The Relation between the Length and Price of Oil Pipe

　　API 5CT J55 Seamless Steel Oil Pipe fixed length should be within the normal length range, which is a fixed length size required in the contract. However, oil pipe 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 pipe 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.
