Steel pipes are long and hollow tubes that are used for� many different applications in a variety of places. Such as conveying fluids and powdery solids, exchanging heat, making machine parts and containers and so on. It is also an economical type of steel and� its versatility makes pipes the most often used product that is produced by the steel industry. Steel pipe production technology development began with the rise of the bicycle manufacturing, development of oil in the early years of the 19th century, two world war ships, boilers, aircraft manufacturing, after the second world war thermal power boiler manufacturing, chemical industry and the development of oil and gas drilling and transportation, effectively driving the steel pipe industry in the development of varieties, yield and quality.
