        THT-178B Pipe Hydrotester consists of the frame body of the main machine, the sealing head, pipe-inletting and out letting fixture, water-emptying auxiliary device, high pressure water supply system, electric control system, and fitted with personalized control software to suit the needs of production enterprises, can completely meet the different production users to manufacture the oil tube, pipeline pipe, high-pressure boiler tube, etc., and to subject the finished tube to hydrostatic pressure testing by processing enterprises in accordance with the API standard. Meet the needs of excellent customers with the first-class products.

  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 pressure-testing 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 is the surface rolling forming machine process?
Different from cutting, mirror rolling is a kind of plastic processing. Not only is the rolling workpiece surface roughness moment can reach Ry0.1-0.8 m, and the wear resistance of the surface hardening process has been improved at the same time fatigue strength also increased 30% advantages in cutting can not get.
Q:Improvement in rolling forming process
Can not meet the slender rod, thin-walled tubes and other rigid parts of the processing.
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?
According to my experience, there should be a problem with the boot encoder (also known as the digital wheel). Thank you. I hope I can help you.
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?
Use 40Cr or 20Cr, Cr12.Cr12MoV, quenching and tempering treatment, think of hardness, high point, carburizing, nitriding, and consider adding lubrication device to extend its service life
Q:Process mould for rolling forming process
Rolling forming is more complicated and requires higher than rolling thread. The die design is based on the different shapes of the workpiece, the design of the rolling plate into a cross section or a few sections, can use synchronous type; also can use grading type.
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.
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:Introduction of roll forming process
Not only threaded fasteners industry applications, automobiles, bicycles and other industrial sectors also use rolling forming process, processing complex shapes of parts.
