Products grade:

At present, our malleable iron pipe fittings products are divided into three series according to their product design standards: heavy duty, middle type and light type
Heavy duty products: products that fully comply with the national standard GB/T 3287-2011/ISO49/EN10242. The product’s working temperature is 200℃ and the working pressure is 1.6Mpa. Tensile strength>330Mpa, elongation>8%, hardness<150HB. Heavy duty malleable iron fittings are FM approved and UL listed.

Middle type products: malleable iron pipe fittings that meet the standards of established enterprises. Its working strength standard fully meets the national standard, but in order to save costs, it is made smaller in size and thinner in wall thickness. In terms of malleable steel production technology, it is very difficult to process the product thinner while ensuring the use standards. It is easy to have through holes, and its strength and plasticity are difficult to guarantee. Jianzhi achieves this with its industry-leading technical strength. met this requirement. Our enterprise-standard products have successfully reduced product costs while ensuring usage standards, providing customers with more competitive price options.

Light type products: In order to meet the price needs of lower-end customers, We have developed an enterprise standard round edge series of products. Like the enterprise standard square edge products, the round edge products can fully meet the usage intensity required by national standards. At the same time, because the mold design of round-edge products requires low filling capacity and easy mold removal, its manufacturing cost is further reduced. Therefore, we can provide products with the most competitive prices in the industry to meet market demand while ensuring the use of standards.

The difference between three type products

Light type is the round edge products and the weight is lightest so the price is the cheapest one. Middle type malleable iron pipe fitting is square edge products same as heavy duty but lighter than heavy duty BMI fittings. Heavy duty MI fittings are the heavest type with FM approved and UL listed. No matter which type, the malleable iron fittings can meet the national standards.
