Technical Support Case Study



Case 1


Receive the customer’s inquiries and report of failures → analyze the working conditions and failure mode → apply design optimization solutions → confirm the final design solutions → put into production → acceptance and delivery → follow up and validate




The valve is designed for applications at a pressure of 22.45mpa, max temperature of 510℃, a maximum closing pressure difference of 22.45Mpa, an inlet pressure of 20.52Mpa and an outlet pressure of 0.86Mpa in operation, a working temperature of 410, and an average flow rate of 8000kg/h under normal conditions (half switching time, so the flow rate is 16000kg/h on opening).




The medium that flows through the valve is LPH high resolution oil residue, with a density of 1200kg/㎥, a dynamic viscosity of 50mPa·s, a solid content of 53.6%, and a gasification capacity of 1.5% ~ 10%. The valve core is eroded by the fluid medium containing solid particles, which leads to valve failure. According to Preston's grinding empirical formula, the erosion of the valve plug is proportional to the velocity and pressure of the fluid around the plug.







Case 2




Background :

The demand for petroleum is increasing year after year, and the reserves of petroleum exploitation are decreasing year after year. The development of coal-to-oil technology has effectively alleviated this energy problem. However, the harsh environment faced by coal-to-oil makes its requirements for materials and equipment very high. As a key core component of coal-to-oil technology, the demand for one-way valves is growing rapidly, but the R&D and production of one-way valves was monopolized by Germany in the early years, the unit price is very high, and the service life is only 1 to 3 hours, all of these were seriously restricting the development of coal technology.



Solutions :

In order to meet the large demand for one-way valves from customers in the coal-to-oil field, Seed concentrated on researching the production technology of one-way valves and evaluated the independent production of key parts and components of coal-to-oil equipment. The achievement breaks the monopoly of overseas production and our technology made a major contribution.



Achievement:

Autonomous production of one-way valves realizes the reduction of the price to 1/9 of the original, saving costs, and greatly improving the service life. It was reported by CCTV News Network "Ingenuity and innovation, showing a new business card of made in China."






Case 3




Seed has developed 3D printing materials and processes since 2015 and we are the leading pioneer in developing additive manufacturing methods for making downhole drilling tools. Seed has achieved a great industrial breakthrough to print PDC matrix drill bits using tungsten carbide/metal composites manufactured by electron beam melting printing process in a vacuum. This breakthrough has received wide attention and renowned recognition internationally.  The printed bit meets the requirements of drill bit design in terms of accuracy, strength, and surface finish. In addition, the accuracy is even much higher than that manufactured through the traditional molding process. The bit exhibits higher fracture toughness, wear resistance, and erosion resistance compared to the conventional infiltrated PDC matrix bit. This additive manufacture process increases PDC bit design flexibility, capable of producing bits with various features that the conventional infiltration process fails to fulfill.



The 3D printed matrix drill bit not only improves the overall mechanical performance of the drill bit, but saves production costs of the drill bit, and improves the drilling efficiency. This has brought significant economic and social benefits. The company currently designs and 3D prints PDC drill bits, which have been used for drilling bedrock and harsh conditions in domestic oil/gas wells.
