The introduction of spiral welded pipe/straight seam submerged arcwelded pipe hydrotester

Spiral welded pipe/straightseam submerged arc welded pipe hydrotester mainly is used to have the pressuretesting to spiral welded pipe or straight seam submerged-arc welded pipe. Ituses polyamine to have the end sealing and inner supporting large gas sealingmethods. It is assisted by oil water balance system. Besides, the computer canrecord, store, print and testing the results. Its advantages include pressuremaintaining stability, high safety and so on

The machine adopts the structure of the symmetrical plate tension rod, the center of force is in the symmetry center of the pull rod when testing pressure; the pull beam width on both sides is greater than the maximum diameter of the pressuretesting steel pipe, to ensure both sides security of the hydraulic press when testing pressure, the structuredesign is simple, the strength and stiffness superior, performance stable, easy to maintain and use;

Advantages

1 Pressurizing ways use high pressure intensifier.

2 The control system uses the system of “industrial computer (touch screen) +PLC", has automatic / manual / maintenance three work ways.

3. PLC selects Siemens S7-300/400 series, operation stable; control simple and flexible, has good scalability

4 The high-pressure water pump adopts frequency conversion control, boost rapid and stable, holding pressure fluctuation is small.

5 The host PC (touch screen) software real-time displays by pictures, curves, texts, and data, simple and intuitive.

6 Pressure-testing parameter setting is convenient and flexible and has storage, later called directly.

7 Has a perfect diagnostic function, the computer will provide real-time fault information, easy to maintain.

Q:What kind of material and what heat treatment are used for pressing roller (molding, feeding, cutting force, heavy load, heavy load) of sheet steel rolling machine?: Generally speaking, to consider the use of rollers in the requirements, including: 1., good wear resistance, 2. toughness, 3., high hardness, 4. hardened layer (easy to wear after repeated repair)

Q:Improvement in rolling forming process: The utility model has the advantages of short service life, easy damage and high comprehensive use cost.

Q:What is the surface rolling forming machine process?: Due to the rolling surface of metal plastic deformation, so that the surface microstructure of cold hardening and grain refinement, forming a dense fibrous, and the formation of residual stress, hardness and strength, so as to improve the surface wear resistance, corrosion resistance and compliance.

Q:Introduction of roll forming process: With the progress of technology and the development of production, more and more attention has been paid to the roll forming process.

Q:A roll forming machine, rolling out of the length is always not up to a fixed size, not too small, that is, more than that, what is the cause?: Yes, the width of the bearing plate can be a deviation from the length.

Q:Process mould for rolling forming process: Press forming is an advanced processing technology, and its remarkable characteristics have been paid attention to by the automobile industry at home and abroad.

Q:Material and equipment for roll forming process: The most common type of roll forming is reciprocating flat wire twisting machine. Therefore, for the manufacturers of cold heading machines and screw rolling mills, the design of rolling dies is only a matter of design.

Q:What is rolling forming processing?: Rolling process is a kind of pressure finishing, which is a kind of cold plastic characteristic of metal under normal condition.
