Differences between ERW Steel Pipe and HFW Steel Pipe

ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond. Meanwhile with the combined pressure, the edge of the pipe Difference Between Seamless and Welded/ERW PipesPerformance and Usage: Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the What's the Difference Between ERW Pipes and Seamless Pipes?The reliability of the pipes is guaranteed by leakage testing of the steel cylinders under pressure and the excellent quality of the concrete used in their production. This method allows the production of pipes from DN 500 to 4000 mm with lengths of up to 8 metres.

ASTM A252 covers nominal wall cylindrical steel pipe piles in which the steel cylinder acts as a permanent load-carrying member or as a shell to form cast-in-place concrete piles. ASTM A672 covers electrical-fusion-welded steel pipe for high-pressure service at moderate temperatures.Why to use ERW Pipes? What are applications ? - HYSP , erw high pressure concrete pipeERW pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished ERW pipes. Advantages : As only the edges are heated, the tube possesses dean accurate surface. Applications : (i) Electric resistance welding can make tubes in sizes up to 0.4 metre diameter.Difference between Seamless & ERW Stainless Steel pipeWhat is the Difference Between Seamless and ERW Stainless Steel Pipes? Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section

Steel Pipes : Materials of Construction » The Piping , erw high pressure concrete pipe

Selection of Material of Construction for steel pipes depends on their Design Temperature, and Fluid Properties. Pipes made from carbon steel lose strength at high temperatures. Electric-resistance-welded pipe is not considered satisfactory for service above 750 F, whereas furnace-buttwelded pipes are not good above 650 F. For higher temperatures, pipe made from stainless steels or []Reinforced Concrete Pressure Pipe (RCPP)Pipe size range: 1000mm to 4000mm diameter; Can be designed for high pressure applications and for external loads. Wide range of fittings; Applications: Sub aqueous pipeline, gravity sewers, culverts, irrigation, water supply, storm drains, water distribution and Precast Concrete Pipe DurabilityNormally, concrete pipe is not exposed to this combined set of con-ditions. When it has been, however, its performance has been excellent, primarily due to the high density and quality of the concrete.
