This product used in coal mining, and falls into coal-mine used water pipes,air supply pipes, guniting and gas drainage pipes,etc. The quality conforms to standard CJ/T189-2007 & MT181.
Quality Assurance: It is the first to get the certificate of 3.5Mpa Coal Mining Safty Mark of China. Its service life can reach over 50 years.
Property Characteristics:
1>Light weight, long service life and easy installation. Its weight is lighter,while its service life is 8-10 times more than steel pipe.
2>Good anti-corrosion property, high pressure resistance, superior mechanical property, which is better than that of plastice pipe. It is widely used in piping project under different conditions.
3>Low noise in media transportation
4>Good sealing property. No leakage afer pressure testing.
5>Easy installation. The patented pipe fittings are developed ourselves. They are convenient to install and need no anti-corrosion treatment or welding work,which can reduce installation difficulty and save lots of working expenses under complex or special environment.
6>Flam-resisting and antistatic performance. Both of them meet the national standard. It can be used in flammable and explosive dangerous place.

Features
Most commonly used , low alloy heat resistant with strong characteristic. Commonly used as heating surface pipes in fire/nuclear /petrochemicals industryGood performance in antioxidant, inoxidability, structure stability as well as perfect processing propertyIts Chrome Content is increased and with better performance in antioxidant, inoxidability than T5, but with weaker heat resistance and welding performance, high anti Coxidantant and anti high temperature corrosion. Stable Toughness / durable plastic / thermal force; T 610,its admissable stress is higher than the austenitic steel, T í¦ 550. Recommended allowable stress of steel is twice as high as that of T9 twice.
In addition to high anti-oxidation, good corrosion resistance, high impact toughness and stable / durable plastic / heat intensity, smelting deformation of micro-alloying to obtain high-density dislocation / highly refined grains, welding performance improved.
Significantly.The increase of W element is significantly improved resistance to high temperature oxidation and to hot corrosion compared with T91. Mo's appropriate decrease improve the stability and availability of welded steel / welded joint. B is the strong element temperature which highly improve the resistance to elevated temperature creep. Its resistance to lasting / creep / corrosion resistance is better than T91.
