How to check SSAW steel pipe quality from appearance?
SSAW (Spiral Submerged Arc Welded) steel pipe is a type of welded steel pipe produced from strip steel coil. It is extruded at normal temperature and welded using an automatic double-wire, double-sided submerged arc welding process. SSAW pipes are commonly used for fluid transportation, metal structures, and steel pipe piles. A key inspection method for SSAW pipes is appearance quality inspection, which focuses on identifying surface defects on the weld and checking for dimensional deviations.

Carbon steel seamless pipe expansion connection
The expanded connection primarily utilizes malleable cast iron or ductile iron, consisting of key components such as a lined pipe body (bushing), nuts or bolts, threaded rings or expanded pressure flanges, and sealing rubber rings. This connection method uses fastening nuts or pressure flanges to compress the sealing ring. This ensures that the inner surface of the pipe and the sealing ring on the lining pipe are securely connected to the metal pipe fittings, forming a reliable diagonal sealing connection. This article will briefly introduce carbon steel seamless pipe expansion connection.

Mechanical properties of seamless steel pipe
The mechanical properties of seamless steel pipes are critical indicators that ensure their performance in final applications. These properties are influenced by the steel's chemical composition and the applied heat treatment process. In steel pipe standards, depending on the intended use, various mechanical characteristics are specified, including tensile properties (such as tensile strength, yield strength or yield point, and elongation), hardness, toughness, and the material's behavior under high and low temperatures. This article will talk about mechanical properties of seamless steel pipe.
