This pipe induction annealing machine is based on energy-saving bright solution treatment equipment, with improvements in product safety and intelligent control: the heating power supply uses a new DSP+IGBT structure, adopts a DSP fully digital control system, and is equipped with comprehensive self-protection and self-diagnostic functions. The inductor, specially developed for the characteristics of stainless steel, is 15% more energy-efficient than similar products.

The automatic packing machine (standard machine) consists of four main parts: feeding machine, packaging host, strapping machine, and palletizing machine. The packaging equipment is simple to operate, highly efficient, and reduces production costs. The new packaging method completely solves the problems of low efficiency, complex specification conversion, and poor compatibility of pipe specifications in traditional manual (or equipment) bagging and all horizontal packaging.

Hangao's fully automatic bagging machine is a highly integrated industrial automation device capable of autonomously completing the entire packaging process from metering, filling, sealing, coding to finished product output. It is typically driven by an intelligent control system, achieving high-speed, continuous material handling through precise coordination between sensors and robotic arms, and supports customized packaging solutions.

Rolling​‍​‌‍​‍‌​‍​‌‍​‍‌ dies on a welded pipe production line are essentially a well-synchronized mold system. These rolls are not designed primarily for "rolling and compression," but for forming and sizing. The molds for the rolling dies guide the edges of the strip steel by bending the successive stages of deformation, which eventually result in a closed tube. This tube, by welding and subsequent processing, becomes a final product of welded ​‍​‌‍​‍‌​‍​‌‍​‍‌pipe.

Hangao​‍​‌‍​‍‌​‍​‌‍​‍‌ external tube polishing machine is mainly used for metal surface treatment. In addition to that, it can perform various functions such as polishing, cleaning, and deburring. Such work can be done in one go. It eliminates a series of problems of the traditional method of difficult polishing, long time, and large consumption of ​‍​‌‍​‍‌​‍​‌‍​‍‌consumables.

Hangao​‍​‌‍​‍‌​‍​‌‍​‍‌ internal pipe tube polisher sander is designed mainly for internal treatment of metal pipes. Besides that, it can perform multiple functions such as polishing, cleaning, deburring, and other precision grinding work can be completed in one go. It helps to eliminate a series of problem, which includes traditional polishing being difficult, time-consuming, ​‍​‌‍​‍‌​‍​‌‍​‍‌etc.

This​‍​‌‍​‍‌​‍​‌‍​‍‌ system is mainly designed to automatically correct and track stainless steel seam tubes during the TIG welding process, thus eliminating the problem of increased labor costs and poor-quality welding caused by visual fatigue. More specifically, it uses advanced intelligent vision technology combined with optical and electrical technology to achieve this integration. No similar product of this system has been found in the domestic market yet. By capturing the weld bead and dock bar image through the visual acquisition system, the system determines the dock bar offset by the application of vision technology, thus it real-time controls the position of the dock bar by motor device correction,which leads to tracking automatically and realizing unattended high-quality welding requirements ​‍​‌‍​‍‌​‍​‌‍​‍‌finally.

In​‍​‌‍​‍‌​‍​‌‍​‍‌ the industrial welded pipes sector, attaining top-notch welds can be primarily achieved by lowering the welding speed and guaranteeing the welding quality. But to both boost the production line efficiency and get great welding quality, the arc welding stabilizer created by our company is targeting the above problems. At the very center of the arc stabilizer, a longitudinal electromagnetic field with an adjustable size has been added. The arc is either stabilized in the middle or pushed forward by electromagnetic force. Thanks to the electromagnetic stability, the arc cannot be pushed back or to the left by the problems of stagger and "hump" not occurring. So it is a kind of quality assurance that goes hand in hand with production efficiency improvement. The speed has been increased by 20-30% and has been verified in implementation and use. To be able to work with a variety of welding currents and production speeds, regulate the electromagnetic force's strength, and be compatible with different welding currents and ​‍​‌‍​‍‌​‍​‌‍​‍‌speeds.

An​‍​‌‍​‍‌​‍​‌‍​‍‌ air tightness equipment is a precision instrument that can be used to find leaks in products or parts and to measure the leakage rate. Basically, it involves filling or emptying through air the product or device under test, then checking pressure, flow, or gas level changes to decide whether the sealing of the product is good enough. Besides an air-tightness testing device being the cornerstone of a quality control system, it is also a major factor in safety, performance, durability, and environmental regulation compliance of the ​‍​‌‍​‍‌​‍​‌‍​‍‌product.
