Functional Features
Tight Sealing
The pipe ends are precision processed. When matched with high-quality sealing components, the pipeline connections remain fully sealed and leak-free.
Easy Machinability
The pipe possesses good cutting and welding performance and can be flexibly reprocessed to meet various engineering requirements.
Long Service Life
Thanks to its superior overall performance, its service life is far longer than that of ordinary carbon steel and alloy pipes under normal operating conditions.
Usage Instructions
Pre-installation Inspection
Before installation, thoroughly inspect the appearance and dimensions of Large Diameter Stainless Steel Pipe to confirm no damage or deformation and full compliance with design requirements.
Standard Cutting
Use dedicated cutting tools for sizing. Keep cuts flat and burr-free to avoid affecting subsequent welding quality.
Standard Welding
Select matching welding materials and technical parameters during welding, and take sufficient protective measures to ensure qualified weld seams.
Bracket Fixation
Install proper supports and fixing points for pipelines to prevent deformation and displacement caused by thermal expansion and contraction.
Pressure Test
Conduct a pressure test after installation is completed. Do not put the pipeline system into formal operation until no leakage is confirmed.
Maintenance Guidelines
Clean the outer surface of the pipe regularly to remove dust and dirt for easier inspection and maintenance.
Inspect the pipe surface periodically. Promptly handle local corrosion once found to prevent further spread.
Regularly check the tightness of pipeline connections. Retighten loose components in a timely manner to maintain reliable sealing.
Regularly operate valves and other pipeline accessories and apply lubrication to ensure normal functions.
Entrust professional teams to conduct regular maintenance and testing with professional equipment, so as to guarantee long-term stable operation of the pipeline system.
