Application stages

How This System Helps Reduce Storage Tank Corrosion Risks

Storage tank anti-corrosion risks often come from steel surface preparation quality, weld seams, lap joints, tank bottom plates, bottom-to-wall transitions, nozzle areas, manholes, pipe penetrations, internal corners, immersion exposure, demineralized water contact, oil contact, cleaning cycles, corrosion under deposits, pinholes, lining discontinuity, cathodic disbonding and adhesion failure. This system uses BW8008 cathodic disbonding resistant steel primer before BW3-9512 is applied as the main polyurea anti-corrosion protective lining to help improve adhesion, reduce coating detachment risk and support corrosion protection on prepared steel storage tank interiors.

Steel storage tank surface preparation before anti-corrosion coating
01

Steel Surface Preparation

Steel tank interior should be cleaned, rust-treated and prepared according to project specification before primer application. Oil, dust, loose rust, mill scale, weak coating and contamination should be removed.

Reference: confirm surface profile, rust removal quality, cleanliness, dew point margin and inspection requirement before primer application.
02

Weld Seam and Detail Inspection

Weld seams, lap joints, nozzle areas, manholes, pipe penetrations, tank bottom plates, bottom-to-wall transitions and internal corners should be checked before coating application.

Reference: detail inspection should cover pinhole-prone zones, lining discontinuity risk and areas where corrosion under deposits may start.

BW8008 Steel Primer

Apply BW8008 as the cathodic disbonding resistant steel primer to support adhesion and build the first anti-corrosion interface before BW3-9512 is applied. Without cathodic disbonding resistance, the protective lining may lose adhesion and detach from the steel substrate under service conditions.

Suitable conditions

Suitable Steel Storage Tank Conditions

Use this section to check whether the project fits a BW8008 + BW3-9512 steel storage tank anti-corrosion system before final specification.

  1. 01

    Demineralized Water Tanks

    Prepared steel tank interiors can be reviewed when corrosion protection, immersion exposure and demineralized water contact are part of the service condition.

    Check before specification: stored medium / DFT / inspection

  2. 02

    Oil Storage Tanks

    Oil storage tanks can be reviewed when steel surfaces need primer bonding and a thick-film polyurea anti-corrosion protective lining.

    Check before specification: oil exposure / steel profile / adhesion

  3. 03

    Steel Storage Tanks

    Steel storage tank interiors require project-specific review of surface preparation, stored medium, service temperature and inspection requirements.

    Check before specification: temperature / medium / standard

FAQ

FAQ About Storage Tank Anti-Corrosion Protection

Common questions about using BW8008 and BW3-9512 for demineralized water tanks, oil storage tanks and steel storage tanks.

What is this polyurea storage tank anti-corrosion system used for?

It is used for prepared steel storage tank interiors where demineralized water tanks, oil storage tanks or industrial liquid storage tanks need a polyurea anti-corrosion protective lining.

What role does BW8008 play in this system?

BW8008 is the cathodic disbonding resistant steel primer. It supports metal adhesion and anti-corrosion interface preparation before the BW3-9512 main tank lining is applied. Without cathodic disbonding resistance, the protective lining may lose adhesion and detach from the steel substrate under service conditions.

Which product forms the main tank anti-corrosion lining?

BW3-9512 forms the main polyurea anti-corrosion protective lining over the primed steel tank surface. BW8008 is the primer layer, not the main protective lining.

Can this system be used for demineralized water tanks?

Yes, demineralized water tank projects can be reviewed when the steel surface preparation standard, immersion condition, tank details and project specification are confirmed.

Can this system be used for oil storage tanks?

Yes, oil storage tank projects can be reviewed when the stored oil condition, operating temperature, cleaning cycle, target DFT and inspection requirements are confirmed.

Which tank details need special attention before coating?

Weld seams, lap joints, tank bottom plates, tank walls, nozzle areas, manholes, pipe penetrations, internal corners and bottom-to-wall transitions should be checked before coating application.

What film thickness is recommended for BW3-9512?

BW3-9512 product data lists a film thickness range of 1000-3000 μm and theoretical coverage of 1.12 kg/m2 at 1 mm film thickness. For this demineralized water and oil storage tank anti-corrosion system, BW3-9512 is recommended at about 1.5 mm as the main protective lining. Final thickness should be confirmed according to stored medium, immersion condition and project specification.

What information is needed before specifying the system?

Share the tank type, coating area, steel condition, rust removal or blasting standard, stored medium, operating temperature, target DFT, tank detail condition and inspection standard before final selection.
