What Causes The Problems Of Cast Basalt Composite Pipe?

Cast basalt valve factory analysis cast basalt composite pipe before leaving the factory, the cast basalt pipe valve shall conduct mechanical performance test, flattening test and flaring test, and the cast basalt composite pipe shall meet the requirements of specifications and rules.

The quality inspection method of cast basalt composite pipe is as follows: the cast basalt composite pipe is judged from the appearance, that is, in the appearance inspection. The appearance inspection of welded joints is a simple and widely used inspection method. It is an important content of product inspection. It is mainly to find the defects of weld appearance and scale errors.

Generally, after visual investigation, it is checked by means of standard sample plate, gauge, magnifying glass and other things. If the appearance of the weld shows defects, there may be defects inside the weld. Inspection of physical methods: physical inspection methods are methods of measuring or inspecting some physical phenomena. Nondestructive testing is generally used to check the internal defects of data or workpieces. Ndt includes ultrasonic flaw detection, radiographic flaw detection, penetration flaw detection, magnetic flaw detection, etc.

Causes Of Problems In Cast Basalt Composite Pipe

Strength inspection of pressure vessels: in addition to sealing test, strength test shall also be conducted for pressure vessels. There are two common types: hydraulic test and pneumatic test. They can check the weld fineness of vessels and pipelines operating under pressure. The pneumatic test is more flexible and faster than the hydraulic test. The products after the test do not need to be drained, especially for the products with difficult drainage.

But the danger of the experiment is greater than that of the hydrostatic experiment. During the experiment, it is necessary to strictly abide by the corresponding safety skills and measures to prevent accidents during the experiment. Fineness inspection: for welded vessels storing liquid or gas, the non fineness of welds, such as penetrating cracks, pores, slag inclusion, incomplete penetration and loose arrangement, can be found by fineness test. Fineness inspection methods include: fire oil test, water carrying test, water flushing test, etc.

【H】 Ceramic lined pipe

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.

【H】 Cast basalt lined steel pipe

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

【H】 Ceramic Tile Lined Pipes

Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.

【H】 Rare earth alloy wear-resistant pipe

The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.

【H】 Tubes Erosion Shields

Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.

【H】 ASTM A213 T91 Alloy Tube

The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
