Piling Foundation Engineering Double Wall Casing Tube

KR Drill supplies a full range of casings, casing joints, Casing shoes, and accessories designed to meet the rigorous demand of fully cased pile boring for large diameter and deep foundations in the most difficult soil conditions including hard rock an other complicated geological environments.MaterialsCasing tube: High strength alloy steel - Q355B/Q460, 1-6 meters Length, 8-50mm pipe Thickness, 620-3000mm as outer Diameter.Casing Joints:Q355B/Q460 Rollingwelding&25CrMo/40Cr Castingunder professional Quenching and Terpering heat treatmentCasing Shoe: High grade steelQ355B/Q460,casing bits with tungsten carbide, likeWS39/BK40,45,50/BA43,62..Casing Driver & Rotator:Q355B/Q460AdvanceCasing tube is different from temporary casing, according to its structure can be divided into single-wall casing and double-wall casing; according to length can be divided into single section 1m, 2m, 3m, 4m, 5m, 6m casing section.Since the casing is equipped with cemented carbide cutting teeth, any soil quality can be adapted, especially when it encounters rock layers, egg layers, isolated layers and so on, so it has a wide range of uses.Construction on soft soil foundation, because the casing will not collapse by first pressing in, so no protective measures are required.In the connection mode of the casing, the button type male / female joint is adopted, and the number of joints varies depending on the casing diameter. This connection method is in line with international standards to ensure the versatility of domestic / international markets
