Manufacturing Process of Threaded Pipe Fittings

Threaded pipe fittings are pipe components equipped with threads. We supply pipelines and pipe fittings wholesale—handling both procurement and distribution of chromatography accessories and consumables, as well as chromatography instruments, all available in bulk for wholesale purchase and supply. These fittings are commonly used in applications such as water-gas piping, small-diameter water pipes, compressed air lines, and low-pressure steam systems, where they connect directly to threaded pipe ends to form a complete pipeline system. To ensure a secure seal, appropriate sealing compounds—such as thick white paint or lead oxide-glycerin adhesive—are often applied to the threads. The manufacturing processes for threaded pipe fittings primarily include hot-rolled straight-seam welding, spiral double-sided submerged arc welding, forging, forging and pressing, medium-frequency push-bending, cold forming, and hot extrusion, with the largest pipe diameter that can be processed reaching up to 2020 millimeters. We also offer pipelines and pipe fittings for wholesale distribution.

Additionally, we offer chromatography instruments wholesale, along with related equipment. These fittings are commonly used in applications such as water-gas piping, small-diameter water pipes, compressed air lines, and low-pressure steam systems. They are connected to threaded pipe ends to form a complete piping system. To ensure a tight seal, an appropriate sealing compound—such as thick white paint or lead oxide-glycerin adhesive—can be applied to the threads.

Our products are widely used in municipal projects, petrochemical industries, the West-to-East Gas Pipeline project, shipbuilding, and nuclear power engineering, with an annual designed processing capacity of 25 million tons. In 2010, industrial enterprises above designated size achieved an added value of 13 billion yuan, representing a year-on-year growth of 31.7%, accounting for 16.1% of the total added value generated by all such enterprises. Currently, Cangzhou's pipeline equipment manufacturing industry is steadily advancing toward its strategic goals of "Three Enhancements" (scaling up, upgrading technology, and improving equipment) and "Three Highs" (high-end products, high-pressure systems, and high value-added offerings), aiming to boost the industry's overall capacity to 30 million tons. As a result, Cangzhou is poised to become a nationally and internationally recognized "Pipeline Equipment Manufacturing and R&D Base" and the "Capital of Pipeline Equipment."
 
The infrastructure investment plan for the "11th Five-Year Plan" is now well into its middle phase. The explosive growth in investments for highways, railways, and other essential infrastructure, coupled with the steady rise in investments for ordinary residential buildings, has positioned the construction industry firmly in an upward-trending cycle. Meanwhile, amid efforts to build an energy-efficient society and as the nation strengthens its focus on independent innovation capabilities, themes centered around energy conservation and technological innovation are set to become the key drivers of industry development.
