Alloy Steel WP 9 Spool is a pipe fitting that is available in various sizes. This steel is an excellent choice for pipe fittings as it has high corrosion resistance and wears. It is also resistant to impact, softening, and pitting. Chromium increases the hardness and prevents oxidation at elevated temperatures. It also improves the tensile, yield, and hardness properties of low alloy pipes.


These spools are available in various sizes and types. They can be used to connect long pipes that are fitted with flanges on the tip. These spools are installed in the concrete walls before they are poured. Hence, they are crucial parts of a pipe system, as they will need to be run at a later time. These pipe spools are manufactured by Real Engineering Steel and Alloy at its state-of-the-art manufacturing plant in India.


Among the benefits of Alloy Steel WP 12 Spool, one of the most notable advantages is that it has a lower tendency to accelerate intermetallic stages. In addition to this, the WP 9 spools are more flexible than the other alloys. It can also be welded by any normal welding procedure. However, oxyacetylene welding or submerged arc segment welding are not recommended for corrosive services. Additionally, they should be protected from excessive heat input.


Prefabricated spools are an ideal solution for the severe shortage of skilled labor. As they do not require the involvement of a large workforce, prefabricated spools are cheaper to manufacture. They also take less assembly time. This reduces time overruns. These spools also save companies from the cost of testing equipment. Third-party inspection agencies can also service them, thus lowering costs.
