SSAW Pipe

    Edge milling machine of dsaw pipe is divided into XB series edge milling machine, self-driven milling machine, is a new generation of milling, the domestic alternative planing machine's most fantastic equipment.     Use of edge milling machine:     Commonly used in the boiler, pressure vessel manufacturing industry, shipbuilding, electricity, petroleum, chemical machinery, engineering machinery manufacturing, all kinds of low carbon steel, stainless steel and aluminum plate in the welding before the groove processing, type groove can be a milling molding, compared with the planing machine, with low prices, low energy consumption, high efficiency, high brightness, easy operation and maintenance and other advantages.     Edge milling machine and the traditional milling machine:     The rail device is detachable, and after heat treatment, the bed structure is reasonable, the milling head is running more stable and reliable, its...

    1. The quality inspection of the dsaw pipe shall be carried out by the technical quality supervision of the supplier.     2. The supplier must ensure that the delivery of the dsaw pipe meets the specifications of the corresponding product standard. Providers have the right to check and verify the corresponding product standards.     3. DSAW pipe inspection items, sampling quantity, sampling parts and test methods, according to the corresponding product standards.     4. DSAW pipe should be submitted in batches to check, the batch rules should be consistent with the corresponding product standards.     5. DSAW pipe test results, one does not meet the product standards of the rules should be unqualified pick out, and from the same batch of dsaw pipe, take the double the number of samples, reassessment of unqualified items. The results of the re-inspection (including any of the requirements of the project test) failed, then ...
