Carbon steel flat welding flange PN10 gb hot coil steel special-shaped flange custom processing DN1000 welding flange
Main functions of flange:
1, pipe failure, easy to disassemble detection;
2. Connect the pipeline and keep the pipeline with good sealing
performance;
3. If a certain section of pipeline has problems, it is easy to
replace a certain section of pipeline.
Flat welding flange in production and use has certain technical
requirements and technical parameters, according to a certain way
and method of production and processing:
1. The butt weld of the ring shall be subjected to post-welding
heat treatment and 100% ray or ultrasonic inspection, and the ray
inspection shall meet the grade II requirements of JB4730, and the
ultrasonic inspection shall meet the grade I requirements of
JB4730.Butt welding flange adopts certain welding standards and
technology production and processing, in line with the
corresponding production standards and requirements of ***.
2, the production of flat welding flange steel plate should be
ultrasonic inspection, no delamination defects, to ensure good
quality and performance problems, in accordance with certain
quality requirements of production and inspection, to ensure that
the production and use of steel plate no quality problems;
3, should be along the steel rolling direction cut into strips,
bending welding into a circular ring, and make the surface of the
steel ring cylindrical.The steel plate shall not be directly
machined into a neck flange in the production of the joint flange,
and a certain technology shall be used for production and
processing.
