Our pipe lining coating system is a high-performance corrosion protection solution designed for industrial piping. pipelining and coatin. By applying multi-layer organic or inorganic coatings on carbon steel, stainless steel, and alloy steel surfaces, it effectively isolates moisture, oxygen, chemicals, and marine environments, significantly extending pipeline service life. The system covers shop pre-coating, field joint coating, underground protection, and offshore applications, utilizing advanced surface preparation, spray technology, and quality control. We offer complete primer-midcoat-topcoat systems, meeting corrosion protection needs from ambient to high temperature, onshore to deep sea. Widely used in oil & gas, chemical, power, offshore, and municipal sectors.

Common Customer Questions (Q&A Format)
Q: What is the typical service life of pipeline coatings?
A: Heavy-duty coatings last 10–20 years; FBE/3LPE with cathodic protection can exceed 30 years.
Q: How to select the right coating system?
A: Based on environment, temperature, UV exposure, and mechanical risk. We provide expert selection support.
Q: How is coating thickness measured? Do you provide reports?
A: Magnetic gauges measure DFT. We provide test reports per ISO 19840 or SSPC-PA 2.
Q: Do you support field joint coating?
A: Yes, using heat-shrink sleeves, cold-applied tapes, liquid epoxy, or polyurea.
Q: What coating for high-temp pipes (e.g., 200°C+)?
A: Inorganic zinc silicate + high-temp epoxy or ceramic coatings, up to 400°C.
Q: Suitable for food/pharma use?
A: Yes, FDA-approved solvent-free epoxy coatings available.
Q: What is the adhesion requirement? How tested?
A: ≥5MPa (pull-off test, ISO 4624). We test and report per batch.
Q: Do you provide cathodic disbondment testing?
A: Yes, FBE/3LPE tested per SY/T 0414, ISO 21809 for CP compatibility.
Q: What is the lead time?
A: Shop coating: 7–15 days; Field service: On-site teams available globally.
Q: Suitable for subsea pipelines?
A: Yes, FBE+3LPE or dual-layer epoxy systems for subsea use.
