Why is the roll molds so important? 

Because in the welding pipe forming stage, the mold is a key factor affecting the molding accuracy. In the sizing stage of the pipe making, the adjustment of the mold and the quality stability affect the quality of the entire pipe and whether it can meet the relevant standards.

What kind of roll mold is considered a high-quality mold?

Hangao's roll molds must be made of Cr12MoV material, which has many advantages, such as high hardenability, hardenability and high wear resistance; Good high temperature oxidation resistance, good rust resistance after quenching and polishing, small heat treatment deformation, etc., especially suitable for making molds with high standards and high requirements, the disadvantage is that the relative price is relatively high.

The processing process is standardized and the details are highly controlled

Every step of Hangao's roll molds production process is strictly in place. In order to control the precision of the roll mold within ±0.02mm, after the heat treatment, the price of the grinder and the processing of wire cutting were increased at any cost, all in order to allow customers to maximize the quality control details and the precision of the welded pipe during the production process.

Good equipment needs excellent technical personnel to control, and good welded pipes need high collaborative work of various equipment and components to produce. Good equipment is the basis for the production of good products, and only high quality and high precision roll molds can play out the characteristics of the equipment.

Every time the finishing tube is rolled, it must go through the process of solution treatment. Ta ensure that the performance of the steel pipe meets the technical requirements. and to provide guarantee for the post-process processing or use. Bright solution treatment process of ultra-long seamless steel pipe has always been a difficulty in the industry.

Traditional electric furnace equipment is large,covers a large area, has high energy consumption and large gas consumption, so it is difficult for realize bright solution process. After years of hard work and innovative development, the use of current advanced induction heating technology and DSP power supply. Precision control of heating temperature to ensure that the temperature is controlled within t2C,to solve the technical problem of inaccurate induction heating temperature control. The heated steel pipe is cooled by "heat conduction"in a special closed cooling tunnel, which greatly reduces the gas consumption and is more environmentally friendly.
