Surface Treatment of HFW Steel Pipe

 

1D / 1E – Hot Rolled Plate

Hot rolled, softened (annealed) with the surface de-scaled. The surface remains rough and heavily pitted and subsequent finishing is limited to heavy grinding. It can be used where uniformity and smoothness of finish are not important and where a heavy ground surface is acceptable.

2D

This material is cold rolled followed by softening and de-scaling. The effect of cold rolling the material is to produce a smoother, less pitted surface. The surface is not only smooth but of matt grain appearance. Used where a better surface is required or subsequent processing/ finishing is necessary.

2B

The material is cold rolled, softened and de-scaled as in the case of the 2D finish and then receives a final light pass on polished rolls called a 'skin pass' or 'pinch pass'. The material remains grey in appearance but the effect of this final pass on polished rolls is to produce a smoother, brighter surface than the 2D finish. This is the general purpose, cold rolled finish and it is suitable for a wide range of applications where stainless steel pipe is specified. It is also suitable for a wide range of subsequent polishing processes such as satin finishing.

2R (Bright Annealed)

This finish is also produced by cold rolling and de-scaling but in this case the final annealing is done in a controlled atmosphere furnace. The effect of annealing without the presence of oxygen is to produce a reflective surface on the stainless steel pipe and it is often used in preference to a 2B finish where reflectivity is important, such as catering equipment. The very smooth surface also makes this surface highly suitable for further finishing processes such as mirror polishing and chrome plating.

 

Cutting HFW Steel Pipe Thickness and Diameter

 

1.Thin Pipes:

Hacksaws, reciprocating saws, and steel pipe cutters are suitable for thin-walled pipes. These tools provide adequate precision and control for smaller dimensions.

2.Thick Pipes:

For thicker pipes, robust tools like band saws, circular saws, or laser cutters are recommended. These tools can handle the increased material thickness and provide cleaner cuts.

Welding Style of HFW Steel Pipe
 

High-Frequency Welding :
High-Frequency Welding(HFW), is one of the primary methods utilized in ERW pipe manufacturing. It includes passing a high-frequency current through the edges of the steel strip, triggering them to heat and melt. Once the edges are in a molten state, they are pressed together to form a bond. The resulting weld is characterized by its strong joint and relatively very little heat-affected zone.

 

Contact Welding:
Contact welding is a strategy that includes applying pressure to the edges of the steel strip and concurrently passing an electrical current through them to create the weld. This method is frequently utilized in the production of ERW pipes with smaller sizes. In contact welding, the pressure used plays a significant role in attaining a proper bond in between the edges.

 

Induction Welding:
Induction welding is another method used in ERW pipe manufacturing. This strategy utilizes the concept of electromagnetic induction to warm the edges of the steel strip. A rotating current is travelled through a coil, generating a magnetic field that causes eddy currents in the strip, triggering it to heat up and subsequently weld. Induction welding uses the advantage of exact heat control, which can help reduce the heat-affected zone and avoid extreme material distortion. It is particularly useful for producing pipelines with thinner walls and diameters.

 

Laser Welding:
While less commonly utilized in ERW pipe production due to its higher cost, laser welding is a technique that provides extraordinary precision and control. A high-energy laser beam is concentrated on the edges of the steel strip, melting them and developing a weld joint.

FAQ

 

Q: What is the production process of HFW steel pipe?

A: The production process of HFW steel pipe mainly includes the steps of steel strip preparation, forming, welding, cooling, sizing, cutting and inspection. Among them, welding is the key link. The heat generated by high-frequency current melts the edge of the steel pipe and presses it together to form a weld.

Q: How to ensure the quality of the weld of HFW steel pipe?

A: The quality of the weld of HFW steel pipe is mainly guaranteed by strict process control and quality inspection. During the production process, the welding parameters such as welding current, voltage, frequency, etc. need to be precisely controlled. At the same time, the weld needs to be visually inspected and non-destructively tested to ensure that the weld quality meets the relevant standards.

Q: What issues should be paid attention to during the use of HFW steel pipe?

A: When using HFW steel pipe, it is necessary to pay attention to its installation, maintenance and maintenance. During installation, it is necessary to ensure that the pipeline connection is firm and the sealing is good; during maintenance, it is necessary to regularly check whether the weld, coating, etc. of the pipeline are intact; during maintenance, it is necessary to take appropriate anti-corrosion measures to extend the service life of the pipeline.

Q: Does HFW steel pipe have a seam?

A: An advantage of HFW steel pipe is that no fusion metals are used and the weld seam cannot be seen or felt. That's opposed to double submerged arc welding (DSAW), which leaves behind an obvious weld bead that must then be eliminated depending on the application.

Q: What are the specifications and sizes of HFW steel pipe?

A: HFW steel pipe has a wide variety of specifications and sizes, which can be customized according to customer needs. Generally speaking, its outer diameter ranges from a few millimeters to hundreds of millimeters, and the wall thickness also varies according to application requirements. Common specifications include various sizes under standards such as ASTM A178,

Q: What are the main application areas of HFW steel pipe?

A: HFW steel pipe is widely used in many fields, including oil and gas storage and transportation, building structures, automobile manufacturing, machinery manufacturing, etc. Especially in oil and gas pipeline construction, HFW steel pipe is favored for its superior performance and lower cost.
