Acceptable Design for Unequal Wall Thickness

Internally, either a straight bore followed by a 30° slope or a taper bore at a maximum slope of 1 to 4 for a minimum distance of 2 times the pipe minimum wall are required. The surface of the weld can also be tapered to accommodate differing thickness. This taper should not exceed 30°. It may be necessary to deposit weld metal to assure that these limits are not violated. Below some tables with acceptable design for unequal wall Butt weld pipe fittings, Butt weld fittingsPipe standards define these wall thicknesses:SCH 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160, STD, XS and XXS. (S following a number is for stainless steel. Sizes without an S are for carbon steel.) Higher schedules are heavier, require more material and are therefore more costly to make

Difference between Seamless and Welded Tube & Pipe

Advantages of welded tubes & pipes. Lower cost compared to the equivalent seamless alternative. Short lead time. Better surface finishing of outside and inside, the internal material surface for welded tubes can be checked prior to manufacture. Thinner wall thickness, and more uniform. Drill Pipe and Heave Weight Drill Pipe - Enpro PipeHeavy weight drill pipe is a medium-weight drilling pipe, (referred standards in API SPEC 7-1). It has bigger wall thickness than common drilling pipe and smaller than drill collar. The tube is connected with special length-added drill pipe joint (integral heavy weight drill pipe is made up of tube and tool joint). INVESTIGATION FOR SHEET WIDTH AND THICKNESS INVESTIGATION FOR SHEET WIDTH AND THICKNESS DURING PIPE MANUFACTURING BY ROLL FORMING IN A ROLLING MILL Received:26 October 2014 / Accepted:17 November 2014 that welds pierce 100% of the pipe wall and make a very strong bond of the pipe material.

What Is Bevel In Welding And When It Is Used? -

Bevel in welding is an angled flat surface at the end of the material. This opening made by gives the welder access to the total thickness of the material wall and allows him to create a uniform weld using multiple passes which guarantees the mechanical properties of the materials. A root pass is also created at bevels base, forming a place Wuxi Pingyu Heavy Industry Co., Ltd. - China Welded Pipe Feb 10, 2017 · Our main products as follows:LSAW welded pipe, square/rectangular steel tube, steel sheet pile.
