A First, check if the seals at the pipe connections are aged or improperly installed. We provide free inspection services; if the leakage is due to quality issues with the pipe body itself, we will replace it free of charge according to the warranty terms and cover the installation guidance costs, ensuring a response to customer needs within 48 hours.

A Our products have a chrome plating hardness of over HV850, providing excellent corrosion resistance under normal conditions. If corrosion occurs due to non-human factors (such as extreme acid-base environments or external scratches), you can enjoy an extended warranty period with proof of purchase; for human-induced damage, we can provide repair solutions at cost to protect customer rights.

A Before installation, confirm that the pipe body tolerance meets the equipment requirements (such as ±0.01mm accuracy), and we provide free technical guidance; avoid violent knocking or excessive twisting during installation. Our professional team can provide on-site installation training to ensure maximum product performance.

A We have a 20,000 square foot digital production base and 40 skilled workers, ensuring rapid delivery within 48 hours for regular orders; in case of special circumstances causing delays, we will proactively communicate and provide expedited solutions such as air freight, and compensate for delay losses as stipulated in the contract.

A The piston rod is made of high-strength cold-drawn seamless steel pipe with excellent fatigue resistance. If deformation occurs due to overload use, we will provide free inspection services; free replacement is provided if it meets the warranty conditions, and for cases outside the warranty scope, we can provide cost-effective repair or customized reinforcement solutions to ensure continuous and efficient operation of the equipment.
