Internal and external corrosion Steel Plant | Ruijie Pipe (certified) | external corrosion steel pipe

Internal and external corrosion Steel Plant | Ruijie Pipe (certified) | external corrosion steel pipe provided by the Tianjin Steel Pipe Co. Ruijie. Ruijie Tianjin Steel Pipe Co. (www.rjggjt.com) is specialized in the "spiral steel pipe, corrosion steel pipe, insulation pipe, welded pipe," the business, the company adhering to the "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: pay by blog. Tianjin Pipe Co., Ltd. Ruijie produced coal tar epoxy structure: coal tar pitch + epoxy resin + filler made of anti-corrosion coating on the steel surface with a glass cloth as the strengthening of internal and external corrosion coating formed by coating steel pipe, commonly used the pipe wall corrosion. Thickness is 0.5 ~ 1.0mm. Coal tar epoxy anti-corrosion steel corrosion using a relatively simple and practical form. His advantage is that lower production costs, applicable to the construction site in Tianjin and external corrosion corrosion steel pipe manufacturers in recent years, the use of coal tar epoxy anti-corrosion steel pipe corrosion practical IPN8710 toxic drinking water pipe band gradually increased. Wall thickness is an important parameter for internal and external corrosion Tianjin Steel Plant, the design equations in the pipeline, "Mechanical Design Handbook" Section 3 gives the wall thickness: S = PD / (2 [δ] ψ) + C where: S: Pipe wall thickness (mm) P: tube medium pressure (MPa); D: tube diameter (mm); [δ]: pipe operating temperature allowable stress (MPa); j: coefficient of longitudinal welds pipe, seamless j = 1; welded steel pipe j = 0.8; C: wall thickness value (mm); including making negative deviation C1; corrosion allowance C2; ??thread depth C3; C = C1 + C2 + C3. Steel reinforcement embedded within the plastic-lined pipe wall thickness is determined by the above theory. Xu piping material stress [δ] generally based on the strength of the material divided by the safety factor corresponding to take the lowest value as the material allowable stress, the stress on the piping material to allow the value. And because the inner ribs embedded lined pipe connection using snap ring buried and external corrosion steel pipe, cold extrusion system slot, without regard to the added value of the wall thickness of C3. Thus, compared with the traditional galvanized steel pipe, wall thickness is more reasonable, there is significant economic potential.
