1 Technical Requirements rausiab zog bolts qib

1) High-strength bolts yuav tsum tau raws li nram no specifications:

Cov kev qhia ntawm lub zog siab bolts yuav tsum ua tau raws li qhov yuav tsum tau muaj ntawmASTM A325 steel qauv ntsia liaj qhov roojQib thiab hom, ASTM F436 hardened steel washers specifications, thiab ASTM A563 txiv ntseej.

2) Ntxiv rau qhov ua tau raws li cov qauv ntawm ASTM A325 thiab ASTM A307, lub geometry ntawm lub bolt yuav tsum tau ua raws li cov kev cai ntawm B18.2.1 hauv ANSI. Ntxiv rau qhov ua tau raws li cov qauv ntawm ASTMA 563, txiv ntseej yuav tsum ua kom tau raws li cov cai ntawm ANSI B18.2.2.

3) Cov neeg muag khoom tau lees paub lub zog muaj zog bolts, txiv ntseej, ntxhua khaub ncaws thiab lwm qhov chaw ntawm kev sib dhos kom ruaj khov kom ntseeg tau tias cov bolts yuav siv tau raug txheeb xyuas thiab ua tau raws li cov kev cai ntawm ASTM specifications. High-strength bolts yog sib sau ua ke los ntawm cov chaw tsim tshuaj paus nyob rau hauv batch Rau cov khoom, cov chaw tsim tshuaj paus yuav tsum muab ib tug zoo guarantee daim ntawv pov thawj rau ib batch.

4) Tus neeg muag khoom yuav tsum muab cov txiv ntseej roj uas tau sim nrog lub zog siab bolts muab.

2. siab zog bolts rau steel qauvKev ruaj ntseg ntawm bolts

1) High-lub zog boltsyuav tsum tau los nag-pov thawj, noo noo-pov thawj, thiab kaw thaum lub sij hawm thauj mus los thiab cia, thiab yuav tsum tau muab ntsia thiab unloaded maj mam los tiv thaiv kev puas tsuaj rau threads.

2) Tom qab lub zog muaj zog bolts nkag mus rau hauv qhov chaw, lawv yuav tsum raug tshuaj xyuas raws li cov cai. Tsuas yog tom qab dhau qhov kev tshuaj xyuas nws tuaj yeem muab tso rau hauv cov khoom muag thiab siv rau kev tsim khoom.

3) Txhua batch ntawmmuaj zog boltsyuav tsum muaj daim ntawv pov thawj Hoobkas. Ua ntej cov bolts tau muab tso rau hauv qhov chaw cia, txhua pawg ntawm bolts yuav tsum tau kuaj thiab tshuaj xyuas. Thaum lub zog muaj zog bolts tau muab tso rau hauv qhov chaw cia, cov chaw tsim khoom, ntau npaum li cas, hom, hom, specification, thiab lwm yam. noo noo thiab plua plav thaum lub sijhawm khaws cia txhawm rau tiv thaiv corrosion thiab qhov chaw hloov pauv, qhib cia yog nruj me ntsis txwv.

4) Lub zog muaj zog bolts yuav tsum tau muab khaws cia rau hauv pawg raws li tus lej batch thiab cov lus qhia tshwj xeeb qhia ntawm lub thawv ntim khoom. Lawv yuav tsum tau muab khaws cia rau hauv cov nyiaj siv ua haujlwm sab hauv tsev thiab yuav tsum tsis txhob muab tso rau ntau tshaj tsib txheej. Tsis txhob qhib lub thawv ntawm lub siab thaum lub sijhawm khaws cia kom tsis txhob xeb thiab kis kab mob.

5) Ntawm qhov chaw teeb tsa, cov bolts yuav tsum tau muab tso rau hauv lub thawv kaw kom tsis txhob muaj plua plav thiab ya raws. Bolts uas muaj xeb thiab plua plav yuav tsum tsis txhob siv rau hauv kev tsim kho tshwj tsis yog tias lawv tsim nyog raws li ASTM F1852.
