Zhejiang Ruimai Precision Steel Tube Co., Ltd is a high quality (first class in China) manufacture and supplier of seamless stainless steel tubes and pipes, main products including Stainless Steel Hydraulic Tubing, Stainless steel instrument tubing, Stainless steel heat exchanger tubes, high precision Bright annealed seamless tubes, Flowline pipe / line pipe，Duplex steel /super duplex steel seamless tubes, etc. Zhejiang Ruimai precision steel tubes had been specialized in manufacturing and supplying stainless steel seamless tubes since the year 2005. We moved to the new factory in the year 2011. The main technical team & production team were mainly from the biggest and best seamless stainless steel tubes factory in China, they had specialized in this industrial field for more than 20 years.
And since the year 2015, our company invested in a honed tubing and chrome plated bar factory, and we started supply honed tubes and chrome plated bars.
The factory we invested in is one of the professional and the leading chrome plated bar, chrome plated tube and honed tube manufacturer and honed tube suppliers in China. Our factory manufactures honed tube and chrome plated bar, chrome plated tubes for hydraulic cylinder applications for more than 20 years.
Our honed tube factory covers an area of 40,000 square meters and a building area of 30,000 square meters, of which the production plant area is 25,000 square meters. We produces cold drawn seamless tubes, honed tubes / honed steel tubing, hydraulic cylinder tubes of more than 20,000 tons, and we manufacture hydraulic piston rods of 500 thousand meters.
Main Products
Here below are our main product range.
1. Honed tube
Honed tube also is known as honed cylinder tube, it is our most important product line, our factory manufactures honed tube with more than 20 years' experience. Our honed tube is produced from suitable to hone seamless cold drawn tubes. Our factory can manufacture honed tubes in a wide range of carbon steel and stainless steel. The size range covers from ID 32 mm to ID 500 mm.
2. Chrome plated bar
Chrome plated bar is another main product of our factory, this product is known as hydraulic chrome plated rod also, it is mostly used as hydraulic piston rod. Our chrome plated rod is produced from steel round bar by high precision polishing, and with chrome plated surface, the thickness of chrome plated layer is usually min. 20 microns. Our factoy can produce chrome plated bar in carbon steel as CK45, and stainless steels. The size range of our chrome plated bar is from diameter 6 mm to 800 mm.
3. Chrome plated hollow bar
Chrome plated hollow bar is known as Chrome plated tube also, it has the same function with chrome plated bar, but with much lighter unit weight than that. Using chrome plated hollow bar, the hydraulic cylinder weight will be greatly reduced, so the hydraulic cylinder will be more energy efficient. Our chrome plated hollow bar is produced from seamless hollow bar, by polishing the surface and chrome plated it.
4. Cold drawn seamless tubes
Cold drawn seamless tube (CDS tube) is widely used in many industries, such as fulid transportation, machine manufacturing, hydraulic systems and so on. CDS tube is the mother tube of honed pipes.
As the Innovative factory, our product range is keeping growing, customer will be able to get more and more tubes related to steel pipes and tubes in industries.
