Hebei Huayang Steel Pipe Co., Ltd is one of the leading manufacturers and suppliers of carbon steel slip on flange in China. Please feel free to buy cheap carbon steel slip on flange from our factory. All customized products are with high quality and low price.
Strict selection of raw materials to build a solid quality foundation
Carbon steel flat welding flanges are carefully selected from high-quality carbon steel, and the carbon content is strictly controlled to ensure a good balance between its strength and toughness. Each batch of steel is tested for mechanical properties such as tensile and impact, as well as spectroscopic analysis of chemical composition, and unqualified materials are resolutely eliminated from production. When smelting, advanced extra-furnace refining technology is used to remove phosphorus and sulfur impurities in depth, and titanium, niobium and other trace alloying elements are added to refine the grain, enhance the strength, toughness and corrosion resistance of steel, so as to build a firm foundation for product quality.
Fusion of technology to create excellent quality
The manufacturing adopts hot die forging and precision machining process. When hot die forging, the heated billet is put into a high-precision mould, and the parameters are regulated through the digital system, so that the metal organization is uniform, the grain is refined, and the mechanical properties are improved. After that, it is finely processed with CNC lathe, milling machine and other equipments according to the drawings, strictly controlling the dimensional tolerance of outer diameter, inner diameter, sealing surface, bolt holes, etc., and the sealing surface is polished by special grinding, which guarantees the sealing performance.
Excellent performance to meet various needs
This flange is easy to connect, flat welding structure can be welded on the end of the pipe, which can shorten the construction period. After tempering heat treatment, it has strong pressure-bearing capacity and can withstand high internal pressure, anti-deformation and anti-leakage. Alloying elements and anti-rust treatment allows good corrosion resistance, can work stably in a humid, slightly corrosive environment, widely used in construction water supply and drainage, HVAC, fire fighting and general industrial pipelines and other fields.
Full service to relieve customers' concerns
Pre-sale, the technical team communicate with customers, according to the project requirements and working conditions to provide selection advice and technical advice. In the sale, efficient production and selection of appropriate logistics and distribution, timely feedback on the progress of the order. After-sales service, customer service 24-hour response, provide technical support, free replacement or maintenance of quality problems, but also regular visits to collect views, optimise products and services.
