Engineering Txheej txheem cej luam
ASTM A252 qib 3 cov yeeb nkab piles yog cov txheej txheem steel kav tsim kom hloov Axial thiab lateral ntsaws rau hauv av lossis pob zeb txheej, sib sau txhim kho lub hauv paus nruab nrab. Cov pawg no muab txhav tawv, muaj peev xwm, thiab ntev}}} ua haujlwm rau cov choj sib koom ua ke nrog cov choj, chaw nres nkoj, khaws cov chaw muaj.
Lawv cov ntsiab lus tseem ceeb:
- Lub qhov txaus nyob rau hauv cov khoom sib tw av
- Loj -} section ว Tiffness rau khoov tsis kam
- Kev thauj khoom zoo heev hloov ntawm cov tawv nqaij txhuam thiab cov kabmob kawg

Txoj kev tsim khoom thiab kev tsim kho cov qauv txheej txheem tswj hwm
ASTM A252 Qib 3 Yeeb Nkab Ntau txoj kev ua haujlwm raws pawg loj, cov kev xav tau, thiab cov phiaj xwm specifications:
- ERW (hluav taws xob tiv thaiv welded):
Haum rau cov cim piling qhov loj nrog txhim khu kev qha ntawm cov leeg muaj zog thiab cov nqi tau zoo rau av - kev ua haujlwm.
- LSAW (Longitudinal submerged Arc Welded):
Muab cov kab ke zoo tshaj plaws, cov phab ntsa tuab, thiab Weld ncaj ncees, zoo tagnrho rau cov qauv tseem ceeb xws li cov choj piers lossis sab nrauv lub zog.
- SSAW / KAUV WELDED:
Ua kom cov ciaj loj loj nrog ua kom zoo me ntsis thiab thauj khoom hloov chaw nyob hauv cov dej num sib sib zog nqus cov tub rog thiab chaw nres nkoj.
Kawg Kev Siv Kev Siv
Kom phim ntau cov av qeeg thiab tsav tsheb, cov feem yuav raug xa tawm raws li:
- Qhib -}}}
Tso cai rau cov av plug lossis pob zeb lub ntsaws rau nruab qhov twg sib txhuam tiv thaiv kev ua kom muaj peev xwm
- Kaw -}}}} Cov pawg uas muaj welded pawg khau
Kev Txhim Kho Cov Khoom Nkag mus rau hauv cov av ntom ntom ntom, txhim kho -}}} Pile puas tsuaj thaum tsav tsheb
Cov kev tsim kev tsim qauv no kom pawg neeg ncaj ncees nyob rau hauv kev nyuaj siab hloov thaum txhim kho kev thauj khoom thoob plaws hauv pawg lub neej ua haujlwm.

Cov hau kev zoo li no:
- Kev Cuam Tshuam Rauj Tsav
- Hydraulic / vibratory tsav
- Jetting hauv Sandy Seabeds
Cov txiaj ntsig tau zoo:
- Kev installation ceev nrog minimal khawb
- Muaj zog tau sib haum nrog cov rooj zaum infill & qhov cuab lub zog
- Kev them nyiaj tsis ruaj khov nyob rau hauv cua, yoj, lossis seismic chaw thau khoom
Qhov zoo tagnrho rau:
- Offshore thiab marine piling
- Chaw nres nkoj thiab quay phab ntsa
- Lub hauv paus pej xeem
- Loj muaj qauv qauv
