superior qualifications. knowledge and skills.

The aim of every stage of the production process is to achieve total

quality performance. That means producing top-quality pipes and fittings.

During the production process. inspections are applied to ensure quality

control. That includes dimensional inspections, hydrostatic pressure tests.

ultrasonic flaw detector tests. dye-penetrant tests. holiday detector tests.

magnetic thickness tests. tensile tests. radiographic tests. adhesion tests

and bend tests.

In addition. Siam Steel Works promotes ongoing efforts to improve

occupational safety and health. while preserving a clean environment for

all employees and society at large. The company regards the issue of

Whether pipes are used for water supply, irrigation, sewage,

or wastewater projects, protective coatings are crucial to protect

them from corrosion due to aggressive environments such as the

low resistivity of soil, variations in water flow or ground pollution.

The following are the various linings and coating options

available Therefore, Siam Steel Works Co.. Ltd.'s steel pipes and

fittings, are durable and long-lasting.
