potassic volcanic rock best known for sometimes containing diamonds
pipe schedule is an American definition to define pipe thickness and how much pressure can the pipe stand, schedules are 10,20,40,80.., pipe schedule is nearly close to the eurobian definition for pipe class.
Black pipe is an amateur term for common steel or iron pipe.

If you are asking what is the spring line of a pipe, it is the point of greatest horizontal dimension when looking at an end cross section of a pipe.
Kimberlite is what yellow ground is.Specifically, the term designates the impact of limonite on the weathered expression of this igneous rock. Kimberlite is an important diamond source. It owes its name to the discovery of its diamond-containing deposits near Kimberley, South Africa.
Trucks typically access the bottom of a kimberlite pipe by following a spiral ramp or a series of switchbacks that lead downwards from the surface to the bottom of the pipe. This ramp is carefully engineered to accommodate the size and weight of the trucks and is often used during the mining process for various operations and transportation of materials.
Diamonds are found as loose stones, or can be embedded in other materials, including kimberlite. See the linked photo, below.
You can find a map of kimberlite pipes in the USA through geological surveys or research institutions that specialize in diamond exploration and mining. These organizations may have publicly available maps or data on kimberlite pipe locations.
Kimberlite is the natural structure within which diamonds are found (kimberlite "pipe"). A Kimberlite pipe is the normal underground site(s) of a diamond bearing geologic formation.Another AnswerKimberlite is a mineral, called a trace mineral, because in one out of 200 cases, when kimberlite is found, diamonds are also found. Why? Because the geological processes required to form diamonds also forms kimberlite, which is a 'potassic volcanic rock' according to Wikipedia.

Natural diamonds from the Earth originate in kimberlite pipes, and can be swept away by water or glaciers. This means that some diamonds are found in river beds and at the mouths of rivers as they empty into salt water.
A craton is 'an old and stable part of the lithosphere' -- the earth's crust. One class of inclusions in the formation of the earth's crust when subductions of crust were folded into the deep, kimberlite diamond areas that lie about 150-450 K below the surface. Diamonds as we know them are exploded to the earth's surface through kimberlite pipes, which are carrot shaped and widest at the surface. Although not all kimberlite pipes are sources for diamonds, most diamonds are found in areas where kimberlite pipes occur.
All diamonds are formed from carbon. Kimberlite and diamonds are both erupted to the earth's surface via volcanic pipes. Kimberlite is an indicator mineral, increasing odds for geologists that a volcanic pipe includes diamonds: not all pipes erupt diamonds with kimberlite. Kimberlite can be considered a 'neighbor' or 'kin' of diamond, but not a source.
Yes, kimberlite does react to acid. The carbonate minerals in kimberlite can fizz or effervesce when they come into contact with acid, indicating a chemical reaction. This reaction is due to the dissolution of the carbonate minerals in the kimberlite by the acid.
