Gongyi City Yu-water equipment, Ltd. is specialized in manufacturing all kinds of waterproof casing manufacturers, I plant heatstroke casing products with strict production license and inspection reports, and through the national ISO9001-2008 quality management system certification, to allow customers to install Use rest assured that I plant products are mainly waterproof casing according to the national 02S404 waterproof casing waterproof casing Atlas Atlas and S312 air defense and special waterproof casing 07FS02 Atlas manufactured in the present building construction projects and large pipeline construction projects as well as air defense projects construction phase embedded in the wall of the pipe designed with good effect, to facilitate construction of the wall without destroying a good foundation to prevent post-compression deformation along the pipeline leaks. Yu-waterproof casing generally flexible waterproof casing, rigid waterproof casing, waterproof wing ring, basement dedicated sealed waterproof casing, waterproof stainless steel casing, lengthened waterproof casing and other products, our factory can manufacture according to customer demand Other specifications waterproof casing products. Yu-flexible waterproof casing is generally used in relatively high demand for water, such as the subway walls, water room and the location of pipelines with a vibration through the wall, and can be a good way to reduce the pipe wall vibration shocks, while protecting the pipeline above other devices. Rigid waterproof casing for use in general through the wall pipe or cable through walls, waterproofing a switch to less demanding water pipes in the ground to prevent the pipe wall loosening. Basement sealed waterproof casing for use in civil air defense projects now can be a good or even prevent various blast explosive shock wave, to ensure safe operation of the air defense aqueduct and ventilation ducts. Stainless steel pipe used in the waterproof casing is generally corrosive, such as chemical sink. Long waterproof casing for general use or for use in cold regions engineering thicker wall. When buying a waterproof casing waterproof casing models to determine a good next step is to determine the future size of the waterproof casing. Under normal circumstances, wear waterproof casing pipe than playing one or two numbers; eg DN100 flexible waterproof casing: DN100 is the nominal diameter of the pipe to the outside diameter is 108mm; waterproof casing and the outer diameter should be 159mm. Under normal circumstances in the procurement waterproof casing is only reported construction through tube diameter (wearing a tube diameter) on it. Yu-can meet a variety of projects with a waterproof casing welcome to order.
