14 Inch Length Wireline Flow Tubes For Grease Injection Control Head

1. Is 14 inches the only dimension needed for replacement?
No. Specify 14 inches (355.6 mm) with its tolerance, then provide outside diameters, shoulders and end or retaining features from the approved drawing.
Include the compatible head model and original tube part number to distinguish parts with the same nominal length.
2. What should be included in the tube drawing?
a. Overall-length datum and tolerance.
b. Bore diameter and tolerance.
c. Outside profile, shoulders and locating surfaces.
d. End geometry and retaining details.
e. Bore finish and straightness requirements.
f. Surface-treatment and marking requirements.
g. Material grade, heat treatment and inspection criteria.
3. How should a set of replacement tubes be ordered?
1. Identify the head model and approved tube arrangement.
2. Separate quantities for each bore or part number.
3. Specify the drawing revision for every configuration.
4. Agree individual part identification and packing labels.
5. Request the material and dimensional records required by the order.
4. What operating information supports the review?
1. Cable construction, actual diameter and condition.
2. Grease system and approved operating procedure.
3. Required assembly pressure, temperature and fluid conditions.
4. Any corrosion or sour-service qualification criteria.
5. Applicable standards and tests with specific acceptance requirements.
 
For 14-inch grease-head flow-tube procurement, provide the complete tube drawing, selected bore, head identification and quantities by part number.
Custom replacement configurations require drawing approval and confirmation of head compatibility before installation.
