Import Grooved Coupling And Fitting — Buy in Bulk from Supplier in China

Weifang Yinuo Casting Co., Ltd. offers a grooved coupling and fitting manufactured in China for industrial piping systems. The product is cast from ASTM A536 Grade 65-45-12 ductile iron, providing a balance of strength and ductility. It complies with ISO and SGS certifications as stated by the supplier. The design incorporates a grooved interface that enables quick assembly and reliable sealing in both heavy-type and general-type applications.

Typical grooved couplings in the market meet pressure classes up to PN16 and adhere to ISO 1610 dimensions, which this item follows as a standard practice. Standard size ranges run from DN15 to DN300, allowing compatibility with a broad spectrum of pipe diameters. A typical tensile strength for Grade 65-45-12 ductile iron is around 250 MPa, delivering robust load-bearing capability. Corrosion resistance is enhanced by a protective coating that meets common industry expectations for water and oil-field environments.

These couplings are commonly specified by construction contractors, plant engineers and plumbing contractors for projects in construction, oil and gas, and manufacturing facilities.
