MATCH THE TUBE TO THE COMPONENT
The right detail
for your tube.
Gas-lift designs can include outer, inner and intermediate tubes. The required material and geometry depend on the individual component drawing.
- Tube position and required welded construction
- Material grade, standard and delivery condition
- OD, ID or wall thickness, roundness and straightness
- Internal surface, length, ends and inspection requirements
FROM TUBE TO COMPONENT
Define the finishing route.
Combine the tube specification with the operations required for your part.
Dimensions & runout
Define the OD, ID or wall tolerance, straightness and part inspection criteria.
Surface & cleaning
Include the required surface condition, cleanliness and product protection.

Useful product details.
Are these welded or seamless tubes?
The sizes on this page are cold-drawn welded tubes. Welded mother tubes are subsequently cold drawn; this does not make them seamless.
Does each size correspond to a particular inner or outer tube?
Use your component drawing to define the tube position. The production table lists material and dimensions without assigning individual sizes to inner, outer or intermediate tubes.
Are the listed sizes stock items?
The table gives regular production examples. Send your required length, quantity and delivery condition to discuss a quotation.
Can I request a different grade or size?
Yes. Send your required grade, size and application. DOM will review the appropriate product route and requirements.
