Small Diameter Anti-corrosion Spiral Steel Pipe Is Durable

Characteristics of small-diameter anti-corrosion spiral steel spiral tube: Straight seam welded pipe has simple production technology, high production efficiency, low cost, and rapid development. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe. A narrower blank can be used to produce a larger diameter pipe, and a blank having a different diameter can be produced from a blank of the same width.

However, compared with the seamless steel pipe of the same length, the length of the weld seam increases by 30 to 100%, and the production speed is low. Therefore, the smaller diameter welded pipe mostly adopts straight seam welding, while the large diameter welded pipe adopts mostly spiral welding.

Spiral pipe and its standard classification: ssaw steel pipe for pressure fluid transport (SY5036-83) is mainly used for pipelines for oil and natural gas transmission; Spiral seam high-frequency welded steel pipe for pressure fluid transportation (SY5038-83), Spiral seam high-frequency welded steel pipe welded by high-frequency lap welding method for pressurized fluid transport. The steel pipe has strong pressure bearing capacity, good plasticity, easy for welding and processing and molding; general low pressure fluid conveying spiral submerged arc welded steel pipe (SY5037-83) is made of double-sided automatic submerged arc welding or single surface welding method for water, General low-pressure fluids such as gas, air and steam

The factory for the water supply pipeline wall anti-corrosion primer coating; anti-corrosion spiral steel pipe topcoat for the water supply pipeline wall anti-corrosion paint. It can be divided into diameter, diameter, nominal diameter. The outer diameter of the pipe with the anticorrosive spiral pipe is denoted by the letter D, followed by the size and wall thickness of the outer diameter. For example, the anticorrosive spiral steel pipe with an outer diameter of 108, the wall thickness is 5mm, and the plastic pipe can also be expressed as the outer diameter..

The manufacturers are mainly used for conveying pipelines, pipe piles and some structural pipes. Spiral steel pipes, also known as spiral welded pipes, are helically distributed pipes with respect to the pipe axis. Mainly used for conveying pipes, pipe piles and some structural pipes. Due to the increasingly higher carrying pressure of spiral welded steel pipe pipelines, the increasingly stringent operating conditions, and the need to extend the service life of the pipeline as much as possible, the main development directions of spiral welded pipe are: production of large-diameter thick-walled pipes to improve pressure resistance; design and production of new structures.

The steel pipe, such as double spiral steel pipe, is welded to a double pipe with a thickness of half the wall of the pipe, which is not only higher in strength than a single pipe of the same thickness, but also does not cause brittle failure; the development of new steel grades and the improvement of smelting Technology level, extensive use of controlled rolling and small diameter anti-corrosion spiral steel tubes.
