carbon steel pipe introduction

An introduction to carbon steel pipe

 

Carbon steel pipe perforation made of steel ingot or solid tube capillary, and then dial made by the hot-rolled, cold rolled or cold. Carbon steel pipe has an important position in China's steel industry.

According to incomplete statistics, China's existing carbon steel pipe production enterprises is about 240 more than the carbon steel pipe mill about more than 250 sets of annual production capacity of more than 450 million tons. See from the caliber <φ76, accounting for 35% <φ159-650, accounting for 25%. From a variety of general purpose of the 1.9 million tons, accounting for 54%; oil pipe 760,000 tons, accounting for 5.7%; hydraulic prop, precision tube 15 million tons, accounting for 4.3%; stainless steel pipe, tube bearings, automotive tube for a total of 50 000 tons, accounting for 1.4%. ?

The raw materials of carbon steel pipe is a round tube, the tube embryo billet cutting machine cutting the growth of the degree of approximately 1 meter and sent by conveyor belt furnace heating. Billet is fed into the heating furnace, the temperature is about 1200 degrees Celsius. Fuel for a hydrogen or acetylene. The furnace temperature control is critical to wear air tube round, after the release of pressure puncher. Are generally more common puncher tapered roller punch this punch, high production efficiency, product quality, perforated expanding volume, wearing a variety of steels. After perforation, round tube has been three-roll cross rolling, rolling or extrusion. After extrusion off pipe sizing. Sizing mill by the high-speed rotation of the cone drill into the Billet punch to form a steel pipe. The steel pipe inner diameter is determined by the length of the outer diameter of the sizing mill drill. After sizing, the steel pipe to enter the cooling tower by the water spray cooling, the steel pipe after cooling, it is necessary to be straightening. Sent by conveyor pipe by straightening the metal detection machine (or hydrostatic test) to conduct an internal flaw. Steel pipe internal issues such as cracks, bubbles will be detected. Steel pipe quality inspection but also through a rigorous manual selection. Steel pipe of Quality Supervision, Inspection, use spray paint on the number, size, production batch. By a cable car hanging into the warehouse. carbon steel pipes -
