Pipeline and valve castings are core components of fluid control systems. They provide sealing, pressure-bearing, and flow regulation. As a leading manufacturer and exporter of pipeline and valve castings, QD provides reliable pipeline and valve casting solutions to customers across various industries.
The quality core of pipeline valves
The three most important quality evaluation criteria for customers are:
Material purity—determines core properties of castings, such as corrosion resistance and wear resistance.
Structural integrity—must be free of defects such as cracks and bubbles to ensure safe pressure bearing.
Surface smoothness—affects sealing effectiveness and fluid resistance, minimizing operational losses.
QD implements quality control throughout the entire process:
- Source: Carefully select raw materials. Match materials based on fluid characteristics. Resolutely reject inferior recycled materials.
- Production: Strict control throughout the entire process – stable process parameters, precise temperature and time control. Minimize common defects such as bubbles and shrinkage.
- Factory: Multiple inspections are conducted – for surface smoothness, structural dimensional accuracy, and basic pressure-bearing performance – to ensure that every pipe and valve casting meets standards.
Working condition adaptation: Choose the right pipeline valve castings
Typical working conditions and adaptation solutions
| Working Condition Type | Core Requirement | QD Pipeline Valve Casting Adaptation Ideas |
| Chemical Pipeline | Resistance to acid – alkali corrosion and medium erosion | Select corrosion – resistant alloy materials. Optimize the surface treatment process to enhance chemical resistance |
| Municipal Water Supply | Resistance to rust and guarantee of water quality safety | Adopt food – grade materials. Improve the surface finish to reduce impurity accumulation |
| High – temperature Pipeline | Resistance to temperature difference change and thermal fatigue | Select high – temperature alloy materials. Match the thermal expansion coefficient during design |
| High – pressure Pipeline | High strength and resistance to explosion | Thicken the key pressure – bearing parts. Optimize the structural stress distribution |
Common Pipe and Valve Casting Materials
The performance differences between different materials directly impact their application scenarios:
- Gray cast iron: Offers excellent casting properties and low cost. Suitable for low-pressure, room-temperature water, air, and other media pipelines, such as common municipal drainage systems.
- Ductile iron: Superior strength and toughness to gray cast iron. High impact resistance. Suitable for medium- and low-pressure pipelines, such as municipal water supply and gas transmission.
- Stainless steel: Contains alloying elements such as chromium and nickel. Excellent corrosion resistance. Suitable for pipelines handling corrosive media or clean fluids in industries such as the chemical and food industries.
- Copper alloy: Excellent thermal conductivity and sealing properties. Commonly used in low-pressure applications with stringent sealing requirements, such as plumbing pipes and air conditioning systems.
QD matches customers with precise pipeline and valve casting solutions:
- We clearly define key parameters such as media type, pressure level, and temperature range. We thoroughly understand the operating conditions, including hidden requirements such as frequent starts and stops and the amount of impurities in the media.
- We optimize structural design based on demand—for example, thickening key valve body areas for high-pressure applications. We optimize internal flow lines to reduce resistance for high-flow applications. This ensures that pipeline and valve castings are perfectly matched to the operating conditions.
