Dear Current Administrators of TBA, Stop erasing posts and topics. All of you. As a regular of TBA who loved it dearly, you have no idea how much it kills me that so many topics were left to the trash without member consent. And it wasn't just drama posts -some of you deleted any post that you didn't like, from roleplays, from anything...you deleted the entirety of A Very Potter Roleplay, as an example. As the creator of that roleplay, I realize it was somewhat of a failure, but the fact that it was erased without my consent is upsetting, and there were a few members who enjoyed it. I realize that there were some things posted on TBA that many of us are not proud of. Drama and the like. But even with that drama, TBA was so, so, important to me, and others. Yet, certain moderators have ignored this and have erased topic upon topic -that showed in the Administrator history. Even if you say it was only a single topic or a single post, the forum has been trimmed down. You say this is only "cleaning up the forum," but it's erasing our history, and I won't stand for it. To those of you who've returned to this forum only to remove things periodically, please stop. It simply isn't fair to those of us who are nostalgic and like looking back, and I know I don't speak of myself alone. With all due respect, LL.

Stainless steel pipe welding methods have their own advantages and disadvantages. How to avoid weaknesses, several welding methods to be combined to form a new welding process to meet people on the quality of stainless steel pipe and production efficiency requirements, is the current trend of stainless steel pipe technology development.duplex stainless steel press checkered plate After several years of exploration and research, combined welding process has made progress, Japan, France and other countries have mastered a certain combination of stainless steel pipe production welding technology. Combination welding methods are: argon arc welding + plasma welding, high frequency.���ڧ�� ���� ������ܧ�ܧѧ�֧��ӧ֧ߧߧ�� ����ѧݧ� 304 Welding + plasma welding, high frequency preheating + three torch welding, high frequency preheating + plasma welding + argon arc welding. Combination welding to improve the welding speed is very significant.Stainless Steel H Beam 304 316L Manufacturer The welding quality of the steel pipe produced by the combination of high frequency preheating is similar to that of conventional argon arc welding and plasma welding. The welding operation is simple and the whole welding system is easy to realize. This combination is easy to use with the existing high frequency welding equipment Convergence, low investment costs, good benefits.ASTM A519 Grade 4140 Cold drawn Seamless Steel pipe
