Installation and Maintenance

Installation Guide

Clean pipe threads and Nipple Fig 280 BSPT surface, remove burrs, dust and impurities, ensure compliance with BS EN 10242 installation specifications.
Wrap PTFE tape or apply BS EN standard liquid sealant evenly on both male threads of the hexagon Nipple Fig 280 BSPT.
Screw one end of the Nipple Fig 280 BSPT into the female fitting by hand until preliminarily tightened, avoiding thread misalignment.
Hold the hexagon part with a wrench and tighten steadily and symmetrically, torque meets BS EN standard requirements, avoid excessive force.
After installation, conduct pipeline pressure test at 1.5 times working pressure according to BS EN standard to ensure no leakage.

Maintenance Tips

① Inspection Schedule: Visual inspection quarterly; monthly in corrosive environments, checking coating damage, corrosion, thread damage and leakage.

② Cleaning Method: Wipe the surface with clean soft cloth; do not use sharp tools or strong acid/alkali solvents to damage BS EN standard coating.

③ Replacement Cycle: Replace after 15–20 years of normal use or immediately if thread slipping, sealing failure or serious galvanized coating falling off occurs, ensuring safe operation of BS EN standard system.
