High Pressure Forged Steel Valve Seat for Oil & Gas Pipeline Mud Pump Valves

Product Description

Exceptional Comprehensive Mechanical Properties
Advantage: 20CrMnTi achieves an excellent balance between strength, toughness, and plasticity.
Detailed Explanation: The chromium (Cr) and manganese (Mn) elements in its chemical composition effectively strengthen the ferrite matrix and refine the grain structure. This grants the valve body high yield strength and tensile strength under high pressure while maintaining good elongation and impact toughness. This means the valve can withstand system pressure shocks, water hammer effects, and unexpected loads, preventing brittle fracture and ensuring structural integrity and a safe service life under complex operating conditions.

Superior Heat Treatment (Carburizing and Quenching) Processability
Advantage: This material is widely recognized as a premium carburizing steel, ideally suited for parts requiring "a hard surface and a tough core."
Detailed Explanation: Valve seats and sealing surfaces require extremely high surface hardness to resist medium erosion, wear, and galling. Through carburizing and quenching, 20CrMnTi can form a high-hardness (HRC 58-62) wear-resistant layer on the surface, while the core retains excellent toughness (HRC 33-45). This "hard outside, tough inside" characteristic perfectly meets the dual requirements of the valve: the sealing surface needs high wear resistance, and the valve body needs to withstand overall stress to prevent cracking.

Valve and seat make up a valve assembly that is the maior component of the fuid end of the mudpump. it is also one of the mostconsumed vulner-able part during driling. Our valve assembly ismade of high-quality forged alloy steel. t has anenhanced strength by aprocess of carbonizaion atthe working surace. Through precise calculationand advanced NC machining, our valve assemblycan realizea favorable match between the valvebody and the seat. Moreover, material is select-able as per different working situations. Thus, the-lifespan of the valve assembly can be prolonged.

Product Description

For valves that open/close frequently or are exposed to high-velocity fluid media, the valve seat sealing face endures cyclic contact stress. The fine martensitic structure and high surface hardness formed in 20CrMnTi after carburizing and quenching significantly delay the initiation and propagation of fatigue cracks and greatly reduce wear caused by particle medium erosion or relative motion of friction pairs. This helps maintain a tight seal over the long term, extends valve service life, and reduces maintenance needs.

Detailed Explanation: Compared to higher-end special alloy steels, 20CrMnTi has mature smelting and rolling technology in China, ensuring stable material supply and relatively controllable procurement costs. Its excellent heat treatment performance means ideal properties can be achieved with standardized processes, reducing process complexity and scrap rates. This allows valve products to guarantee high-end performance while maintaining more competitive manufacturing costs and market pricing.

Detailed Explanation: Manufacturing valve bodies and seats requires extensive machining like turning, milling, and drilling. In its annealed or normalized state, 20CrMnTi has moderate hardness, resulting in low tool wear, good chip-breaking performance, and the ability to achieve high machining accuracy and surface finish. This is beneficial for ensuring smooth flow passages and precise mating of sealing surfaces. Furthermore, this material has a long history of application in global and domestic manufacturing; its machining and heat treatment specifications are very mature and stable, facilitating high-quality, mass production.
