Product Description

Spiral Pipe itself does not get hot, but the experimental samples will be significant fever. When the heating temperature exceeds the arc melting machine, radio frequency sensors will provide more control, so that scientists can adjust the alloy of specific composition ratio. Spiral Strong pressure steel, plastic, and easy welding and machining molding; general low pressure liquid delivery spiral submerged arc spiral Steel Pipe (SY5037-83), using double-sided or single-sided automatic submerged arc welded into the legal system for water, gas, air and steam.
