What is piping heat tracing?

What is piping heat tracing?

What is piping heat tracing? Pipeline heat tracing is a kind of constant temperature or heating method to prevent the material in the pipeline from crystallizing and solidifying or to meet the process demand, and to keep the material at a certain temperature. Electric heat tracing system is the use of electrical energy into heat […]

Cause analysis of common quality problems in some pipeline connections

Leakage at the threaded connection of the pipe After the pipeline is watered and ventilated, there is moisture and air leakage at the threaded connection for the following reasons. (1) The processing of the pipe’s fillet does not meet the requirements, and the fillet is too deep and worn, causing leakage at the threaded connection. […]

Why is the stainless steel pipe subjected to solution treatment annealing?

The austenitic stainless steel is softened by solution treatment. Generally, the stainless steel pipe is heated to about 950 to 1150 ° C for a period of time, so that the carbide and various alloying elements are sufficiently uniformly dissolved in the austenite, and then rapidly quenched and cooled. Carbon and other alloying elements are […]

What is a High-Pressure Pipeline?

Pipelines typically operate at pressures ranging from 70 to 100 bar. As a general rule, the initial compressor stations for pipelines require two-stage compression for boosting pressure from 40 to 140 bar, while intermediate compressor stations require single-stage compression from 100 to 140 bar. Some pipelines operate at high pressures. High-pressure pipelines are defined as […]
