TUBE SECTION HAVING SLOTS FOR SAMPLING

摘要

A pair of elongated cylindrical members are constructed with first and second collars extending axially beyond their adjoining ends. The first and second collars have adjoining indentations and projections at their end edges which are adapted to interlock with one another so as to prevent rotation of the two elongated members with respect to one another. A coupler is removably fitted over the exterior of the first and second collars and holds them together against axial movement with respect to one another. The collars are each welded to the axial ends of the first and second cylindrical members. A sampling tube section is provided having slots to allow the fluid to be sampled to enter the internal bore of the tube. The slots are axial, and are spaced apart both angularly and axially. The slots are tapered so as to have a narrower width at the outer surface of the tube than at the inner surface of the bore.
