Cold rolled pipe mill is an equipment used for producing cold rolled pipes, mainly used for processing various specifications and materials of cold rolled pipe products. It usually consists of multiple components, including a feeding system, a curling system, a cold rolling system, a shaping system, and a cutting system.
The working principle of a cold rolling pipe mill is to roll metal strips through multiple rollers to obtain the desired shape and size without heating. This cold working method can improve the strength and hardness of the metal, while avoiding possible deformation and damage during the hot rolling process.
Cold rolled pipe mills are widely used in fields such as construction, machinery, automotive, aerospace, etc. The cold-rolled pipe products produced have the characteristics of smooth surface, precise size, and stable performance. In modern industrial production, cold rolling tube mills have become one of the indispensable and important equipment.

Equipment Introduction

The water pressure testing machine for straight seam welded pipes and seamless steel pipes is mainly used for non-destructive pressure and leakage testing of steel pipes. Water pressure testing is also the most effective and intuitive way to inspect the quality of steel pipes, and the requirements for equipment operators are also very low. Our water pressure testing machine can measure up to 5 steel pipes at the same time, and is equipped with comprehensive safety protection facilities to ensure personnel safety. The equipment is equipped with computer recording, storage, and printing of test results, and can independently monitor the pressure curve of each test product in real time. Currently, the maximum test pressure of our water pressure testing machine can reach 100Mpa.
Fully automatic process flow: Input the length and pressure of the pressure measuring tube - automatic positioning of the equipment - pipe discharge - upper pipe - head - flushing and emptying - sealing and pressurization - pressure holding - pressure relief - drainage - outlet pipe. "
