Company Profile

Shandong Jiajiena Metal Products Co., Ltd. was established in 2016 and covers an area of 15,000 square meters. The total assets are more than 300 million yuan. It is a professional company dealing with pipes and plates. The company has passed the IS0 three system certification, and sells stainless steel products such as galvanized, Taigang, Qingshan and other well-known national brands such as Tianjin, Baotou Steel, Baosteel, Yegang, Chengdu, Anshan, Hengyang, etc. all year round. The annual sales volume reaches hundreds of thousands of tons. The company also specializes in the production and production of seamless cold drawn pipes, fine drawn pipes, square and rectangular pipes, special-shaped pipes, precision bright pipes and seamless steel pipes.
1. Our company is a large-scale steel pipe enterprise integrating production and sales. The company has 60 units, 90 units, 140 units and 325 units of hot rolling production lines. Production specifications include 20mm-710mm*2mm-100mm, and more than 3000 operating specifications. Production range: outer diameter: 20mm-710mm, wall thickness: 2mm-100mm. Product materials are as follows: 10#, 20#, 35#, 45#, 16Mn, 27SiMn, ST44, ST52, x42, x52, 15CrMo, 30CrMo, 34CrMo4, 12Cr1MoV, J55, K55, N80, L80, P110, etc. Standard: GB8162- 2008, GB8163-2008, GB3087-2008, GB5310-1995, GB6479-2000, ASTM A53, ASTM A106, API 5L, API 5CT, DIN, JIS, etc. At the same time, the company has five cold drawing machines, ten finishing mills, two automatic straightening machines, and six automatic cutting machines, which can produce the following products: cold drawn seamless pipes, non-standard seamless pipes, cold drawn welded pipes, triangular Pipe, hexagonal pipe, octagonal pipe, oval pipe, horseshoe pipe, outer six inner circle and other special-shaped steel pipes. It mainly produces cold-drawn steel pipes of various specifications with an outer diameter of 8- -219mm, a wall thickness of 0.8- -20mm, and a length of 12m or more, and can also be processed with supplied materials.
2. Ten new precision rolling precision steel pipe units, mainly producing outer diameter: C 10- -219mm, wall thickness: C 1-30mm precision pipe, 20# precision steel pipe, 45# precision steel pipe, GLR15 bearing steel pipe, Q355B precision steel pipe The company has modern standard workshops, advanced precision cold-rolled pipe production lines, and perfect physical and chemical testing equipment. The salient features are: 1. The cold-rolled precision steel pipe has high tolerance and dimensional accuracy, and the product accuracy is controlled to 0.05mm; the smoothness is good; the inner and outer surfaces have no oxide layer, and the inner wall is clean. 2. The comprehensive performance of cold-rolled precision steel pipe is excellent, it can withstand high pressure, cold bending, flaring, flattening does not crack, does not wrinkle skin, and can be processed for various complex deformations and mechanical processing. 3. The promotion and application of precision seamless pipes can save steel, improve processing efficiency, reduce processing procedures and equipment investment, save costs and greatly save machining hours, improve production capacity and material utilization, and at the same time help improve product quality and reduce cost.
