In recent years, SNY Valve actively develop both domestic and foreign markets, SNY branded products are sold at home and abroad. The first half of this year came good news again, the company won the bid for a natural gas pipeline project in Southeast Asia.
The natural gas company holds local licenses to lay, build and operate the city's gas transmission network to supply piped natural gas to local domestic, commercial and industrial users and compressed natural gas to vehicles. The pipeline is about 1,000 kilometers long and will cover more than 24,000 households when completed.
Urban natural gas system is the lifeline of modern city and the important infrastructure of urban construction. And the natural gas supply pipeline is one of the main symbols of urban modernization. Natural gas is a non-toxic, colorless and odorless gas, its main component is methane (about 95% above), and contains a small amount of ethane, propane, butane and other alkanes. The explosion threshold of natural gas is very low, only 5%~15%. It belongs to Class A chemical dangerous goods. Even it is slightly leaked, it is easy to mix with air to form explosive mixed gas, which may cause fire and explosion accidents and even cause heavy casualties. Therefore, this batch of valves are all three-stage full-welded design, and non-destructive testing carried to ensure that there will be no external leakage, ensuring the safety of the whole pipeline.
SNY won the bidding for 16 full welded fixed ball valves with API 5L welded sleeves, maximum nominal diameter of 12 inches (DN300), maximum design pressure of 10Mpa (Class 600), full bore design in accordance with API 6D, fire safe design in accordance with API 6FA, and upstream and downstream single piston seat (DBB), double sealing design (PMSS), anti-static and with locking device and other functions. All products are carried out in strict accordance with the order requirements and standards. The test duration is over one time more than the time specified in API 6D standard. After the test witnessed by the authorized third-party testing institution, with all the properties meeting the relevant regulations, all valves are test passed in one attempt and delivered in recent days.
SNY full-welded ball valve can be widely used in urban gas pipelines, heating pipelines, long distance oil and gas pipelines, as well as steel, chemical, metallurgy, power stations, urban water supply and other fields. In addition to the conventional fixed ball valve function, it also has the following main technical characteristics:
High quality forgings body with advanced welding technology, to achieve a unique anti-deformation design
Simulate analysis of the internal/external force and safety assessment of pipeline force borne by the valve body structure strength
Weld area with non - destructive testing to ensure product safety and reliability
Safety evaluation of welding and CTOD post heat treatment
Weld joints is corrosion tested (HIC/SCC)
The welding process is performed by an IIW certified welding engineer
Optional extended bonnet, suitable for under ground and other conditions
SNY Valve always adopts the diversified international management concept to lead the product design and manufacturing. On the basis of conventional products, we actively develop high temperature, high pressure, ultra-low temperature, high acid resistance, corrosion resistance, wear resistance and other new valve products. The acceptance of these full-welded ball valve once again proved the strong R & D manufacturing capability of SNY, the company will continue to apply new technology, new process, new materials, reduce costs, improve quality, and continue to meet users' requirements and expectations for high-end products.
