Seamless electropolished 316L stainless tubing with a smooth controlled bore, square weld-ready ends and protected clean packaging for compatible high-purity gas distribution.
- Electropolished 316L high-purity flow path
- Square ends prepared for controlled orbital welding
- Protected handling from cleaning through installation
Giới thiệu Sản phẩm
High-Purity Gas Tubing forms the clean metallic flow path between gas-source equipment, distribution headers and process tools. The selected catalogue basis is seamless UNS S31603 stainless tube with a 6.35 mm outside diameter, 0.89 mm wall and 0.25 µm Ra maximum electropolished internal surface. Straight 6096 mm lengths reduce unnecessary field joints while square prepared ends support repeatable orbital butt welding. After final cleaning, the bore is dried, both ends are capped and each tube is protected for controlled handling. The product is supplied as unassembled tubing without fittings, valves, regulators, gauges, supports or a fabricated route.
Các tính năng chính
Electropolishing smooths the gas-contact surface and reduces sites that can retain installation residue
Controlled sulfur chemistry options support consistent fusion behavior during qualified orbital welding
Square prepared ends help maintain alignment and a uniform weld gap at tube-to-tube joints
Long straight lengths can reduce the number of field welds needed across a distribution route
Low-carbon stainless metallurgy provides a practical balance of corrosion resistance and weldability
Heat and material traceability can be maintained from received tube through fabricated spool records
Protective caps isolate the cleaned bore during transport, storage and cleanroom staging
Fractional and metric outside diameters support gas sticks, valve boxes, tool hookups and submains
Optional enhanced metallurgy and surface grades allow the tube specification to match more demanding media
Các mối quan tâm về sản phẩm của khách hàng
A clean tube is only one part of a high-purity gas path; material compatibility, received condition, storage, cutting, welding and purge control determine whether the installed line preserves its intended cleanliness.
Open or damaged tube ends can admit particles and ambient moisture before installationKeep the original caps and bags sealed until controlled staging, then inspect and re-cap every cut length immediately.
An incorrect diameter or wall can create unacceptable pressure drop or mechanical marginSize outside diameter and wall from gas demand, route length, pressure, temperature and the governing piping design basis.
Poor end preparation can cause orbital-weld misalignment, oxidation or internal discontinuitiesUse dedicated clean cutting and facing tools, verify squareness and apply a qualified weld and internal-purge procedure.
Mixing heat lots without control can break material traceability across fabricated spoolsTransfer heat identification to cut sections and link each installed spool to its receiving and fabrication records.
A smooth electropolished bore can still be contaminated by dirty tools, gloves or storage racksSegregate UHP fabrication tools and staging areas, use clean handling controls and prevent contact with carbon steel.
Standard 316L may not suit every corrosive, reactive or moisture-sensitive gas conditionReview gas composition, impurities, temperature and upset conditions before selecting metallurgy, finish and joining method.

Thông số kỹ thuật
The selected display basis follows one common Swagelok-class seamless UHP straight tube at 6.35 mm OD x 0.89 mm wall and 6096 mm nominal length, with a 0.25 µm Ra maximum electropolished bore. The site's fixed ten-row schema uses panel-oriented labels; here Panel Thickness identifies the tube wall and Steel Facing Thickness identifies the absence of a separate facing layer. Final pressure, temperature, gas compatibility, cleaning grade, melt route, documentation and weld procedure must match the intended service.
