Is seamless tubing always better than welded tubing?

No. The better choice depends on the application, standard, dimensions, tolerance, finish, pressure, documentation and cost. Both routes should be evaluated against the same purchase specification.

What grades are common for seamless capillary tubing?

304, 304L, 316 and 316L are common stainless steel choices. The correct grade depends on corrosion, fabrication, operating environment and customer requirements.

Can seamless capillary tubes be supplied cut to length?

Cut-to-length requirements can be reviewed when the RFQ includes length tolerance, end condition, burr control, bore pass-through, quantity and packing.
