The Relation between the Length and Price of Seamless Steel Oil Pipeline

　　The length of oil pipeline manufacturer is usually 12 meters when producing oil pipe. The length deviation of oil steel pipeline delivered according to fixed length should be within the range of plus or minus 500 millimeters. The production rate of fixed length pipe is much lower than that of normal length oil pipeline, so it is reasonable for the enterprise to raise the price. The range of price increase varies from enterprise to enterprise. Generally, it is about 10% on the basis of base price.

　　The oil pipeline fixed length should be within the normal length range, which is a fixed length size required in the contract. However, API 5CT N80 Seamless Steel Oil Pipeline is impossible to cut the absolute length of fixed length in practice, so the standard stipulates the allowable positive deviation value for the length of fixed length.

　　If there is no length deviation and cutting allowance stipulated in the standard, the supplier and the buyer shall negotiate and specify in the contract. The double-length scale of oil steel pipeline is the same as the fixed-length length scale, which will greatly reduce the rate of finished product. Therefore, it is reasonable for the enterprise to raise the price, and the range of increase is basically the same as that of fixed-length.
