BS1387 ERW Cov Khoom Siv Hluav Taws Xob

BS 1387 cov kav dej yog cov qauv British threaded thiab socketed steel kav rau kev xa dej. Lawv tuaj nyob rau hauv ob hom txheej: dub (uncoated) los yog galvanized (zinc-coated). Cov yeeb nkab kawg kev kho mob muaj xws li cov xaus, sab hauv threaded xaus, los yog lwm threaded xaus, haum rau ntau yam kev twb kev txuas.

BS 1387 Welded Steel Yeeb Nkab Kev Xeem:

1. Tensile Performance Test
Kev ntsuas ntawm Tensile Strength: Tensile lub zog yog qhov kev ntxhov siab sib haum rau qhov siab tshaj plaws quab yuam siv.
Kev ntsuas ntawm Upper Yield Strength: Qhov no tuaj yeem txiav txim siab los ntawm kev quab yuam-extension nkhaus lossis peak force zaub. Nws txhais tau tias yog qhov kev ntxhov siab sib raug rau qhov siab tshaj plaws quab yuam ua ntej thawj zaug poob hauv quab yuam. Upper yield zog yog xam los ntawm kev faib cov quab yuam no los ntawm qhov qub ntu ntu ntawm cov qauv.
Kev ntsuas ntawm elongation Tom qab Fracture: Cov pob txha tawg ntawm cov qauv yuav tsum tau ua tib zoo sib xyaw ua ke kom haum cov axis. Kev ntsuas tshwj xeeb yuav tsum tau coj los xyuas kom muaj kev sib cuag ntawm qhov tawg ua ntej ntsuas qhov ntsuas qhov ntev tom qab tawg. Lub elongation tom qab tawg yog ces suav nrog cov qauv tsim nyog.

2. Kev ntsuas kev ua tau zoo
Cov qauv yog muab tso rau nruab nrab ntawm ob daim hlau ntawm lub tshuab kuaj, kom ntseeg tau tias cov npoo ntawm cov qauv raug tso cai kom sib npaug lossis chamfered siv cov ntaub ntawv lossis lwm txoj hauv kev. Qhov dav ntawm daim hlau yuav tsum tshaj qhov dav ntawm cov qauv flattened. Cov phiajcim tau txav mus rau hauv ib qho kev taw qhia perpendicular mus rau longitudinal axis ntawm cov yeeb nkab, nrog rau kev txav tsis tshaj 25mm / min. Tom qab qhov kev xeem, cov qauv raug soj ntsuam yam tsis siv lub iav magnifying. Yog tias tsis pom cov kab nrib pleb pom, cov qauv raug suav tias tsim nyog. Kev tawg me me ntawm cov npoo npoo yuav tsum tsis yog lub hauv paus rau kev tsis lees paub.
