What is the content of cementing sludge head inspection? Cementing head is a very important device in the cementing operation. If the quality of the cementing head is not up to standard, the cementing quality may be affected. Therefore, the cement head needs to be tested after leaving the factory.

(1) Size inspection of cementing water and mud head

When the cement head production, should be tested, the first test is the size of the cement head test is qualified, there are more types of cement head, each cement head has a lot of sizes, so it is very necessary to test the size of the cement head after the production of the main purpose of testing the size of the cement head has two: one is to test whether the size of the cement head meets the specified standards; The second is to check whether the size of the cement head is the size required by the customer.

(2) Detection of thread connection of cement head

After the completion of the well cementing head production, the thread detection should also be carried out according to the inspection standard, the type of cementing head is different, the inspection standard of the thread is also different, for example, the inspection standard of casing or tubing connection thread is GB/T9253.2, and the inspection of drill pipe connection thread is in accordance with GB/T22512.2. If other forms of connection thread are used, other inspection standards are required.

(3) Testing the overall sealing performance of the cement head

The sealing performance test of cement head is also one of the very important test contents, which is mainly to test the sealing performance with water to see whether the test pressure meets the seal test pressure provisions. The rotating cement head is also tested for rotating performance.

(4) Cement head material test

In addition to the above testing, the material of the stressed parts should also be tested. The main testing content includes tensile strength testing, hardness testing, and impact absorption energy testing of the metal materials used by the parts under impact load.

When the cementing head test is completed, it is necessary to put a sign in the obvious position of the cementing head, including product model, working pressure, manufacturer name or registered trademark, product number and factory date.

When the cement head is produced, it is necessary to carry out strict testing, meet the specified standards, meet the customer's standards, and is a qualified product. A good product can stand the test of the market, and the market is the only standard for testing the product.
