STS Lining

Product Overview

Stainless Steel Lining is a Technology to line the Inner wall of a Concrete Structure that is in Direct Contact with Water in Relation to a Water Purification Plant, Sedimentation Pond, Filter Paper, Water Purification Pond, Reservoir, etc., or a Concrete Water Storage tank of a General Building, with Molded Stainless Steel Panels It is an Eco-friendly Technology that Blocks Leaks and Fatigue caused by Hardening,Extends the Life of Structures, and Secures Hygieneand the Environment.

Necessity of Lining

Threats to Public Health and Safety Caused by Contamination of Stored Water
  • High Maintenance Cost because of Frequent Defects and Continuous Maintenance
  • Low Economic Feasibility Leading to Leaks and loss of Water Resources
  • Heavy Pollution | Short Life and Dirty Floor

  • Film Peeling | Leaks and Coating Marks

  • Heavy Pollution | Dirty Floor

  • Heavy Pollution | Epoxy-contaminated Water

Corrosion Resistance

By Applying Duplex Stainless Steel (STS329LD, STS329J3L), it has Excellent Corrosion Resistance to Chlorine Ions to Prevent Oxidative Corrosion and Enable Permanent Use.

    High Corrosion Resistance Stainless Steel (STS329J3L, STS329LD)

    • The Duplex Stainless Steel Material is Waterproof and Durable.
      It has Corrosion Resistance Against Internal Chlorine Ions.
      Through this, Only Regular Maintenance can make the Sanitation of the Storage Water Permanent.

    Corrosion Resistance to Chlorine Ions

    • Statistical Data on Water Quality in Seoul and Busan Purification Ponds : Residual Chlorine Amount 0.6–1.2 ppm
    • Experiment Conditions (1 year and 2 months)
    • Residual Chlorine Content in Water Quality 0.8–1.2 ppm | Material STS304 / STS316L / STS329L

3D Scanner

Accurate Measurement without Error using 3D Laser Scanner

    Securing Design Reliability through Accurate Quantity Calculation

    • Short / Medium / Long Distance Precision Scan with Laser Broadband Scanner
    • Possible to Scan most Precisely Among Devices in its Class - Can Scan up to 140m with One Scan
    • Convenient Drawing by Interlocking with AutoCAD - Possible to work with Actual Standard

    AUTO CAD Linked Picture

    • AUTO CAD Modeling Pictures

    Through 3D Surface Flatness Scan Photos

    • Possible to Review the Flatness and Uneven Structure of a Specific Area
    • Suggestion of a dew Condensation Section and Structure Improvement Guide

STS Lining Structure

  • | High Corrosion Resistance
  • Lining Technology of Moonchang Co., Ltd. that Applied Duplex Stainless Steel (STS329LD, STS329J3L) Material as a Panel
  • | Domestic Original Patent
  • It Possesses Stainless Steel Lining Technology (Registered in 2002) and has the Highest Performance in Korea with Moonchang Co., Ltd.’s Expertise and Technology

STS Lining Patents Baffle Walls

Water Tank with Built-in Water Flow Guide Board | Patent No. 10-1140762
By Manufacturing and Installing a Water Flow Guide Plate without a Separate Concrete Structure, it Shortens the Stagnation of Water and Increases the Disinfection and Sterilization Effect by Increasing the Chlorine Contact Time.

  • Forcibly Generating Water Flow through the Circulation Guide Plate
  • A First-in-first-out Structure is created to Reduce the Residence Time of Water → Prevention of Microbial Propagation and Contamination
