Hot dip Galvanized Seamless Steel Pipe is a metal pipe produced by Shixinda factory. It uses seamless steel pipes as the base material and applies processes such as hot-dip galvanizing and electro-galvanizing to form a uniform zinc protective layer on the inner and outer walls of the pipe. The base material is made by piercing and hot-rolling / cold-drawing of solid steel billets, without welding seams, which is different from galvanized welded pipes. The galvanized layer isolates air, water vapor, and acidic and alkaline media, achieving long-term corrosion prevention for the pipe, and combining the high strength of seamless pipes with the rust prevention of galvanizing. The mainstream industrial materials are mainly hot-dip galvanized seamless pipes, and electro-galvanizing is only used for mild indoor conditions.

Shixinda is a professional manufacturer and supplier of China Seamless Steel Pipes. This product is made by punching through a whole round steel bar, and it is a steel pipe without welds on its surface, which is called a seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe-in-pipe. According to the cross-sectional shape, seamless steel pipes are divided into circular and special-shaped types. Special-shaped pipes have various complex shapes such as square, oval, triangular, hexagonal, melon-shaped, star-shaped, and winged pipes.

Shixinda Factory Direct Sales Straight Seam Welded Steel Pipe. This product has extremely strong adaptability and flexibility in various scenarios. It can undergo differentiated surface treatments according to different usage environments. The bare pipe is suitable for indoor dry structural materials and does not require complex anti-corrosion treatment, with outstanding cost-effectiveness. After metal coating modification, the pipe can adapt to outdoor open-air, humid and ventilated, and mild corrosion conditions, and can effectively resist oxidation and rusting for a long time. At the same time, the pipe has excellent plasticity and supports processes such as threading, coupling, bending, hole drilling, and precise processing of bevels. It is suitable for various non-standard equipment brackets, customized steel structures, and processing requirements for pipe fittings.

Shixinda Factory has been deeply engaged in the Pre galvanized Round Steel Pipe industry. The quality standards of their products are strictly controlled from the raw material source. Different from post-galvanizing processed pipes, we use high-quality hot-dip galvanized steel strips as raw materials. The steel strips are fully galvanized first, and then welded into pipes through high-frequency rolling. Before the pipe is formed, the steel strips have already formed a uniform and complete zinc coating. Through precise diameter setting and straightening processes, the outer diameter and wall thickness of the pipes are precisely and uniformly consistent. The steel strip and the zinc layer are pre-melted and integrated. The surface coating of the finished pipes is smooth and fine, and it is not prone to zinc peeling or rusting during processing, folding, punching, cutting, etc. The zinc coating on the weld surface is complete and smooth, avoiding the problem of large-scale rusting after processing of ordinary pipes.

The Welded Steel Pipe produced by Xinlida Factory is the most widely used economical steel pipe material in the fields of civil engineering, light industry support, and general steel structure. It is manufactured based on the standardized continuous forming process of steel strips, different from the extrusion and piercing process of seamless pipes. The welded pipe has the core advantages of precise dimensions, uniform wall thickness, high cost performance, and fast delivery speed. It is the main type of pipe material for various conventional fluid transportation, structural support, and framework construction projects.

The Galvanized Steel Pipe produced by Shixinda suppliers is formed by high-precision steel strips through high-frequency longitudinal welding. The seamless galvanized round pipes use national standard 20# seamless base materials for further processing. All formed pipe materials undergo dual factory inspections including eddy current testing and water pressure resistance testing, effectively avoiding common quality issues such as weld cracks, uneven pipe wall thickness, and pressure leakage.
