Chemical Requirements for A53. Lengths of A53 steel pipe U. S. Steel Tubular Products A53 seamless and welded steel pipe is produced in random lengths 16’ – 22’ or 32’ – 44’, in multiple lengths, and in specific cut lengths.
Differences between ERW and HFW Steel Pipe. ERW pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is specially for high frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin wall thickness steel pipes.

ERW steel pipe is the abbreviation of electric resistance welding steel pipe, we can produce API 5L, ASTM A53 differenent materials erw steel pipe and erw casing.
Advantages of ERW pipe. High efficiency, low cost, material saving, easy automation. What is HFW steel pipe? It shall be noted that HFW pipe is a type of ERW pipe. High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ.

Aug 05, 2015 · ASTM A53 Grade A Carbon Steel Seamless Pipes are Low Carbon Steel Pipes with 0.25 % carbon content with combination of 0.95 % manganese. These Pipes are also known as mild steel pipes and tubes. ASTM A53 Grade A Pipes are low cost Pipes easy to form and shape.
Common sizes for ERW Steel Pipe range from 2 3/8 inch OD to 24 inch OD in a variety of lengths to over 100 feet. Surface finishes are available in bare and coated formats and processing can be handled on site to customer specifications.
SSG High frequency longitudinally welded pipe production line is mainly used for the production of welded steel pipe of φ8 ~ φ610 mm and wall thickness of 0.5~ 20mm as well as the production of square, rectangular, and other custom seamless pipe profile, Carbon steel pipe, ERW steel Tube.
ASTM 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.
This Standard specification for pipe, steel, black and hot dipped, zinc coated, welded and seamless. ASTM A53 is always required with large quantities from different industries, and it includes three types in pipeline systemaSeamless type. bWelded Type (ERW, EFW, HFW, SAW) c
ASTM A53 pipe is sized according to the nominal pipe size (NPS) system. Tianjin Huilitong Steel Pipe Provides a full range of ASTM A53 Pipe inRound Pipe Sizeoutside diameter 88.9 457mm, thickness 2.5 16mm of ERW Pipe
High frequency Induction Welding Technology is used for ERW Pipes &Tubes upto 21 inchesOD. How to Identify Seamless or ERW Stainless Steel pipes? To identify that a pipe supplied is seamless or ERW, Simply read the stencil on the side of the pipe. If it is ASTM A53, Type S means seamless. Type F is furnace but welded, Type E is Electrical
The most common pipe piling material is ASTM A252 Grade 3 pipe, this pipe grade could be made in seamless or welded, which in most situations are requested in welded type because of the large diameters pipe pile required. A252 Grade 3 has better strength which tensile in 455 Mpa (66,000 psi), and yield strength 310 Mpa (45,000 psi).
High frequency welding for carbon steel welded pipe production has been 40 years of history. High frequency welding power power of different material, diameter and wall thickness of steel pipe to achieve a higher welding speed (more than l0 times higher than the the TIG highest welding speed).
And we mainly supply HFW (High frequency welding) pipe in advanced technology. The weld seam of HFW pipe is heat treated after welding that no untempered martensite remains. And the weld flash can be removed from both inner and outer surfaces. We provide welded steel pipe as standardASTM A53 Pipe, Steel, Black and Hot Dipped, Zinc Coated, Welded
In case ASTM A53 Grade B in ERW (electric resistance welded) pipe, the weld seam shall be done the heat treatment with a minimum 1000°F [540°C]. In this way the no untempered martensite remains. In case ASTM A53 B pipe in cold expanded, then expansion should not exceed 1.5% of the required OD.
