[# Today's Xiaoman#] When the sunny day is warm and the green shade and the grass is better than the flowers; Today, the small full solar term is ushered in. Wheat grains are full of rice, silkworms are newly cocooned and mulberries are ripe. The word "full" in small full not only means the fullness of wheat grains in the north, but also relates to the abundance of rain in the south. All things are full of life and leisurely. At this time, it was the wheat filling period, and the wheat grains seemed to be full. In fact, they were only "half full" and not mature, so they were called "small full". ① At 15: 59 today, Xiao Man arrived. ② Rain hits banana, plum yellow apricot fertilizer, as the second solar term in summer, Xiao Man is full of summer amorous feelings; ③ Xiao Man Xiao Man is full of wheat grains. At this time, the northern region is small.

Beneficiary Mining Technology-Quick-connect Spiral Drill Pipe Series
Quick-connect spiral drill pipe is developed on the basis of absorbing the advanced production technology of Germany and integrating the latest research results of our company. The drill pipe body is made of high-pressure seamless alloy steel pipe, and the spiral blade is made of high wear-resistant T-shaped steel strip, which is prestressed and wound and welded. The drill pipe joint is made of high-quality medium-carbon alloy steel, which is subjected to vacuum conditioning and high-pressure forming. This series of products adopts four-way or six-way quick connection, which is automatically locked by spring pins when used, and is equipped with U-shaped or semi-ring anti-release pins to make the torque of the drill pipe reach the best state. This series of products are mainly used with portable or hand-held drilling rigs. The drill pipe is light in weight, quickly connected, and the slag discharge speed is fast, which greatly improves the work efficiency, so it is called quick-connect spiral drill pipe. This series of products are widely used in the drilling construction of water exploration and gas exploration under the geological conditions of coal seam and near coal seam, and are divided into water type and water type. Common specifications and performance parameters are shown in the following table: quick-connect spiral drill pipe common specification model performance parameter table line number specification model mm theoretical torque N.m connection mode spiral diameter rod diameter length joint size 1 Ф 28 Ф 18500~3000F12 × 12150~200 square connection 2 Ф 30 Ф 18500~3000F12 × 12150~200 square connection 3 Ф 32 Ф 18500~3000F12 × 12150~200 square connection 4 Ф 38 Ф 21500~3000F14 × 14100~350 square connection 5 Ф 40 Ф 21~22500~3000F14 × 14100~350 square connection 6 Ф 42 Ф 22500~3000F13 × 13200~350 square connection 7 Ф 69 Ф 25~27500~3000F18 × 18250~350 square connection 8 Ф 69 Ф 25~27500~3000B20 × 20350~450 square connection 9 Ф 75 Ф 32~42500~3000F24 × 24350~450 square connection 10 Ф 89 Ф 32~50500~3000F26 × 26350~450 Quadripartite Connection 11 Ф 98 Ф 73500~3000B45 × 4510000-12000 Hexagonal Connection 12 Ф 113 Ф 63~73500~3000B45 × 458000-12000 Hexagonal Connection
