ASTM A252 Seamless Piling yeeb nkab
Nqe lus piav qhia:ASTM A252 GR.C SMLS Piling yeeb nkab, ASTM A252 GR.C Seamless Piling Yeeb
Txheem:ASTM A252, ASTM A252
Qib:GR.1, GR.2, GR.3

Loj:21.3MM -1020MM

Thickness:1.5MM -100MM

Sab nraud txoj kab uas hla tolerance:±1%

Phab ntsa thickness kam rau ua: ±12.5%

Ntev:12-22M, ib txwm 12M, kuj nyob ntawm koj qhov kev xav tau

Anti-corrosion txheej:Varnish txheej

Txheej txheem txheej txheem:

1. Xaiv cov khoom siv zoo. Carbon steel siv nyob rau hauv zus tau tej cov A252 seamless piling yeeb nkab

2. Cua sov thiab dov khoom steel yeeb nkab kom txog thaum xav tau qhov loj thiab cov duab tiav.

3. Ua cov txheej txheem kho cua sov. Cov kav dej yog rhuab mus rau qhov kub thiab txias thiab tom qab ntawd txias ntawm tus nqi tswj.

4. Kev Ntsuas: Tom qab cov txheej txheem kho cua sov ua tiav, cov kav dej yuav dhau los ua cov kev sim, nrog rau kev kuaj ultrasonic, kuaj hydrostatic thiab kuaj pom.

5. Kev ua tiav: Cov kauj ruam kawg hauv cov txheej txheem machining yog ua tiav cov yeeb nkab. Qhov no suav nrog kev txiav cov yeeb nkab kom ntev li ntev tau, siv cov txheej txheem tsim nyog los yog ua tiav, thiab npaj cov yeeb nkab rau kev thauj mus los.

Qhov sib txawv ntawm GR.1, GR.2, GR.3:

1. ASTM A252 GR.1: Qib 1 steel yog hom hlau uas siv ntau tshaj plaws thiab zoo tagnrho rau kev sib sib zog nqus hauv paus thiab kev txhawb nqa. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 30, 000 psi thiab lub zog tensile yam tsawg kawg nkaus ntawm 50, 000 psi. Nws yog tus cwj pwm los ntawm weldability thiab zoo cuam tshuam tsis kam.

2. ASTM A252 GR.2: Qib 2 steel muaj qhov siab tshaj qhov ua tau zoo ntawm 35, 000 psi thiab lub zog tensile yam tsawg kawg nkaus ntawm 60, 000 psi. Nws yog siv thaum xav tau los txhawb nqa hnyav dua lossis hnyav dua ib puag ncig.

3. ASTM A252 GR.3 Khoom: Qib 3 steel muaj qhov siab tshaj plaws tawm los thiab tensile zog ntawm peb qib, 45, 000 thiab 66, 000 psi feem. Nws yog siv nyob rau hauv daim ntawv thov uas yuav tsum tau lub siab tshaj plaws lub zog thiab durability, xws li offshore roj rigs thiab subsea pipelines.

Qhov zoo:

1. ASTM A252 seamless piling yeeb nkab tuaj yeem tiv taus kev kub siab, kub kub thiab lwm yam kev mob hnyav

2. Siv ASTM A252 seamless piling yeeb nkab yog tus nqi zoo. Seamless kav dej muaj ntau dua cov khoom yuav tsum tau thiab muaj zog durability, uas txo tus nqi ntawm kev tuav steel kav rau cov lag luam.

3. ASTM A252 seamless piling pipes muaj nyob rau hauv ntau qhov ntau thiab tsawg, cov duab thiab cov qauv, ua rau lawv yooj yim rau nruab thiab hloov mus rau ntau qhov kev tsim kho.

Daim ntawv thov:

1. ASTM A252 seamless piling yeeb nkab yog tsuas yog siv nyob rau hauv sib sib zog nqus foundation kev tsim kho ntawm lub tsev, txuas hniav thiab lwm yam loj qauv.

2. ASTM A252 seamless piling yeeb nkab yog siv nyob rau hauv kev tsim kho ntawm offshore roj platforms thiab lwm yam marine lug.

3. ASTM A252 Seamless Piling Yeeb Nkab kuj tseem siv dav hauv kev tsim kho cov chaw nres nkoj thiab cov chaw nres nkoj, thiab hauv kev teeb tsa cov khoom siv hluav taws xob hauv av, xws li cov kav dej thiab cov kav dej.
