FAQ

We respond immediately around the clock to resolve customer issues, providing attentive and worry-free service.

Q: What should I do if a size mismatch occurs during installation?

A:

Download a 3D installation model from official channels to verify dimensions, or contact the sales team for a customized installation instruction video. In an emergency, the technical support team can provide remote video guidance on adjusting installation parameters to ensure a perfect fit.
Q: What should I do if the product's wear resistance decreases during use?

A:

We recommend performing a surface wear inspection after every 500 hours of operation and regular maintenance with a dedicated lubricant. If wear resistance decreases prematurely, provide the operating logs and request a free replacement for an upgraded, wear-resistant connector to extend the life of the equipment.
Q: What is the regular maintenance interval?

A:

We develop differentiated maintenance plans based on industry characteristics. For mining applications, we recommend a leak test every three months. For food processing, monthly CIP/SIP cleaning verification is required. For construction, pressure testing is performed quarterly before construction to ensure equipment is always in optimal condition.
Q: What are the requirements for returns and exchanges?

A:

A full refund is available within 7 days if there is no damage. A free replacement is available within 15 days if confirmed to have a quality issue. Paid repair service is available after 30 days. The original packaging and receipt of purchase must be retained. After submitting an application through the online system, the application will be reviewed and picked up within 24 hours to ensure an efficient and transparent process.
