Storage Conditions

Proper storage ensures the longevity and performance of WCB stainless steel components before installation:

1. Environmental Control

• Store in a dry, ventilated warehouse to prevent moisture accumulation.

• Avoid exposure to corrosive chemicals or salt-laden air.

• Maintain stable temperature conditions to reduce thermal stress.

2. Handling Guidelines

• Use lifting equipment to avoid mechanical damage.

• Avoid dropping, scratching, or impacting surfaces.

• Store horizontally on wooden or rubber supports to prevent bending or warping.

3. Protective Measures

• Apply anti-corrosion coating or oil if storage exceeds 3 months.

• Cover with dust-proof and moisture-proof materials.

• Inspect regularly for signs of rust, corrosion, or surface defects.

Fault Repair and Maintenance

WCB stainless steel components are durable, but occasional faults or wear may occur. Proper repair and maintenance prolong service life.

1. Common Faults

2. Maintenance Guidelines

• Conduct regular inspections for surface integrity and signs of corrosion.

• Keep mechanical joints, flanges, and threaded connections clean and lubricated.

• Apply passivation or anti-corrosion treatments periodically.

• Monitor operating temperatures and pressures to avoid overstressing components.

3. Repair Techniques

• Welding and overlaying: For minor cracks or worn surfaces, use compatible stainless steel filler material.

• Machining: Restore dimensional tolerances for flanges, valve seats, and pump components.

• Surface treatments: Polishing, passivation, or coating to restore corrosion resistance.
