ASTM A36 Rectangular Steel Tube

 

A36 steel yeeb nkab yog ib hom carbon structural steel yeeb nkab siv rau vuam thiab bolted hlau qauv hauv kev lag luam thiab kev tsim kho pej xeem, nrog rau kev tsim kho choj. ASTM A36 cov kav dej yog siv los tsim cov khoom lag luam thiab cov khoom siv rau kev tsim kho thiab kev siv tshuab engineering.

Yuav ua li cas txheeb xyuas qhov ua tau zoo tsis zoo A36 Rectangular Pipes

1. Cov kav dej tsis zoo yog qhov yooj yim rau folding. Folding yog hais txog ntau yam folds tsim nyob rau saum npoo ntawm cov yeeb nkab duab plaub, uas feem ntau txuas mus rau longitudinally thoob plaws tag nrho cov khoom. Yog vim li cas rau qhov tshwm sim ntawm folding yog tias inferior manufacturers nrhiav kev ua haujlwm siab, ua rau txo qis, ua rau pob ntseg, uas tom qab ntawd ua rau folding thaum lub sij hawm dov tom ntej. Cov khoom uas muaj folds yog qhov ua rau tawg tom qab khoov, uas ua rau muaj qhov txo qis hauv lub zog ntawm cov hlau.

2. Cov kav dej tsis zoo feem ntau pom muaj qhov pitted nto. Pitting yog ib qho teeb meem tshwm sim los ntawm qhov hnyav hnyav, ua rau muaj qhov tsis sib xws ntawm cov hlau. Vim tias cov yeeb nkab tsis zoo hauv cov yeeb nkab feem ntau nrhiav cov nyiaj tau los, qhov zawj dov feem ntau tawm ntawm qhov tshwj xeeb.

3. Qhov saum npoo ntawm cov kav dej tsis zoo yog qhov ua rau caws pliav. Muaj ob qho laj thawj: (1) cov khoom ntawm cov kav dej tsis zoo yog qhov tsis sib xws, muaj ntau yam impurities. (2) Inferior manufacturers muaj rudimentary cov cuab yeej thiab yog nquag rau steel sticking, ua rau cov impurities.

4. Qhov saum npoo ntawm cov ntaub ntawv tsis zoo yog qhov ua rau tawg vim qhov porosity siab ntawm cov billet, uas ua rau tawg thaum lub caij txias vim thermal stress. Cov kab nrib pleb no tshwm sim tom qab dov.

5. Inferior rectangular kav yuav raug khawb vim manufacturers muaj rudimentary cov cuab yeej, ua rau burrs uas khawb qhov saum npoo ntawm cov hlau. Sib sib zog nqus khawb txo lub zog ntawm cov hlau.

6. Cov kav dej tsis zoo hauv cov kav dej tsis muaj hlau nplaum vim yog ob qho laj thawj: ua ntej, lawv cov pob zeb yog ntxhib. Qhov thib ob, dov kub ntawm cov khoom tsis zoo tsis yog tus qauv; lawv ntsuas qhov kub ntawm cov hlau pom, ua rau nws tsis tuaj yeem yob raws li thaj tsam austenite, uas ua rau kev ua haujlwm tsis zoo.

7. Cov tav ntawm cov kav dej tsis zoo yog nyias thiab qis, feem ntau ua rau tsis txaus.

8. Qhov hla ntawm cov kav dej tsis zoo yog elliptical vim cov neeg tsim khoom, txhawm rau txuag cov ntaub ntawv, ntau dhau los txo cov thickness ntawm thawj ob kis ua ntej qhov kawg dhau. Qhov no zoo heev txo lub zog ntawm threaded steel thiab tsis ua raws li tus qauv qhov ntev ntawm threaded steel.

9. Cov hlau zoo muaj cov khoom sib xws, thiab lub tonnage ntawm lub tshuab txias shear yog siab, ua rau lub ntsej muag du thiab zoo huv si. Hauv qhov sib piv, cov ntaub ntawv tsis zoo feem ntau pom cov nqaij poob ntawm qhov kawg ntawm lub ntsej muag, piv txwv li, tsis sib xws, thiab tsis muaj xim hlau.

10. Cov kav dej tsis zoo muaj cov ntsiab lus impurity siab, uas ua rau cov hlau tsis tshua muaj siab thiab muaj qhov sib txawv ntawm qhov loj. Yog tsis muaj vernier caliper, nws muaj peev xwm los luj thiab xyuas lawv.

11. Lub puab txoj kab uas hla loj ntawm inferior rectangular kav fluctuates ho.
