Products may be modulated, heat handled and completed consistent with purchaser requirements, with exact durability.
Our company has many years of experience in petroleum product processing, and has API certificate and SQ1 certificate. For casing heads, our company can forge 10kg-5000kg forgings, and can forge a variety of materials including 42CrMo, 4140, 4130, 40Cr, 20CrMnMo, 18CrNiMo7-6, 410SS. The product is formed by heating and repeated forging, so that the forging ratio after forging is high, the durability is good, and it is suitable for key accessories of equipment.
