ScopeMaterials and ManufacturePermissible Variations in Wall ThicknessPermissible Variations in Outside DiameterHydrostatic TestingMechanical Tests SpecifiedASTM A53 pipe covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding. Continuous-Welded pipe is not intended for flanging. Purpose for which pipe is intended should be stated on order. Looking for specific post-production services? See our full list.HDPE pipe, HDPE pipes, HDPE lined steel pipeHDPE lined steel pipe. HDPE lined steel pipe slightly larger than the outer diameter of tube technology is the main channel diameter HDPE liner, after necking, making cross-section smaller than the cross-sectional area of the main channel, in the role of traction quickly insert the main channel.
ERW is a electric-resistance welded steel pipe, Resistance welded steel pipe is divided into exchange of welded steel pipe and DC welded steel pipe in two forms. AC welding in accordance with different frequencies are divided into low-frequency welding, IF welding, welding
Differences between ERW Steel Pipe and HFW Steel PipeERW 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.
ERW Pipes, HFW Pipe Manufacturer & SupplierThe High-Frequency Longitudinal Seam Welded Steel pipe is also called ERW steel pipe, it's manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.
Permissible Variations for A252 steel piling pipe (1) Wall thickness:Not more than 12.5% under the nominal wall thickness specified. (2) Weights per foot:Each length of pipe pile shall be weighed separately and its weight shall not vary more than 15 % over or 5 % under its theoretical weight, calculated using its length and its weight per unit length.
Electric Resistance Welded Pipe, ERW Steel Pipes, Electric Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
Hfw Steel Pipe - China Hfw Steel Pipe Made-in-ChinaAPI 5L/ASTM A53/JIS G3444 STK290 ERW/HFW Carbon Steel Pipes Round S355J2H Steel Tube,S355Jr Steel Tube,S355 Seamless Steel Pipe For Structure Pipe ASTM A106/ API 5L / ASTM A53 grade b seamless steel pipe for oil and gas pipeline
High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.

Oct 28, 2020 · HFW pipe is widely used in the fields of oil and gas transportation, oil well pipeline, building structure and various kinds of mechanical pipe. However, HFW steel pipe quality is affected by many factors, such as raw material and process. And the production quality control become difficult.ERW/HFW Steel Pipe Galvanized ERW Steel Pipe - Galvanized ERW Steel Pipe Advantage; Galvanized steel pipe features a protective zinc coating that helps prevent corrosion, rust, and the buildup of mineral deposits, thereby extending the pipes lifespan. Galvanized steel pipe is most commonly used in plumbing and other water-supply applications.
