Manufacturing and production standard of wear resistant Dalian compressed air pipeline

There are strict manufacturing and production standards for wear-resistant pipes, and the manufacturing standards affect the price of wear-resistant pipes. When comparing the prices of wear-resistant pipes, the same manufacturing and production standards for wear-resistant pipes must be formulated first, so that the prices of wear-resistant pipes made under the same standards can be compared.

The wear-resistant pipeline of Dalian compressed air pipeline is connected with our pipeline by welding. The elbow has material transition at the interface, and the bidder is responsible for the transition from the interface pipe to our straight pipe section Ф five hundred and eighty × 10 mm, made of Q235 steel. Both ends of the wear-resistant pipe shall be sealed with rubber rain cover to avoid internal humidity.

The operation risk of Dalian compressed air pipeline is small and the safety factor is large, so it will not cause major accidents due to failure. The operation is stable, and there is no or little leakage, emission, dripping and leakage, so as not to cause shutdown or frequent shutdown of the unit in a short production cycle. During the design, the safety problems that may occur shall be correctly evaluated, and full consideration shall be given to the arrangement of wear-resistant pipes and pipeline equipment to reduce the probability of accidents.

The technology of centrifugal casting composite ceramic pipe of Dalian compressed air pipeline determines that it is not suitable for making pipe fittings and large and small heads. Under ordinary technical conditions, composite ceramic pipes can only be made into straight pipes. To make elbows or large and small heads, the straight pipes must be divided into several sections for welding. The inner wall of the formed pipe fittings and large and small heads is not of streamlined structure, which hinders material transportation and reduces equipment output.
