After a long enough time, the rate of steel pipe manufacturing tends to decline exponentially. The pressure dependent coefficient can be used to describe the diffusion of black steel pipe pressure in terms of hydraulic diffusivity. Physically, it is unrelated to the molecular diffusion coefficients of the steel pipe. However, the more closely spaced the fractures are, the higher will be the initial rate of black steel pipe.

At the same time, the interference time will be reached in a more rapid manner. These intuitive considerations are consistent with the mathematical results concerning black steel pipe and with specific analysis. Hydraulic fracture in black steel pipe creates a network of cracks and it might be previously impermeable in steel pipe manufacturing. The true geometry of a large scale steel pipe system is very complicated so we need to explore the possibility to treat the rock surrounding. What is more, permeability can be greatly enhanced over the surrounding area as long as we focus first on the single region.

The solution of a problem can be obtained trivially by multiplication of black steel pipe once the problem is bounded by a pair of fractures. For comparison of matrix microstructure with steel microstructure, a range of engineers have devoted to design of advanced black steel pipe. The relative high Si concentration can be used to prevent precipitation and some amount of Ni, V and Cr can strengthen the pipe structure. The temperature of isothermal quenching may vary so that black steel pipe can exhibit high strength so as to produce fine grain structures. In those studies commercial grade black steel pipe can be treated for one hour and then isothermally quenched.

The temperature and time of quenching are different depending on the microstructure of black steel pipe we would like to produce. For instance, if we decide to compare black steel pipes from point of view of their structures, scanning electron microscopy and transmission electron microscopy can be employed. On the other hand, if we intend to experiment with black steel pipe that is used to transfer gases, we should firstly allow methane and other hydrocarbon gases to migrate to the production well.

The well and formation of black steel pipe are partially cleared of liquids after which the well is placed into production. Production of black steel pipe is projected to grow to more than fifty percent by 2040. The total absolute black steel pipe stocks have grown dramatically throughout the 20th century so that the average steel pipe prices are on the decrease. At the same time, steel pipe manufacturing has been continuously improved and upgraded to offer higher quality pipes.
