Evidently, rapid advancements in materials and welding techniques have resulted in flawless improvements in the dependability of piping systems adopted throughout industries.
However, as previously stated, there are still piping systems in operation that are prone to corrosion and seam-related issues. As a result, these flaws are found using integrity assessments, and we take rapid action to correct them.
As a result, ERW Piping solutions are currently submitted to non-destructive tests such as ultrasonic testing and pressure testing. Resistance Welding Fundamentals
As a result, the principle involved in resistance welding is that when an electric current is carried through the junction, the resistance of the metal to the passage of the current produces a high temperature. Furthermore, because the contact surfaces are not perfectly in contact and give the most resistance, they are heated first.
As a result, we assess the pressure potential of each individual segment of the piping system during the actual building process, leaving no stone left in our quest for efficiency.
ERP piping systems have been used for a variety of engineering uses, including fencing, scaffolding, and line pipes.
Now, we recommend the ERW pipeline system because of the obvious benefits. Another significant advantage is that these plumbing solutions are cost-effective and operate well in low-pressure applications.
In another timeline, in context to attributes, Electric Resistance Welded steel pipes, ERW steel pipes or high frequency welded pipe for short, it has a number of advantages:
- Provides great production efficiency at a cheap cost, and the pricing for UOE steel pipes is relatively low.
- Physical characteristics include astuteness in size and high precision, better than roundness, spiral welded pipe, which can save a lot of man-hours on-site counterparts.
- Has a smooth surface, a lovely appearance, and is preferred in exterior coating applicators.
Apart from that, ERP piping solutions finds immense importance as
- Water lines It has the potential to be utilised for agricultural and irrigation purposes.
- Pipelines for natural gas (for natural gas)
- Steel tubes are used.
To create a continuous longitudinal weld on our tubing, PNEUMSYS ADVANCE ENERGY SOLUTIONS (PAES) use the electric resistance welding (ERW) technology. To achieve a complete weld, this process is dependent on a number of critical elements.
The most important of these factors are:
- Breadth of the strip
- Preparation of the strip by mill forming and fin pass stands
- Current induction in the strip, current concentration, and subsequent heating of the steel along the strip edges
- Strip edge presentation at the tube mill weld stand
- The ensuing molten metal is squeezed out.
Breadth of the strip Each size of tube produced has a distinct strip width. The strip width is estimated using several characteristics, including the finished tube size, tube wall thickness, desired radius of corners (for square and rectangular tubing), and theoretical molten metal squeeze-out at the weld head.
PAES buys steel coils from primary mills and slits the coils to width on its own slitters. The strip width is limited to 0.020 inches.
Preparation of the Strip An important aspect of getting a good weld is making sure the strip edges are correctly prepped before welding. This is performed by flying over the strip in a sequence of rolls known as fin passes.
As a result, the fin passes are intended to polish the strip edges in preparation for welding and to ensure that the edges are beveled to the right angle to allow the strip edges to join together evenly.
As a result, the strip edges must meet so that there is no gap at the top (outside of the tube) or bottom (inside of the tube).
Furthermore, this assures a uniform amount of extrusion, or squeeze-out, at the weld head (also known as weld pressure rolls). When the two edges meet, a mismatch arises when one strip is higher or lower than the other.
Welding In electric resistance welding, the strip edge can be heated in two ways. One way is to use contact shoes to induce current into the tube. The contact shoes are copper-based contacts that allow current to flow into the to-be-welded base metal. The contact shoes are placed towards the strip edges, just in front of the weld pressure rolls. A high-frequency induction coil is used in the second method.
Our crew is highly qualified and skilled in servicing and manufacturing ERW piping solutions and steel supplies.
As a result, whether you have a huge construction project or want parts for industrial machines, our team of piping solution consultants will ensure that your project has the parts it requires when it needs them.
This way of generating current into the strip is non-contact. This is likewise located front of the weld pressure rolls.
