precision welded tubes

Way of baling machine precision steel tube length is higher than or equal to 6 m, each bundle of at least eight tie belt, divided into 3 groups, get into the 3-2-3; Precision steel tube length less than 6 m, each bundle of at least five tie belt, divided into 3 groups, get into the 2-1-2; (FIG. 1 for precision steel tube length is higher than or equal to 5 meters away from tube precision steel tube bundling machine strip parts plan) precision steel tube length is higher than or equal to 3 m, tie belt type at least 3 per bundle, divided into 3 groups, get into the 1-1-1. Figure 1 is higher than or equal to the length of 6 meters away from the tube precision strip steel banding machine parts plan have special requirements, can add four on single precision steel pipe, plastic spring or plastic ring spring or circle line should be strong, can't happen in transport link loose, fall off.
Vessel packaging hot rolled or cold drawn seamless stitching precision steel tube, the outward appearance fine polishing of hot rolled stainless steel precision tube, can choose vessels (such as plastic box and wooden case packing). After precision welded tubes packing vessel net weight should meet the requirements of table 1. Through consultation between both parties, big net weight of each container can be increased. Precision steel tube into vessels, containers of cardboard, plastic film, or other inner chamber should be fitted waterproof sheet. Vessels should be sealed is not suitable for leakage. For vessel packaging precision steel tube, should be within the vessel with a sign. In the vessels to the outer surface, should also be a sign. Cold drawn steel tube, cold rolled steel pipe generating set is made of cold rolled steel, cold drawn or cold rolled steel and cold drawn together way of cold drawn pipe fittings manufacturing the complete set of weapons and equipment, is the hot rolled steel tubes and welded steel pipe in finish machining of the generating set.
According to the characteristics of metal material production, pipe specifications, quality standards, project investment and economic benefit, choose a different production process. Cold cold drawn pipe basic process is as follows: the tube billet, commonly used pipe manufactured goods for heat pipe or semi-finished processing, pressure pipe and welded steel pipe; Tube billet are prepared ahead of time, including inspection, baling machine, pickling passivation, cleaning, cleaning, and drying in Cold Drawn Tubes processing, coating lubricants, etc.; Cold drawn (cold rolled steel or cold drawn); Manufactured goods roll contains manufactured heat treatment process, straightening, sampling, cutting fore and aft, inspection (human flaw detection) periodically check various, suppression test, anointed with oil, packaging, into the library, etc. Different commodity cast-rolling content has a certain difference.
Baling machine packaging should prevent precision steel pipe damage in the binder and transport links, baling machine sign to unify. The same bundle of precision steel tube which is of the same furnace number, production batch number), and steel grade, the same types of precision steel tube, not mixed furnace (production batch number) baling machine, not a bundle should get into some bundles. Precision steel tube bundles of not higher than 50 kg net each. Can improve customer permission bundle of heavy, but not more than 80 kg. Precision steel tube baling machine for flat end, end solve qi, full-justified side hydraulic steel pipes are separated by less than 20 mm, the length of each bundle of precision steel tube difference less than 10 mm, but according to the order of precision steel tube length usually the length of each bundle of precision steel tube difference less than 5 mm, a bundle of precision steel tube length in long of not more than 10 mm.
Cold drawn tube pipe from generating set manufacturing feature is usually take into production into finished products after cold deformation and cause cold work hardening for many times, so the whole production process to prepare ahead of time by several process flow and deformation process, and having the features of reciprocating cycle system, so the process flow, production time is long, metal materials cost is Cold Drawn Steel Tubes larger, the productivity is low, the general production scale is not big. In generating set at the same time equipped with cold drawing and cold rolling mill are beneficial to give full play to their own advantage, especially for manufacturing stainless steel plate contour alloy pipe and difficult to deformation of rare metal is more effective and necessary.
