Bolted steel fire suppression tank lining — seam-sealing focused crossover page

Bolted steel tanks have panel joints, bolt lines, penetrations, and gasketed areas that can become leak paths as coatings age or corrosion develops. Fire suppression tanks must remain ready for emergency demand, so seam integrity is critical. Seam sealing helps bridge irregular transitions and supports a more continuous lining surface, reducing the chance of moisture migration and localized corrosion.

PLS 755 Tank Tape is used to bridge gaps, smooth uneven seams, seal transitions around penetrations, and prepare irregular areas before a lining system is installed. AmTech crews hand-apply the tape with firm pressure to activate the adhesive. It is compatible with AmTech lining systems, including DuraChem, HydraStone, Armor Shield, and AT BiFlex.

Seam sealing is usually a preparation and detailing step, not a complete replacement for a protective lining. It addresses specific vulnerability points, such as joints and gaps, while the final lining creates the broader corrosion-resistant barrier. Used together, seam sealing and lining improve continuity, adhesion support, and protection of the tank interior.

Preparation begins with inspection of existing coatings, corrosion, substrate condition, humidity, temperature, and dew point. Depending on the tank condition, crews may use abrasive blasting, wet blasting, hydroblasting, or power tools to remove rust, scale, oxides, and failed coatings. The surface profile is verified before sealing or lining materials are applied.

AmTech selects lining systems based on tank construction, water service conditions, repair scope, and performance requirements. Compatible systems may include HydraStone Alkrete cementitious lining, DuraChem 500 series polylining, Armor Shield coatings, and AT BiFlex fiberglass systems. PLS 755 Tank Tape is designed to be over-coated without typical adhesion conflicts.

Yes. AmTech provides emergency tank repair services for active leaks, corrosion breakthroughs, lining failure, nozzle damage, and unexpected integrity issues. Crews can use temporary sealing materials, structural repairs, and compatible lining systems to stabilize the tank and complete a permanent repair plan when conditions allow.

Project duration depends on tank size, access, condition, corrosion severity, repair needs, environmental controls, and the selected lining system. Some fast-cure lining systems can reduce downtime compared with traditional multi-coat methods. A field assessment helps define the preparation requirements, sealing scope, application schedule, and return-to-service expectations.

AmTech projects are supported by field engineering, experienced crews, and standards-based practices. Work may reference applicable SSPC, NACE, ASTM, API, NFPA, ANSI, NSF, OSHA, and UL-listed system requirements depending on the tank type and service conditions. The goal is safe, durable restoration that supports facility compliance and operational readiness.
