Drain plugs for insulation jackets

PPS Drain Plugs with One-Way Silicone Valve

Seamless Integration with LCH Removable Insulation Blankets for Active CUI Prevention

1. Core Technical Features (核心特点)

• Efficient & Unobstructed Drainage (高效顺畅排水)
  Allows trapped condensation and external rainwater tracking to escape freely from within the insulation system, maintaining a bone-dry internal environment.
• Mitigation of CUI Risks (降低 CUI 风险)
  Drastically minimizes the incubation of Corrosion Under Insulation (CUI) by eliminating stagnant electrolyte pools, safeguarding the structural integrity of underlying base metals.
• Industrial-Grade Flame Resistance (工业级耐火材质)
  Precision-manufactured from high-strength engineering Polyphenylsulfone (PPS), which is inherently flame-resistant and non-combustible, fully compliant with rigorous industrial fire safety protocols.
• Direct OEM Blanket Integration (可与保温套一体化集成)
  As a direct source manufacturer, LCH designs and manufactures both the premium removable insulation blankets and the companion drainage systems in-house. This allows the PPS drain plugs to be pre-installed and seamlessly sewn/integrated into the blanket layout prior to delivery, ensuring turnkey field installation.
• Adjustable Thickness Adaptability (厚度自适应与可调设计)
  Features an innovative mechanical profile with an adjustable silicone duckbill valve length. This adjustable architecture enables the assembly to seamlessly fit, telescope, and firmly clamp onto varying blanket thicknesses without creating crushed air gaps or bypassing loose fits.

2. Target Application Fields (应用场景)

• Removable Soft-Cover Insulation Blankets (可拆卸式软质保温套/保温被)
  By embedding this proprietary plug network, plants can significantly extend insulation material service life, drop forced maintenance/teardown frequencies to near zero, and fortify the running reliability of critical insulated manifolds.
• Geometric Low-Points and Condensate Traps (低点等极易积水的物理死角)
  Engineered purposefully for installation at the absolute lowest gravitational bounds within piping loops, chemical towers, and vessel skirts. These zones are high-risk nodes for rainwater tracking and thermal cold-spot condensation; the plug vents fluid immediately before it turns into an aggressive pitting cell.
• Routine Maintenance, Retrofits, and Greenfield Projects (日常检修改造、设备升级以及新建工程)
  The modular structure can be easily retrofitted into pre-existing insulation shells during turnaround maintenance upgrades, or specified directly into new-construction layout blueprints to heavily support corporate Asset Integrity Management Programs (AMP).
