1) Better Price


New machine: The price of new high-frequency pipe welding machines is high.
Second-hand (refurbished / 80% new): The initial investment can help customers save 50% - 70%.
Small and medium-sized factories / new customers: Insufficient budget, difficult to obtain loans, and not wanting to invest heavily in fixed assets. Second-hand Steel Pipe Machine is their best choice.
Export customers (Brazil, Argentina, Southeast Asia): High exchange rate fluctuations, expensive financing, and even less willing to spend a large amount on new machines.


2) Stable pipe production, less downtime, and fewer repairs


Many second-hand pipe manufacturing machines are from domestic first-line brands, with thick materials and solid structures, being more durable than new machines.
After refurbishment, the accuracy can reach 90% - 95%, sufficient for making ordinary carbon steel pipes, galvanized pipes, and stainless steel pipes.


3) Fast production start-up, can be operational within 30 days, while new machines take 3 - 6 months


Second-hand ERW machine: Complete machines ready, complete molds, and intact circuits. Installation and commissioning can be completed within 7 - 15 days and start production immediately.
New ERW machine: Customization, production, delivery, installation, commissioning, and training, generally taking 3 - 6 months.


4) Common parts, low maintenance costs, no worries about repairs


Main models (such as 50/76/89/114 high-frequency welding machines) have a large market share. Rollers, blades, high-frequency heads, and bearings are available everywhere, with transparent prices.
New machine: Specialized parts, monopolized by the original factory, expensive, and slow delivery, and high maintenance costs in the later stage.


5) Market demand: Many small orders, diverse specifications, and second-hand is more flexible


Now in the pipe manufacturing industry: Few large orders, many small orders, frequent specification changes (round pipes, square pipes, rectangular pipes).
Second-hand machinery groups have strong adaptability, quick mold modification, and good flexibility, suitable for multi-variety and small-batch production.
New machines pursue high speed, high output, and a single specification, but are not suitable for the current market.


6) Low risk, easy resale, slow depreciation


Second-hand: Purchased machines have already depreciated by half, and can be sold again in 3 - 5 years, with very little loss, and even retain value.
New machine: The first 3 years have a rapid depreciation rate, and once the market conditions are poor and orders decline, it is difficult to sell.
Overseas customers (especially South America): Unstable policies, large market fluctuations, more inclined towards light assets and low risks.


7) Technology is mature, there is no need to chase new trends


High-frequency pipe welding machine technology has remained basically unchanged for 30 years, with very mature core principles, structures, and processes.
The so-called "upgrade" of new machines is mostly about automation, appearance, and frequency conversion, which have limited improvement for ordinary pipe manufacturing (water, gas, structural pipes), but the price is much higher.

 

Recently due to there are many customers asked our Yashanway to supply some second hands ERW welding machines, so we Yashanway supply below machines for choosing.
