Conveying pipe for concrete pump truck
The invention discloses a conveying pipe for a concrete pump truck, and the manufacturing technology of the conveying pipe is simple. The conveying pipe for the concrete pump truck comprises a pipe body and a pair of installation flanges arranged at the two ends of the pipe body in a sleeving mode; the pipe body is a seamless steel pipe; the seamless steel pipe comprises the following components of, by weight percent, 0.6-0.65% of carbon, 0.75-1.00% of manganese, 0.2-0.35% of silicon, 0.25-0.75% of chromium, 0.01-0.05% of titanium, 0.1-0.25% of copper, no larger than 0.02% of phosphorus, no larger than 0.15% of sulphur, no larger than 0.2% of nickel and the balance iron. The conveying pipe provided by the invention is resistant to abrasion, has enough toughness and hardness and is especially suitable for being made into conveying pipes for the concrete pump truck.
本发明公开了一种制作工艺较为简单的混凝土泵车用输送管，包括：管体以及一对套设在管体两端的安装法兰，所述的管体为无缝钢管，按重量百分比计，所述的无缝钢管包括以下成分：0.6～0.65％的碳、0.75～1.00％的锰、0.2～0.35％的硅、0.25～0.75％的铬、0.01～0.05％的钛、0.1～0.25％的铜、以及不大于0.02％的磷、不大于0.15％的硫、不大于0.2％的镍，余量为铁。本发明所述的输送管，既耐磨又具有足够的韧性和硬度，尤其适用于制作混凝土泵车用输送管。
