Introduction of hydrostatic testing for pipe fittings

A hydrostatic test is a way in which pressure vessels such as pipelines,plumbing, gas cylinders,boilers and fuel tanks can be tested for strength and leaks.The test involves filling the vessel or pipe system with a liquid,usually water,which may be dyed to aid in visual leak detection,and pressurization of the vessel to the specified test pressure.Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss.The location of a leak can be visually identified more easily if the water contains a colorant.Strength is usually tested by measuring permanent deformation of the container.

Hydrostatic test for large diameter bend in Haihao Group

Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then re-qualified at regular intervals using the proof pressure test which is also called the modified hydrostatic test. Testing of pressure vessels for transport and storage of gases is very important because such containers can explode if they fail under pressure.

Hydrostatic test for large diameter custom pipe bend

Recently,we did hydrostatic testing for large diameter custom pipe bends according to the requirements of customers in Kuwait.The test pressure is 1.5 times the maximum possible working pressure.In the end,our products successfully passed the hydrostatic test and met the customer’s requirements.

We are trying to serve the best quality,Haihao Group manufacture steel pipes,butt welding pipe fittings, forged pipe fittings and flanges products more than 30 years, our quality inspection department can carry out the hydrostatic test as per clients requirement.If you have any questions,please email us:sales@haihaogroup.com
