Industry Knowledge

Stay informed with technical insights and best practices

Seamless vs Welded Pipe

Seamless pipes are formed without a weld seam, offering higher pressure resistance. Welded (ERW) pipes are cost-effective and suitable for lower-pressure applications.

Inconel vs Stainless Steel

Inconel offers superior performance in high-temperature and corrosive environments, while stainless steel is ideal for general corrosion resistance and cost efficiency.

ASME B16.5 Flange Dimensions

Standard covers pressure-temperature ratings, dimensions, and tolerances for pipe flanges and flanged fittings from Class 150 to 2500.
