The standard for plastic-coated steel pipes used in tap water supply is CJ/T120-2016, "Plastic-Coated Composite Steel Pipes for Water Supply." The hygienic performance requirements for plastic-coated composite steel pipes in this standard include: 1. Scope. This standard applies to plastic-coated steel pipes used for transporting drinking water. Other diameter fluid transport pipes should refer to this standard for compliance. 2. Normative Application Documents.
First, the steel plates are carefully inspected upon arrival at the factory. The corrugated steel plates must comply with national regulations, with the waveform and waveform spacing strictly adhering to the design drawings. The length and width are determined based on dimensions, as well as lifting, transportation, and assembly conditions. The corrugated steel pipes, high-strength bolts, and nuts must undergo galvanized anti-corrosion treatment before leaving the factory. Each batch of goods is inspected and accompanied by product certificates.
Nestable corrugated culvert pipe offers a fast and economical solution to contractors and owners who require a strong casing to place around an already installed utility line. This can be done easily without disrupting the line to be encased. Also can be used in the petroleum, chemical protection shell pipe, and infrastructure construction.
Technical Specifications: Hot-Dip Galvanized Corrugated Steel Pipe for Culvert
Finger expansion joints are a type of bridge expansion joint designed to handle movement from 80 mm to 1,200 mm.
They can be classified in various ways based on different criteria. First, culverts can be categorized according to construction materials and structural forms, among other standards. By construction materials, culverts can be divided into brick culverts, stone culverts, concrete culverts, and reinforced concrete culverts. Second, based on structural forms, culverts can be classified into circular pipe culverts, arch culverts, slab culverts, and box culverts.
Manufacturer might be requested to provide all the required quantity of the materials for a year at once or to perform two deliveries per year; if need be, however, no minimum quantities are guaranteed.
