Stainless Steel Pipe Production Process :

This image illustrates the complete seamless pipe production process, consisting of eight key stages: raw material preparation, lubrication, annealing, surface grinding, acid cleaning, cold drawing, ultrasonic testing, and final packaging. Each step is carefully controlled to ensure high dimensional accuracy, excellent surface finish, and internal quality, meeting the stringent requirements of industrial applications.

304 Stainless Steel Pipe Roughness test :

At SAKY STEEL we perform strict roughness testing on stainless steel pipes to ensure a smooth and consistent surface that meets international standards. Pipe roughness is a key factor that affects flow efficiency corrosion resistance and overall performance in critical applications. We use precision instruments to measure surface roughness values ensuring all pipes meet customer requirements for smoothness and finish. Our pipes are ideal for chemical food processing marine and structural industries where surface quality is essential.  

Stainless Steel Pipe Surface Test:

The surface finish of stainless steel pipes is critical for performance and appearance. At SAKY STEEL we strictly control surface quality through advanced inspection processes. The image shows a clear comparison between bad surface pipes with visible defects and our good surface pipes with smooth and uniform finish.

Our stainless steel pipes are free from cracks pits scratches and welding marks ensuring excellent corrosion resistance and reliability. These pipes are widely used in chemical marine and structural applications where surface integrity matters.

 

PT Test :

 SAKY STEEL performs penetrant testing PT on stainless steel pipes and components as part of our strict quality control process. PT is a non destructive testing method used to detect surface defects such as cracks porosity and inclusions that are not visible to the naked eye.

Our trained inspectors apply high quality penetrant and developer materials to ensure accurate and reliable results. All PT procedures follow international standards and customer specifications guaranteeing product safety and performance.
