Stainless Steel Pipes

Super Duplex stainless like S32750,is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic

Stainless steel 347 is variation of fundamental austenitic 18/8 Grade 304 with included Columbium.Superior general corrosion resistance over Type 321

ERW-Electric Resistance Welded
EFSW- Electric Fusion Spiral Welded
SAW-Submerged Arc Welded
SSAW-Spiral Seam Arc Welded

All stainless pipe is supplied as dual certified (material can be used for both straight-grade and low-carbon requirements).

Electric Fusion Welded pipe is formed by rolling plate and welding the seam. Pipe is manufactured to one of several international industrial standards

Austenitic stainless steel have a very wide range of applications, e.g. in the chemical industry and the food processing industry.

PMI Testing, Chemical Analysising, Mechanical Experiments, Ultrasonic Testing, Eddy Current Testing, Hydraulic test, Hydrostatic Testing,

Also known as UNS S30400, these 304 Stainless Steel Pipes has some great features like it is non magnetic, can be easily welded, having high ductility

Stainless Steel 304 is a balanced austentic Steel which is widely applied and versatile in wide spectrum of products, finishes and forgings.

Type 304-the most common grade;the classic 18/8(18% chromium, 8% nickel) stainless steel. Outside of the US it is commonly known as A2 stainless steel

Tubes and Pipes can be used interchangeably and generally refers to a cross section hollow structures, most commonly cylindrical
