VSSJA-1(BF) type single flange loose sleeve limit expansion joint

BF (VSSJA-1) single flange limit expansion joint compensates the possible axial displacement of the pipe, and can greatly reduce the axial thrust of the pipe during operation, thereby extending the life of the safe operation of the pipeline and line. The single flange loose sleeve limit expansion joint can prevent the result of excessive displacement due to leakage or damage in the compensation pipe joint. It is mainly used to absorb the axial displacement and axial pressure of the thrust pipe to relieve the loose sleeve connection. One end of the pipe flange is connected to the other side. Inconsistent solder connections. Install and maintain pipeline valves that can be easily dismantled and overcome the adverse effects of settling on pipelines. BF (VSSJA-1) single flange limit expansion joint is used to transport water, fresh water, hot and cold water, drinking water, sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, and the temperature is not higher than 250 degrees Media such as high steam and particulate powders.

Data sheet:

How is the production process of single flange loose sleeve limit expansion joint composed?

In the production of single-flange loose-sleeve limit expansion joints, each enterprise uses different methods and production processes, but the basics are similar. The production of single-flange loose-sleeve limit expansion joints is generally prepared by preparing Raw materials, processed, painted after processing, inspected before leaving the factory, and then transported by logistics.

Production preparation process of single flange loose sleeve limit expansion joint. The production preparation process refers to the production technical preparation process carried out before the power transmission joints and expansion joints are put into production. Such as technology, process equipment, raw material preparation, labor organization preparation and ideological preparation. crafting process. The technological process refers to the process of changing the shape, nature, weight, appearance, etc. of the labor object to make it a finished product according to the technological process. It is an essential part of the production process. The manufacture of blanks, the processing of parts, and the assembly of power transmission joint products are all technological processes. inspection process. The inspection process refers to the process of checking whether the power transmission joint products meet the technological requirements of the power transmission joint products after being processed. It is the process of guaranteeing, supervising and controlling the quality of power transmission joint products, which is composed of inspection procedures. For compliance with the standard, the inspection process includes all quality inspections of work-in-process, semi-finished products and finished products. transport process. The transportation process refers to the process of transferring and transporting the processed power transmission joint product objects, which is composed of transportation procedures.
