Ubwiza Bwiza Ubushinwa Bishyushye DIP Sch40 A53 API 5L Gr. B Ikidodo / Ikizunguruka kizunguruka / ERW / Umuyoboro wa Carbone Umuyoboro
Incamake
Tuzakora ibishoboka byose kugirango umuntu abe indashyikirwa kandi adasanzwe, kandi yihutishe intambwe zacu zo guhagarara imbere yurwego rwisi yose yo mu rwego rwo hejuru ndetse n’ikoranabuhanga rikomeye kuri A53 Gr. B Umuyoboro wa Carbone Steel / Welded, Turakwishimiye gusura uruganda rwacu kandi dutegereje kuzashyiraho umubano wubucuti nabakiriya murugo ndetse no mumahanga mugihe cya vuba. Ibicuruzwa byacu byose nibisubizo byujuje ubuziranenge mpuzamahanga kandi birashimwa cyane kumasoko atandukanye kwisi. Niba ushishikajwe nibicuruzwa byacu cyangwa ukaba wifuza kuganira kubitumenyetso byabigenewe, ibuka kutumva neza. Twategereje gushiraho umubano mwiza mubucuruzi nabakiriya bashya mugihe cya vuba.
ASTM A53 igaragaza ibisabwa kugirango umuyoboro wumukara utagira ikidodo / weld wirabura kandi ushyushye-ushyizwemo ibyuma byifashishwa muri rusange. Ibyuma byashyizwe ku rutonde bigomba gutunganyirizwa mu itanura rifunguye, ogisijeni ya alkaline cyangwa itanura ry’amashanyarazi, kandi bigomba kuba bifite imiti ikurikira: karubone, manganese, fosifore, sulfure, umuringa, nikel, chromium, molybdenum na vanadium. Umuyoboro ugomba kuba udafite kashe cyangwa gusudira. Ibizamini bya Tensile, kunama no gusibanganya bigomba gukorwa kugirango harebwe niba bigomba kuba byujuje ubuziranenge busanzwe. Ikizamini cya hydrostatike kigomba gukorwa, kandi ntagisohoka mumubiri weld cyangwa umuyoboro. Ibizamini by'amashanyarazi bidasenya bigomba gukorwa kugirango ubwinshi bwumuyoboro bugomba kuba bujuje ubuziranenge. Niba bibaye ngombwa kwemeza ko umuyoboro wujuje ibyangombwa bisabwa, umuguzi afite uburenganzira bwo gukora igenzura n’ibizamini byavuzwe muri iki cyerekezo.
ASTM A 53 ikwiranye na sisitemu yo kuvoma igitutu, imiyoboro y'imiyoboro hamwe n'imiyoboro rusange igamije ubushyuhe bwa dogere 350. Muri byo, icyiciro cya Gr.B nicyuma gikoreshwa cyane, hamwe nimbaraga zacyo zingana ≥ 415 (MPa) kandi zitanga imbaraga ≥ 240 (MPa).
Gusaba
Irakoreshwa Cyane kubice byingufu nigitutu, no mubikorwa rusange ibyuka, amazi, gaze numuyoboro wikirere.
