Product Description

Our Patent - YAXING Thermal Expansion Pipe Technology：

·The Thermal Expansion Pipe Machine is invented by Mr. Fu Bingzhong who is the chief engineer of YAXING. Since the first set of Thermal Expansion Pipe Machine developed by the YAXING technology team in 1996, YAXING has successfully designed and manufactured all kinds of Thermal Expansion Pipe production lines with various specifications and requirements for hundreds of large well-known steel pipe enterprises. Small investment and large return, the Thermal Expansion Pipe Machine unit has brought huge benefits for the steel pipe manufacturers.

·The Thermal Expansion Pipe Machine as YAXING patent core technology product, it combines the taper mould diameter Thermal Expansion Pipe technology, high power mid-frequency induction Thermal technology, hydraulic control system and smart digital control together, which is used to produce the large diameter Thermal Expansion Pipes and kinds of non-standard steel pipes with different diameters.

·Especially for the production of small-batch steel pipe with various specifications, that well replenished the scares sizes of pipes and large diameter thick wall pipes in the market. With the Thermal Expansion Pipes widely use, it has formed a complete Thermal Expansion Of Pipe Diameter process industry.

The thermal expansion pipe Technology Features:

·The Thermal Expansion Pipe process is used to heat the expansion mandrel to about 750℃ through the medium frequency induction heating coil to expand the pipe diameter to the required size. And the Thermal Expansion Pipes process is simple and easy operation with intelligent control. That can achieve one worker controls several Thermal Expansion Pipe Machine units at the same time.
·The Thermal Expansion Pipe Machine has replaced the traditional steel pipe production process, and manufactured the pipes of scarce size diameter in the market with low cost, especially suitable for the seamless pipes manufacturing with large OD and thick wall. For example 24”, 36”, 40” etc. The MAX finished expansion pipe diameter up to 56” (1420mm), and the Thermal Expansion Pipe wall thickness can be controlled effectively. So that the Thermal Expansion Pipe manufacturers can meet the different customers’ requirements in a wider range. The Thermal Expansion Pipe Machine is featured with Small batch multi-specification production, flexible change pipe diameter within the processing range, high production efficiency and short delivery time. The Thermal Expansion Pipe Machine can meet the customers’ requirements well, even though the customers ask a small quantity of pipes order.

·When the steel tube is heated to the set temperature, the intelligent temperature control system can keep the temperature constant, so that can ensure the thermal expansion pipe quality and prevent the mandrel from being damaged.
·The thermal expansion data can be displayed and saved in real-time with touch control, and the processing data is traceable for each pipe.
·The flexibility of diameter expansion can reduce the inventory, and achieve the waste pipe reuse.
·The Thermal expansion finished pipe quality is exactly the same as the mother pipe and will not be affected at all. So the Thermal Expansion Pipes have been widely used in various fields.

FAQ-(Frequently Asked Questions)

>Q1: What's the Max diameter expanding ratio?
About 1.6
>Q2: Whether the diameter expanding ratio is the same for different steel pipe materials?
The harder the material, the smaller the diameter ratio, so the carbon steel diameter ratio is bigger than alloy steel, and stainless steel is the smallest.
>Q3: what's the wall reduction of expanded pipes?
About 5% to 8%. That meets all standards.
>Q4: what's the wall thickness tolerance of expanded pipes?
There are too many factors affecting the wall thickness in the process of thermal expansion, so there is not a very accurate wall thickness tolerance. Generally, we just tell the wall reduction amount.
>Q5: What's the pipe length after expanding?
Mother pipe length = finished pipe length×diameter expanding ratio
>Q6: What's the efficiency of thermal pipe expanding machine?
Different pipe specifications and materials heating and propulsion speed is different. The larger the diameter, the thicker the wall, the harder the material and the slower the speed. (reference: φ356×10mm, 400mm/min)
>Q7: Is the working forward speed of hydraulic station same as the heating and propulsive speed of pipe expanding machine?
No. Hydraulic station speed is just the maximum forward speed of the machine. The actual operating speed is much slower than this, and hydraulic station speed only indicates a working capability of the equipment.
Q8: How many people are needed to operate the equipment?
Generally need two people .
Our equipment has a high degree of automation and intelligence, and can operate five production lines by two people per shift without any problems. Labor costs are very low.
