Straightsteel pipe, general welded pipe: general welded pipe is used to transport low pressure fluid. Made of Q195, Q215A, Q235A steel, Q235B carbon. It can also be manufactured by easy welding of 0317 standard model 6012 and steel 755 mild steel. The steel pipe is subjected to experiments such as water pressure, bending and flattening, and has certain requirements on the surface quality. Usually, the delivery length is 4-10 m, and the fixed length (or double rule) is often required for delivery. The specification of the welded pipe is expressed by the nominal diameter (mm or inch). The nominal diameter is different from the actual one. The welded pipe has two kinds of ordinary steel pipe and thick steel pipe according to the specified wall thickness. The steel pipe is divided into two types according to the pipe end and the thread. The welding process of submerged arc welded straight seam steel pipe is submerged arc welding technology, which uses filler welding and particle protection flux submerged arc. The caliber of the production can reach 1500mm. LSAW is the English abbreviation for submerged arc welded straight seam steel pipe. The production process of submerged arc welding straight seam steel pipe has JCOE molding technology and roll-formed submerged arc welding technology. When the diameter is large, it may be rolled with two steel plates, which will form a double weld. Standard GB/T3091-2008 low-pressure fluid steel pipe production standard, GB/T9711.1-2 -1997 oil and gas steel pipe production and use standards can be implemented, and can also implement the US API 5L pipeline steel pipe implementation standard. Production material: Q195A-Q345E; 245R; Q345QA-D; L245-L485; X42-X70. The pressure parameters are mainly 2ST/T, S is the yield strength, and T is the wall thickness. Submerged arc welding has been developed to have double-wire submerged arc welding and multi-wire submerged arc welding, and the efficiency is further improved.
COB LED Track Lights are single-optic LED platforms that combine form, function, and visual comfort. Because of its complete flexibility in lumen output and beam angles, it enables optimal lighting designs, including extremely tight accent applications. Designers can customize the light output with interchangeable reflectors to create the ideal environment. In addition, all COB LED Track Lights produced by LiteHome undergo an 8-hour burn-in test before production to ensure that customers receive products in good condition and in a good performance. By choosing LiteHome, you can buy high-quality products at manufacturer prices.
