Product Introduce

A hydrostatic pressure testing machine (hereinafter referred to as hydraulic press) is used to test whether the pressure resistance of steel pipe is up to the required level of equipment. By filling the steel tube sealed at both ends with water (or emulsion) and pressurizing it to a certain pressure value, it is observed whether the steel tube can maintain the pressure, so as to determine whether the steel tube reaches the corresponding steel grade.

Main technical parameters of water pressure testing machine:

Implementation standard:

GB/T 6111-2003 Test method for resistance to the internal pressure of thermoplastic tubes for fluid transport

Application scope of hydraulic testing machine:

valves, steel pipes, hose, joints, cast aluminum shell, ball milling cast iron, pressure vessels, gas cylinders, motor shell, pump shell, plastic pipes, water heaters, tanks, pipe fittings, tankers, tanks, and other different products.

A: We do T/T.
Q: What info do you need before giving me the price and proposal?
A: Since we design individual machines based on our customer's requirements, we need your desired products' basic dimensions, including all the pipe diameter(or tube length), thickness range, usage, raw material steel grade, coil weight, and degree of automation.
Q: What should I do if I just start a new business?
A: Contact us immediately, we provide a free consultant for pre-sales service. Also, we can help you solve the raw material (steel coil) purchase, worker training, international market price, and more.
Q: How do you do QA?
A: We have a special team to do strict QA, this is one of our strengths:
(1)Every gearbox will be tested for 8 hours with oil inside to guarantee there is no leak.

(2)Every shaft will be inspected for centering jumpiness.
(3)Every roller will be checked to make sure it's in the range of tolerance critical parts will be inspected for all dimensions.
Q: Why I should choose you? what are the differences between you and other Chinese suppliers?
A: We are concentrating on pipe-making machines for more than 20 years. We have constructed many steady trading partners in Asia, Africa, the middle east, Europe, and South America throughout the years. Our innovative designed production line and every single unit of the production line are economical and practical.

ZTZG is one of three executive directors of 'China Steel Structure Association' 

and one of China's top ten pipe making machinery brands. 

With over 20 years of sales and R&D, ZTZG has acheived multiple China's first along with

several patents that lead the pipe making industry in China. We look foward to make

better, steadier, and more economical machines in the future.
