Haihao High Pressure Flange &Pipe Fitting Group Co.,Lid

Haihao High Pressure Flange & Pipe Fitting Group Co., Ltd. has been operating since 1982, giving them decades of experience in high-pressure pipe fittings — a niche requiring precision and reliability. Their product range includes seamless steel pipe, flanges, pipe valves, and butt welders, which are critical in oil, gas, and industrial infrastructure projects. Despite having a long history and clear product specialization, none of their verification details — phone, documents, work email, or account email — are confirmed. This lack of verification raises concerns about legitimacy and responsiveness, especially for buyers needing to validate supplier credentials before placing large or high-risk orders. In international trade, verified contact and documentation are essential for building trust and reducing fraud risk. Buyers should request additional proof or a third-party reference before engaging with this supplier.
