1. Difficulty in repairing high-pressure pipeline leakage

  ❗Difficulty in sealing: High pressure means that the medium has huge energy, and the liquid gas inside the pipeline will spray out from the leak point at a very high speed. It is simply estimated that a liquid with a pressure of 1 kg will spray out of the air at a height of about 1 meter. Any maintenance measures (such as clamps, repair welding, and injection of sealants) must be able to withstand this pressure shock and form an absolutely reliable seal to prevent the medium from breaking through the seal again.
  ❗Energy release danger: Leakage itself is a huge safety hazard. High-speed jetting media (especially gas or steam) have a strong impact force that can cut metal and damage human tissue. Maintenance operations need to be carried out in extremely dangerous environments.
  ❗Difficulty in maintaining pressure: For situations where pressure plugging is required (maintaining pipelines under pressure without stopping water), any operating errors when operating near the leak point may cause the leak to expand or cause a larger rupture. The process of installing clamps or injecting sealants itself requires superb technology and special equipment to resist pressure. If the selected half joint cannot withstand the corresponding pipeline liquid pressure, it will cost a lot of manpower to install it and then leak again, or even explode, which will bring immeasurable losses.

2. why choose carbon steel half joint

Steel has long been considered one of the most useful materials in the construction and engineering fields due to its excellent mechanical properties, including the ability to withstand tensile and compressive loads. Also in the case of a high-pressure pipeline leak, here refers to a pipeline with a pressure greater than 16 kg, a carbon steel half joint is the right choice, and the following is an analysis of several aspects.

1. About the compressive strength of carbon steel half joints

Compressive strength is the ability of a material to resist compressive forces. It defines how steel behaves under compressive loads that attempt to deform or cause it to fail. This is for carbon steel half joints in steel structures, because the material must withstand the squeeze of a large amount of liquid inside the pipeline without the risk of fracture and explosion. The unit of compressive strength is usually published in megapascals (MPa), bar, kilograms, and other specific pressure measurement units, and uses engineering measurement test standards.

Yield strength refers to the maximum stress that a material can withstand within the deformation safety zone, which is critical to the performance of the structure. These properties help material and component design decisions to ensure that operating loads can be sustained without mechanical failure.

The following is a stress analysis diagram calculated by the tool, in which a force of 20MPa is applied to the interior of the high-pressure half joint. From the results, its yield strength is 282.7, and the maximum stress change point result is 0.000848, which is far less than 282.7 and is within the safe value range.

2. Advantages of Carbon Steel Half Joints in Repairing High-Pressure Pipelines

It is the combination of high compressive strength, high tensile strength and durability that allows steel to actively participate in the work of maintaining pipelines. The reliability of steel under extreme stress conditions makes it the only choice for industrial pipelines and high-pressure pipelines in buildings. Carbon steel has a compressive strength between 250 MPa and 350 MPa. Because the steel skeleton can maintain the internal structure of the pipeline and ensure that the half joint itself does not produce too much deformation and risk of bursting when the liquid inside the pipeline gushes out.

In addition, steel can withstand large loads and bend without breaking. Steel is easy to cut and weld, which is an additional advantage in the event of a disaster. Steel can also help keep structural components reliable and corrosion-free due to corrosion-resistant HSLA steel. This material is ideal for structural steel engineering because it is both strong and lightweight. Structural components built using this material will be cost-effective and maintain structural integrity.

When a material is subjected to a load that causes a reduction in volume or a change in structure, the shape under compressive load changes. The variation in the degree of deformation is caused by the material's compressive strength, elasticity, and the time period over which the material is subjected to the load. For most metals, deformation may appear as elastic deformation (i.e., reversible deformation) or plastic deformation (i.e., permanent changes in the structure). Evaluating these factors ensures that the continued load on the material does not cause structural failure.

For the 20 kg half joint produced by the tool, under the pressure of 20 MPa applied inside the pipe, the deformation value of the half joint is 0.00000973 mm. This value is very low, and almost no deformation occurs, which is due to the professional design results of Baoshuo pipe fittings.

Compression and tension are forces that can be applied to a material; compression reduces the size of an object by pushing against it, while tension increases the size of an object by pulling it apart.

It is important to understand the effects and interactions of these forces on materials. Although tension and compression have opposite functions, they have a great influence on the structure of a material. Tension applies an object outward, pulling it apart, and this is the force applied to the Baoshuo high-pressure half joint when the liquid leaks inside the pipe, while compression shortens and compacts the material. Depending on the composition and structure, materials have certain mechanical properties, such as tensile strength and compressive strength, which determine how much force the material can withstand. This relationship is important in design engineering because the mechanical properties of the material determine the ability of the component to withstand various loads without failure.
