The conduit pieces have abutting end faces which engage adjacent pieces in an overlapping fashion with the overlapping being caused by engagement of two layers of staggered conduit pieces of equal length or by complementary step formed end faces of adjacent conduit pieces or by inner diameter or outer diameter radial dimensioned steppings of the abutting conduit pieces with the resultant gaps filled by filler conduit pieces. | |
