J826 Multi-Times Reusable Culvert Rubber Balloon Reduce Construction Material Cost

Our inflatable core molds are mainly made of high - strength rubber (such as natural rubber or synthetic rubber like neoprene) and reinforced fabric (like polyester or nylon cord). The rubber provides excellent elasticity, abrasion resistance, and weather resistance, while the reinforced fabric ensures the product can withstand high internal pressure and external forces during use, greatly extending its service life.

Yes, we can. We understand that different projects have different size needs. Whether it's a non - standard diameter, length, or special shape, our professional design team can work with you to develop a customized solution. Just provide us with your detailed requirements (such as the size of the ship or structure it will be used for, working environment conditions, etc.), and we will produce a product that perfectly fits your needs.

First, check the product for any damage before inflation. Then, connect the air inlet of the inflatable core mold to a suitable air source (such as an air compressor). Inflate it slowly according to the recommended pressure (usually marked on the product or provided in the manual). During use, make sure it is placed in the correct position and avoid contact with sharp objects. After use, deflate it gradually and store it in a dry, cool place away from direct sunlight. We also provide detailed in

Under normal use conditions (correct installation, proper inflation pressure, and avoidance of extreme environments), our inflatable core mold can have a service life of 5 - 10 years. However, factors such as frequency of use, exposure to harsh marine environments (like saltwater corrosion, strong UV radiation), and improper maintenance may affect its lifespan. Regular inspection and maintenance (such as cleaning, checking for air leaks) can help extend its service life.

Yes, we do. We offer a one - year warranty from the date of delivery. During the warranty period, if there are any quality problems (such as air leakage due to manufacturing defects), we will provide free repair or replacement services. After the warranty period, we still provide technical support and repair services at a reasonable cost. Our after - sales team is available 24/7 to answer your questions and solve any problems you encounter.
