A core pipe is a rolled metal product in the form of a straight, hollow profile with a round cross-section and uniform nominal wall thickness. Steel core pipes are manufactured strictly in accordance with GOST 6238-77 from steel grades: K, M, D. The outer diameter of the pipes is 25-146 mm. The thickness of the tube wall is 3-5 mm. The length of the pipe is 1500-6000 mm. The chemical composition of alloys may include: carbon, silicon, manganese, chromium, nickel, titanium, sulfur, phosphorus. The total mass fraction of sulfur and phosphorus should not exceed 0.09%. The accuracy of pipe manufacturing can be: - normal; - increased. There should be no seams, caps, cracks, flaws or sunsets on the outer and inner surfaces of the pipes. Individual minor defects are allowed (nicks, dents, scratches, a thin layer of scale, traces of stripping and small films), if the depth of their occurrence does not take the wall thickness beyond the minimum permissible values. Properties: - thread pitch – 4 mm; - working coil height – 0.750 mm; - temporary resistance 638-657 N/mm2; - yield strength 373-758 N/mm2; - relative elongation of at least 12-16%; - explosion safety, fire safety, non-toxicity, electrical safety, radiation safety; - high thermal conductivity. GOST 6238-77 pipe is used in geological exploration drilling for fastening wells and core sampling.
