Supply & Demand

A flange is a part that is connected to each other between shafts and is used for the connection between pipe ends. There are also flanges used on the inlet and outlet of the equipment for the connection between two devices, such as reducer flanges. Flange connection or flange joint refers to the detachable connection of flanges, gaskets and bolts connected to each other as a set of combined sealing structures.

Reducer is a kind of pipe fitting (accessory) which is used in process piping to change the pipe size from a big bore to a smaller bore pipe. Mostly reducer use for a change in pipe size to meet flow requirements of the process system or connect to existing small or big piping bores as per requirements. The length dimension of the reducer is almost equal to the average of the big bore and smaller bore pipe diameters. 

Elbow is a pipe fitting that changes the direction of the pipe. According to the Angle, there are 45° and 90°180 "three most commonly used, and other abnormal Angle elbows such as 60 'are also included according to engineering needs. The methods of connecting with the pipe are: direct welding (the most commonly used way) flange connection, hot melt connection, electric melt connection, thread connection and socket connection. The production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow and so on.

Fully Automatic 5G Intelligent Polishing Machine supports one-click startup and automatic intelligent parameter adjustment. Energy-saving and stable in operation, it delivers high-precision, consistent glossy finish with large continuous production capacity. Built with premium core parts, the machine features solid structure, low maintenance cost and less downtime, greatly cutting labor expenses vs traditional equipment.

Fully Automatic Square Tube Polishing Machine is designed for high-efficiency surface polishing of square and rectangular tubes. Equipped with intelligent size adjustment and automatic feeding structure, it realizes full automatic operation without manual intervention. Adopting advanced control system and precise polishing technology, it delivers uniform, high-gloss surface finish with stable processing effect. Featuring high efficiency, reliable performance and easy operation, this machine meets strict high-quality surface requirements for metal tube production.

The three-line cold drawing bench is a specialized piece of equipment for the cold drawing of tubes and bars. It applies high tensile force to pull metal tubes to predetermined specifications, altering their diameter and length to achieve the required dimensional accuracy. Its core features include: the ability to draw 1 to 3 tubes or bars simultaneously, delivering production efficiency several times higher than that of single-line units; the use of small-pitch chains and a double‑chain structure to reduce the polygonal effect and improve bamboo‑like surface defects; fully automatic functions covering feeding, mandrel insertion, drawing, and discharge; a drawing carriage running on high‑precision guide rails, ensuring high dimensional accuracy and excellent surface finish of finished products; and the cold drawing process itself, which refines the grain structure and enhances the strength and hardness of the material.
