Shaanxi Peter International Trade Co., Ltd. Factory Tour

• Raw Material Procurement and Preparation: This is the first step in the entire production process. Suitable materials such as cast iron, carbon steel, stainless steel, etc., are procured according to requirements. Before procurement, the raw materials undergo quality inspection, including chemical composition analysis, physical performance testing (such as tensile strength, hardness), and dimensional checks.
• Forming Processing: The purchased raw materials undergo cutting, preheating, heat treatment, etc., to facilitate subsequent processing. There are various methods of forming processing, including forging, casting, cold heading, stamping, welding, etc. Forging and casting are two common forming methods, including free forging, die forging, sand casting, and precision casting.
• Machining: Semi-finished products from forming processing need to undergo machining, including turning, planing, milling, drilling, internal thread processing, etc., to meet different specifications and requirements.
• Surface Treatment: Flanges after machining require surface treatment to enhance appearance and durability. Common surface treatment methods include polishing, sandblasting, painting, etc.
• Assembly and Inspection: Assembled flanges after surface treatment undergo quality inspection. Inspection includes pressure resistance, temperature resistance, sealing performance, etc., to ensure that the products meet relevant standards and requirements.
• Packaging and Shipping: Qualified flanges after quality inspection are packaged for transportation and storage. Finally, packaged flanges are shipped to customers.

Established in 2007 by Mr. Kong Xiang Dong, Shannxi Peter International Trade Co., Ltd has undergone significant technical expansion since its inception. This expansion involved acquiring various machinery and equipment essential for manufacturing circular wrought parts, including a 3600-ton hydraulic press, a 5-meter ring rolling machine, BT and 5-ton electro-hydraulic hammers, 2 to 5-meter vertical lathes, a 5-meter numerical control drilling mill, and a heat treatment oven.

With these advanced capabilities, the company boasts the capacity to produce approximately 15,000 tons of circular wrought parts and 12,000 tons of finished flanges and pipe fittings annually. These products are crafted from a variety of materials such as stainless steel, carbon steel, alloy steel, and dual-phase steel, encompassing a diverse range of types and specifications.

Shannxi Peter International Trade Co., Ltd has earned international recognition for its products, which are exported to 28 countries and territories worldwide, including Japan, the USA, France, Germany, and Italy. The company holds the necessary rights to engage in export activities, enabling direct negotiation and fulfillment of overseas orders.

Moreover, the company excels in producing standard flanges and pipe fittings in compliance with both domestic and foreign standards such as JIS, ANSI, EN, DIN, BS, and GB. Additionally, they possess the capability to manufacture circular wrought parts, non-standard flanges, and pipe fittings based on customer-provided drawings or samples. This adaptability allows Shannxi Peter International Trade Co., Ltd to effectively cater to a wide array of customer needs and specifications.
