Instrument tubing is widely used in industries of medicine,
car and train oil piping system, pneumatic cylinder, microelectronics
aerospace and semiconductor, with strict requirements
on inner clean and smooth.
We could supply two kinds of stainless steel instrument tubinigs, one is with outside polishing after annealed and pickled, and the other one is briht annealed. The formerr one is about 1/3 cheaper, and delivery time could also be shorter.
The order is one of the regular repeat order from this customer, it contains TP316/L and TP304/L dual grade material, which means that the supplied materials have to fulfill both TP316(TP304) and TP316L(TP304L) quality on both chemical composition and michanical properties. At same time the materials are A269 and A213 dual certified, which means that inspections as size torlerance, NDT, Michanical Tests ... have to meet requirements in both specifications.
The sizes of the order ranges from 1/4" to 2", tubes are all 20' fixed length. It takes us about 50days to produce these tubes(12tons), small tubing takes longer time to produce because there are much more proceses, and the polishing, inspection, marking, and hydraulic test for small tubing is also time consuming.
