Qingdao Compass Hardware Co., Ltd. is a leading precision investment casting foundry specializing in the advanced Silica Sol Process. We are experts in manufacturing high-integrity, complex pipe fittings and fluid handling components for critical applications across various industries. Our mission is to deliver superior-quality castings that ensure reliability, durability, and performance in the most demanding environments.
We cast pipe fittings from a wide range of corrosion-resistant and high-performance alloys:
Stainless Steel
Duplex & Super Duplex Stainless Steel
Carbon Steel
Nickel-Based Alloys
Surface Finishes
We offer various surface treatments to meet functional, aesthetic, and application-specific requirements:
As-Cast/Shot Blasted: The standard finish, cleaned of residual shell material.
Grinding & Polishing: For a smooth surface finish (e.g., Ra 0.8μm) to reduce friction, improve cleanability, or for aesthetic purposes.
Pickling & Passivation: (For Stainless Steels) A chemical process that removes free iron and forms a protective oxide layer to maximize the natural corrosion resistance of stainless steel.
Electropolishing: A electrochemical process that provides a superior, micro-smooth surface with enhanced corrosion resistance and decontamination properties.
Sand Blasting: Creates a uniform matte or textured surface.
Heat Treatment: Annealing, Normalizing, Quenching & Tempering performed as required by material specifications and to relieve casting stresses.
