ASTM A252 Qib 3 Yeeb Nkab Pile

A252 specification muaj xws li peb qib (1, 2, thiab 3), thiab qib 3 yeeb nkab cov ntaub ntawv yog cov feem ntau xaiv.
ASTM A252 Lus Txhais

ASTM A252 yog ib qho kev qhia tshwj xeeb rau welded thiab seamless steel yeeb nkab pawg. Nws npog lub nominal phab ntsa tuab ntawm cylindrical steel kav, tsis suav nrog cov kav dej. Cov kav dej puag ncig no yog siv rau pawg tsav tsheb, ua si lub luag haujlwm ntawm kev thauj khoom mus tas li thiab cov kabmob siab. Tsis tas li ntawd, lawv tau siv los ua lub plhaub tank ntawm qhov chaw ua haujlwm rau sau cov pob zeb ua ke.

Tus qauv yog nyob rau hauv nti phaus (uas tseem tuaj yeem hloov mus rau SI units) los muab cov engineers lossis cov neeg tsim qauv siv cov ntaub ntawv A252 yeeb nkab ua lub hauv paus rau kev tsim lub zog.
Tus qauv txwv cov khoom P (phosphorus) mus rau qhov siab tshaj plaws ntawm 0.050%, vim tias P ua rau cov hlau nkig thiab, qhov tseem ceeb tshaj plaws, tsis tsim nyog rau kev ua haujlwm vuam. ASTM A252 tus qauv tshwj xeeb tsuas yog txhais cov ntsiab lus phosphorus, thiab lwm cov ntsiab lus yog nyob rau hauv txoj kab nrog cov ntaub ntawv carbon steel.

Xav txog hom kev tsim khoom, ASTM A252 yeeb nkab pawg tuaj yeem tsim los ntawm cov txheej txheem seamless lossis welded.
Seamless yeeb nkab piles

Seamless yeeb nkab piles tseem hu ua kub dov los yog txias drawn thiab kub nthuav seamless kav.
Welded yeeb nkab piles

Welded yeeb nkab pawg muaj xws li ERW (hluav taws xob tsis kam vuam), flash welding, fusion vuam lossis submerged arc vuam SSAW lossis LSAW. Longitudinal los yog kauv vuam.
Raw material manufacturing process

Cov hlau nyoos tuaj yeem tsim los ntawm kev qhib hearth, cov pa oxygen yooj yim, cov txheej txheem hluav taws xob rauv.
