Grooved Couplings
HQ Pipeline Co., Ltd. supplies grooved couplings manufactured in China for a variety of pipeline applications. The couplings are cast from ductile iron and carry FM and UL approvals, indicating compliance with stringent safety standards. They feature a grooved connection that simplifies installation and provides a secure, leak‑free joint. The supplier mentions flexible minimum order quantities and offers FOB or CIF shipping terms.
Standard industry practice for grooved couplings includes pressure ratings up to PN16 and adherence to ISO 1610 groove dimensions, which these products typically meet. Typical size offerings span DN15 to DN300, covering most municipal and industrial pipe sizes. A typical tensile strength for ductile iron of this class is around 250 MPa, delivering sufficient load capacity. Corrosion protection is usually provided by a zinc‑rich coating that conforms to standard protective requirements.
These couplings are frequently selected by water utility engineers, fire‑protection system designers and industrial plant managers for reliable fluid transport. Buyers should confirm the exact lead time, payment conditions and any required certifications beyond FM and UL directly with the supplier. Requesting a sample or test data sheet before committing to volume orders helps validate performance for critical infrastructure projects. Since the listing does not disclose specific MOQ or pricing, those details must be negotiated with HQ Pipeline Co., Ltd.
