L1 is the approximate length of the precision bore zone of the pipe. The bore of the remaining pipe is not less than the minimum bore of the precision zone. Where the inside diameter of a column must be within closely controlled limits (for example to accommodate sieve plate assemblies), precision bore pipe sections are used.
