Our company specializes in exporting seamless steel tubes, alloy steel tubes, boiler tubes.When it comes to steel tube products, we will inevitably encounter some professional terms.

The Hold point and Witness point are always found and indicated in the Inspection and Test Plan. They are the construction stages which may need supplementary inspection or verification. See how to use Hold Points and Witness points when inspections or verifications are required. What is it? There are two important inspection actions that must be carried out in respect of the Inspection and Test Plan, they are called Hold Points and Witness points. They are points in the construction stage where inspection or verification is required. Their purpose is to make sure specification requirements have complied accordingly and to proceed for the activities.Why would you want it? The definition of a Hold Point versus a Witness Point: A Hold Point is a mandatory verification point beyond which work cannot proceed without approval by the designated authority, typically the Engineer or Consultant or 3rd Party Inspector. Work cannot proceed until receipt of a Hold Point Release issued by the person(s) whom inspected the work. A Witness Point is an identified point in the process where the designated authority, typically the Engineer or Consultant or 3rd Party Inspector may review, witness, inspect method or process of work. The activities, however, may proceed.

Our company has rich experience not only in products and exports, but also in details, such as Boiler Pipes, Boiler pipes HP, Boiler pipes inspection, Boiler pipes RD, Boiler pipes RI, Boiler pipes SP, Boiler pipes testing, Boiler pipes WP, If you are interested in any of our merchandise or would like to discuss a custom order, remember to feel free to contact us.
