Grease Injection Wireline Flow Tubes High Precision For Cable Through

1. How is the flow-tube bore selected?
Provide the measured cable outside diameter and tolerance, including its construction and condition, with the grease-head model and approved drawing. Confirm the required clearance and bore tolerance through the equipment specification.
The listed bore sizes are dimensional references; they do not establish a pressure rating or interchangeability with every head.
2. What dimensions are needed for a replacement?
a. Selected bore diameter and tolerance.
b. Overall length; this listing specifies 14 inches (355.6 mm).
c. Outside diameter and any steps or shoulders.
d. End connections or retaining features shown on the drawing.
e. Bore finish and straightness requirements.
f. Compatible head model and tube arrangement.
g. Drawing revision, part number and required quantity.
3. Does AISI 4145 define the complete material specification?
1. Confirm the ordered grade with material documentation.
2. Specify heat treatment and mechanical requirements where required.
3. Agree the black surface finish and its application limits.
4. Provide fluid, temperature and corrosion conditions for review.
5. Any sour-service or standards-conformity requirement needs specific supporting records.
4. What should be checked before reuse?
1. Bore wear and damage against the approved rejection limits.
2. Outside surfaces and retaining features for damage.
3. Tube identification and compatibility with the head assembly.
4. Cable condition and the specified grease system.
5. Inspection and assembly testing under the equipment manufacturer’s procedure.
 
For grease injection flow-tube enquiries, send the cable details, selected bore, 14-inch length requirement and head drawing. State required material and inspection documents.
Replacement tubes are reviewed against an approved drawing or identified original part; confirm assembly compatibility before use.
