Problems with end plate splicing
Thread Content
I’m facing a problem now: the head for TA9, DN900*6.0, has an expanded dimension of φ1160. Due to the material used in TA9, its price is relatively high, and there isn’t much in stock in the market. The width of our own material is 1000+ millimeters, and there are no suitable sheets available from other companies in the same industry. Can this end plate be assembled using 1000+160? GB/T25198 also does not mention the issue of splicing ratios. Are there any specific regulations or standards regarding the ratio of jointing for end plate splicing?
There is no requirement in the standards, but it’s best to communicate with the inspector first to avoid any troubles.
Avoid the opening in the middle; make the edges as large as possible. If the distance from the edge is too short, cracks are likely to occur at the weld area after stamping.
Neither the GB/T150 nor GB/T25198 standards impose any restrictions in this regard, as long as the quality of the molded part and the weld quality are ensured.
