Hebei Shengtian pipe fittings Group Co., Ltd. in the main distribution of flange, elbow, three-way, four-way, elbow, intubation, different diameter pipe, high-pressure pipe seamless steel pipe, etc. products, we constantly updated products, at the same time, follow up product news update, if you have a pipe product knowledge confusion please timely attention to our website, every day we will update news information products.
Big head appearance should not crack, heavy leather, wall thickness should be greater than the large diameter end of the pipe wall thickness. Head size roundness should not greater than 1% of the corresponding end of the outer diameter and allowable deviation for 3mm; concentric reducer center of the two ends of the line should be coincident, the eccentric value tolerance of + / - 5 mm.
Reducer used material is a class with special electrical, acoustic, thermal, mechanical, chemical and biological function of new materials, is an important basis for the field of biological technology, energy technology and other high technology and national defense construction materials, but also to transform some of the traditional industrial, such as plays an important role in agriculture, chemical industry, building materials and other.
Size the head cutting productivity, tool durability, surface roughness, cutting force and machining hardening has great influence, the reasonable selection and improvement of tool geometric parameters is an effective way to guarantee the processing quality, improve the efficiency and reduce the cost of. With the rapid development of aviation, aerospace, petroleum, chemical industry, metallurgy and food industry, the stainless steel material has been widely used, and large head material, because of the toughness, high temperature strength, low thermal conductivity, cutting plastic large deformation, serious work hardening, cutting heat, difficult heat dissipation,, resulting in stainless steel size at the cutting head of a high temperature, cutting chip adhesion edge serious, prone to bue not only intensifies the head wear, but also affect the roughness of machined surface.
Making big head of the materials need some special raw material production, these materials to strict selection and control, raw materials to select the appropriate, otherwise produced welded elbow wouldn't have quality assurance. According to the need, a circular ring shells can be cut into four 90 101 elbow or six 60 DEG elbow or other specifications of the elbow, the process combined used in the manufacture of big head diameter and bend diameter ratio greater than 1.5 any specification of big head, is ideal method for the large size of the head of the manufacturing.
My company sincerely welcome friends from all circles at home and abroad to visit the guidance, and seek common development.
