specific length of the short pipe 110 depends on the material used to make the pipe 110 for example if chromium is added to a u201c mix u201d of steel to strengthen the steel and a short pipe 110 is made from such a mixture an example relationship of pipe lengths may include a short pipe 110 connecting two 25 meter length seamless pipes 107 each having a flange at about three meters from the top of the first lower pipe 107 and connected to the second higher pipe 107 in such an example the relatively short pipe 110 could be 6 meters in length fig1 shows seamless steel pipe 104 containing the steel coil and damper forming the foundation is shown protruding from the ground 100 the crane 103 positions and places a floor forming structure 111 in its folded state on the steel plate 109 with two up facing edges 109 a after the floor forming structure 111 has been stretched by the crane 103 a steel plate 109 u2032 having two down facing edges 109 b and two up facing edges 109 a is placed on the seamless steel pipe 107 held down with a short steel pipe 110 and having another seamless steel pipe 107 inserted into the short steel pipe 110 as depicted in fig1 the steel plate s 109 109 u2032 are shown resting on the flange 108.
