hauv siab - kev vibration tsheb chassis thiab siab -flow industrial gas distributions setups.
Commercial Fleets:Roj cia rau CNG- tsheb npav thauj mus los, tsheb thauj khoom khib nyiab hauv nroog, thiab ntev - tsheb laij teb logistics.
Chaw Nres Tsheb Cascade Systems:Modular storage banks rau CNG fueling stations, muab qhov chaw cia rau ceev ceev -fill dispenser operations.
Mobile Thauj Skids:Containerized gas thauj modules txav compressed natural gas los ntawm qhov zoo los yog thawj daim phiaj txhaj cov ntsiab lus mus rau tej thaj chaw deb cov neeg siv khoom.
Procurement & Supply Chain Parameters
Yam tsawg kawg nkaus Order Quantity (MOQ):1 x 20-foot thawv (ntau npaum li cas los ntawm txoj kab uas hla thiab ntev matrix).
Packing Specifications:Lub tog raj kheej nkoj liab qab lossis nrog hnyav -lub luag haujlwm nylon tiv thaiv mesh nets, ruaj rau hauv cov ntoo pallets kom tiv thaiv kev cuam tshuam sab nrauv lossis xov puas thaum hla dej hiav txwv.

Cov lus nug nquag
Q: Dab tsi yog lub neej tsim qauv (kev pabcuam lub neej) ntawm cov hlau CNG thooj voos kheej kheej?
A: Ua raws li ISO 11439 cov kev cai, tus qauv kev ua haujlwm lub neej yog 20 xyoo (los yog cov voj voog tshwj xeeb raws li tau teev tseg los ntawm cov tub ceev xwm thauj hauv lub tebchaws), muab cov sijhawm ua kom tau raws li lub sijhawm.
Q: Koj puas tuaj yeem kho lub peev xwm dej lossis sab nraud rau qhov chaw txwv chassis?
A: Yog. OEM / ODM customization yog muaj rau cov ntim ntim ntau. Engineering layout drawings yog muab nyob rau hauv 48 teev rau cov neeg siv khoom integration kos npe -tawm ua ntej kev teeb tsa.
Q: Dab tsi xov specifications muaj rau lub tog raj kheej caj dab?
A: Cov txheej txheem tsim khoom siv PZ27.8 lossis W28.8 cov xov sab hauv. Parallel los yog lwm txoj xov tapered tuaj yeem ua raws li kev thov engineering kom phim cov valve tshwj xeeb.
Q: Koj ua li cas rau qhov thib peb - tog yuav tsum tau soj ntsuam?
A: Cov khoom lag luam niaj hnub raug tshuaj xyuas los ntawm cov chaw lees paub xws li TUV, Bureau Veritas, lossis SGS. Cov neeg yuav khoom kuj tuaj yeem xaiv lawv tus kheej thib peb -tus neeg saib xyuas cov neeg sawv cev los ua pov thawj hydrostatic thiab burst testing onsite ua ntej xa khoom.
Q: Qhov kev tiv thaiv corrosion yog siv rau sab nrauv sab nrauv?
A: Cov chaw sab nrauv tau txais kev ua kom tsis zoo ntawm cov grit blasting (Sa 2.5 qib), ua raws li electrostatic hmoov txheej (epoxy-polyester formulation) kho ntawm 200 degree, muab cov neeg kho tshuab cuam tshuam thiab ntsev- tshuaj tiv thaiv corrosion ntau tshaj 500 teev.
