b br The construction is convenient and fast. It avoids on-site welding wire threading or rolling groove operations. As long as special clamping tools are used, the clamping connection can be easily completed, saving time, effort and cost. And the installation was successful in one go
b br The double-headed double-sealed clamp-type acoustic detection tube and spiral acoustic detection tube (flange-type acoustic detection tube) products comply with the requirements of the Ministry of Communications of the People's Republic of China in
is the national standard implementation standard (/
). The various specifications of acoustic testing tubes produced by our factory are not only It can meet the requirements of the standard, and each indicator has been greatly improved, and has obtained the test qualification report from Hebei Daoqiao Testing Center<
