Seamless steel pipe grouting pipe

Grouting pipe is a pre-buried grouting system, which is widely used in concrete structures to seal construction joints, cold joints, pipe seepage joints, and gaps between ground and walls. Grouting pipe system is particularly suitable for the treatment of new and old concrete joints, and can effectively prevent water penetration. It can not only be used for permanent sealing of concrete structures to ensure the waterproof performance of joints, but also is convenient for construction. It can be cut according to the actual length required, and the construction site is easy to operate without special installation equipment. Grouting time can be flexibly selected according to needs. Grouting can be carried out after the concrete curing is completed, or it can be carried out at any time according to the leakage situation. In addition, grouting pipes can be injected with various types of slurries, such as cement slurry, polymer slurry, polyurethane chemical slurry, etc., to meet different engineering needs. The design and material selection of grouting pipes enable grouting at relatively low pressure to ensure that the slurry can evenly fill the entire pipe.‌ According to different specifications and materials, grouting pipes can be divided into ordinary grouting pipes, grouting steel flower pipes, casing valve pipes, advanced small conduits, disposable plastic grouting pipes, pipe shed pipes and other series. ‌ The general specifications of ordinary grouting pipes are 25mm and 32mm, and the single length is 6m. The material is generally seamless pipes. According to the connection method, they are divided into steel wire and spiral pipes. ‌ Grouting steel flower pipes usually adopt 42mm and 48mm specifications, and use Q235B seamless pipes. The processing methods are generally pointed, punched, and welded barbs. ‌ These different types of grouting pipes are suitable for different engineering needs and scenarios.
