A high-quality vacuum pump is essential for complete A/C system service. The Poly Run vacuum pumps are known for their durability and reliability. They are designed to withstand harsh conditions and provide years of consistent performance. With a wide range of models available, Poly Run ensures that there’s a suitable pump for every application, whether you're working on small systems or large commercial units. The single-stage design of the Poly Run vacuum pump efficiently pulls a vacuum down to 20 Pa, while the advanced two-stage version can achieve an even deeper vacuum of 3 Pa. These pumps are also equipped with dual voltage options, allowing them to operate on either 115VAC or 220VAC at 50Hz or 60Hz, making them versatile for different environments. Whether you're a professional technician or a DIY enthusiast, the Poly Run series offers a reliable solution for all your vacuum pumping needs.| Voltage | 220V/50HZ | 110V/60HZ | ||

It is mainly used as high-precision structural steel pipes for petrochemical industry, boiler pipes, automobiles and aviation.
Seamless tubing can be made from any of several alloys and metals, such as carbon steel, stainless steel, molybdenum, or tungsten. Seamless pipes are used in those industrial applications that require the highest safety requirements. To produce seamless steel pipes, the solid block is pierced with a piercing plug before the pipe is drawn to the desired size.
Some of the differences between seamless and welded pipes are:
Seamless pipes are extruded and drawn from billets, while welded pipes are produced from roll formed and welded strips.
Due to the higher range of security offered by seamless pipe, it is more expensive than welded pipe.
Seamless pipes are available in relatively short lengths, while welded pipes can be manufactured in longer continuous lengths.
Seamless pipe generally does not show any signs of corrosion until and unless it is subjected to a highly corrosive environment, whereas in welded pipe the welded area is more susceptible to corrosion attack.
The welded area is considered to be inhomogeneous, so it exhibits different ductility and lower corrosion resistance, as well as larger dimensional changes. Seamless pipes eliminate any such problems and thus offer high corrosion resistance.
