폐수 처리장의 일반적인 배관 문제

Common problems include blockages from grease and solids, leakage, hydrogen sulfide corrosion, abrasion, pipe settlement, flange misalignment, pump vibration, pressure surges, gas accumulation and insufficient equipment-removal clearance.

It can help reduce the transmission of some mechanical vibration, but it cannot correct pump misalignment, cavitation, foundation movement, defective equipment or improperly supported piping.

Selection depends on the actual wastewater composition. EPDM may be evaluated for selected water and wastewater services, while NBR may be evaluated for selected mineral-oil media. Chemicals, temperature, solids and exposure conditions must be confirmed.

No. Water hammer and transient pressure require review of pump controls, valve characteristics, check valves, air management, surge equipment and the complete hydraulic system.

They provide controlled installation adjustment and create axial clearance for removing valves, meters and other flanged equipment after the pipeline has been isolated, drained and independently supported.

Provide the medium and solids content, temperature, pressure, possible vacuum, nominal size, actual pipe OD, interface standard, installed length, movement, supports, materials, coating, quantity, drawings and documentation requirements.
