Design Features of full welded forged steel ball valve
The body of ball valve is full welded,selects high quality forged material,and adopts the advanced forged forming technology to form two semi-spheres which are welded into a whole in the middle of the body.This welding technology differentiates the ball valve form others,and makes the valve more spherically,so the valve structure is more compacter,lighter and stronger.Besides,the middle direct welding realize highly accurate valve body manufacturing,makes fully and completely sealing between the seat and ball.The full welding instead of bolts completely avoids the outside leakage,so ball valve is the ideal product for under-ground,offshore working platform and under-sea equipments.
Adopting fixed plates or trunnion to support the ball
The top and bottom of the ball is supported by upper and lower fixed plates or stem and trunnion,and the ball is accurately placed in the center of the ball valve to achieve complete seals and precise movements.When plate adopted,the force exerted by the medium to the ball is distributed via the plate to the left and right bodies,so that the stem does not bear the blending moment from the medium,but only the torque from the ball rotation during the opening/closing of the valve.The low-friction PTFE Teflon composite bearings installed between the ball axis and fixed plate and between the stem and the trunnion can absorb ball moving action caused by the pressure of the medium.This structure brings stable actions and easy operations for the ball valves,and the required operation torque can be reduced,so smaller actuators can be used,and the cost is cut down.
ball valve seat is floating structure,means the seat can move along the medium direction,so that the seat can fit against the ball all the time.
（Ⅰ）Double piston effect structure seat of full welded forged steel ball valve
Seat design is special double pistons effect structure,it can ensure the seal wherever the medium flows into the ball valve.
（Ⅱ）Seat multistage seal strucute of full welded forged steel ball valve
As following graphic instruction,on seat bearing ring,set two soft sealing rings(A and B)and metal sealing spherical surface which can seal with the ball.Seat ring A is spring loaded,which seals the surface with the ball tightly to the surface to form an initial seat;When there is pressure generated from medium,the piston force is generated to make seal ring A elastically deformed and seal ring B fit the surface of the ball surface due to the piston effect caused by area difference,thus the second seal forms.When the medium pressure is rising.It will generate huge pressure to seal ring A and seal ring B,so the two seals have a greater elastic deformation,then metal seal ball surface compact with ball surface to form the third level of metal to metal seal.
（Ⅲ）Secondary seat seal device of full welded forged steel ball valve
As the above graphic instruction,the secondary seal device(seat grease injection valve)can be chosen according to the actual working condition,medium requirement,seal requirement,etc.Seat ring grease injection valve is a one-way valve,installed on the body,which can prevent the leakage and inject grease under the outside force.When secondary seal is required,there is a grease injecting channel and hole on the seat ring.The grease can form a seal between the seat and the ball,and then stop the leakage.

- Q: How does ductile iron pipe perform in high-temperature environments?
- Due to its unique properties and characteristics, ductile iron pipe performs exceptionally well in high-temperature environments. It is known for its high strength, toughness, and durability, making it suitable for various applications that involve elevated temperatures. One of the main advantages of ductile iron pipe in high-temperature environments is its ability to withstand thermal expansion and contraction. With a low coefficient of thermal expansion, the material can handle significant temperature fluctuations without suffering detrimental effects. This ensures that the pipe remains structurally stable, avoiding deformation or cracking when exposed to high temperatures. Moreover, ductile iron pipe exhibits excellent thermal conductivity, allowing it to efficiently transfer heat. This prevents the accumulation of excessive heat and reduces the risk of thermal stress. Additionally, its high thermal conductivity enables it to dissipate heat quickly, ensuring that the pipe remains within safe operating temperatures. Furthermore, ductile iron pipe has a high melting point of approximately 2200°F (1200°C). This characteristic guarantees that the pipe maintains its structural integrity even in extremely high-temperature environments, making it capable of effectively handling hot fluids, steam, and other substances at elevated temperatures without compromising performance. Another crucial aspect is the corrosion resistance of ductile iron pipe. It is commonly coated with protective linings, such as cement mortar or epoxy, which act as a barrier against corrosion caused by high temperatures. These linings prevent direct contact between the pipe and corrosive substances, thereby ensuring the pipe's longevity in high-temperature environments. In conclusion, ductile iron pipe is an excellent choice for high-temperature environments due to its exceptional strength, thermal stability, thermal conductivity, and corrosion resistance. Its ability to withstand thermal expansion, high melting point, and efficient heat transfer properties make it a reliable and durable option for various applications in such conditions.

Hardness Testing: This method measures the hardness of the ductile iron pipe using various techniques such as Brinell, Rockwell, or Vickers hardness tests. Hardness testing provides information about the material's resistance to deformation, wear, and fatigue. It helps assess the pipe's durability and resistance to external forces. 4. Impact Testing: This method involves striking a notched sample of the ductile iron pipe with a pendulum or falling weight to measure its impact resistance. The test determines the material's ability to absorb energy during sudden loading or impact. Impact testing helps evaluate the pipe's ability to withstand accidental impacts or dynamic loads. 5. Ultrasonic Testing: This non-destructive testing method uses high-frequency sound waves to detect internal defects or discontinuities in the ductile iron pipe. Ultrasonic testing can identify voids, cracks, or inclusions that may affect the pipe's structural integrity. It helps ensure the pipe's soundness and reliability. 6. Magnetic Particle Testing: This method is primarily used for detecting surface or near-surface defects in the ductile iron pipe. It involves applying a magnetic field to the pipe and then applying magnetic particles to the surface. Any defects present will cause the magnetic particles to gather and form visible indications. Magnetic particle testing helps identify surface cracks, laps, or other defects that may affect the pipe's performance. These different testing methods help ensure that ductile iron pipe meets industry standards and specifications, ensuring its quality and reliability in various applications.
