Production processes are mainly divided into forging, casting, cutting and rolling. The cast flange has accurate blank shape and size, small processing capacity and low cost, but there are casting defects (pores, cracks and inclusions); The internal organization streamline of the casting is poor (if it is a cutting part, the streamline is even worse);

Marking, packaging, transportation and storage 1) Signs The rubber joints shall at least have the following permanent marks: manufacturer name, product name, product specification, model and working pressure. 2) Packaging Packaging shall be carried out according to the agreement between the supplier and the buyer. A valid product certificate shall be attached to the package,

Wedge gate valve can bear high pressure because its sealing surface is at an angle to the vertical centerline and has good sealing. Generally, the valve stem of wedge gate valve is subject to quenching and tempering and surface nitriding treatment, which has good corrosion resistance and scratch resistance; The gate and valve seat seal

Body: Ductile iron GGG40/GGG50 Disc: Ductile iron+EPDM/NBR Stem: Stainless steel Size: DN40-DN600 The opening and closing part of the wedge gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The wedge gate valve can only be fully opened and fully closed, and is not suitable for

Different from parallel gate valves, wedge gate valves also have wedge single gate valves. The two sealing surfaces of the most commonly used wedge gate valve form a wedge, and the wedge angle varies with the valve parameters, usually 50. The gate of wedge gate valve can be made into a whole, which is called

The Filter Y type-Screen is an attractive and economic solution for Landscape application as well as Municipal application. It varies from a small size of ¾” to large size of 2-1/2″. By utilizing the Y shape, will fit most of the installation infield. The Y filter is the perfect solution for fertilizer usage where soluble

1. Raised surface pressing surface: Features: simple structure, easy processing, easy loading and unloading, easy anti-corrosion lining; Use: the pressing surface can be smooth and suitable for occasions with PN less than or equal to 2.5MPa; With grooves (2 ~ 4, width x depth of 0.8mmx0.4mm, cross section of triangular circumferential groove), the gasket is

1. When the flexible rubber joint is installed in the pipeline, it must be in a natural state, and the product shall not be deformed artificially. When the pipeline medium is acid-base resistant, oil resistant, high temperature resistant and other special materials, the joint one gear higher than the working pressure of the pipeline shall

1. It is forbidden to install the rubber flexible joint beyond the displacement limit. 2. When installing rubber joints on flat ground, in the air and vertically, the actual working axial displacement pressure of the rubber joints shall be less than the supporting force of the pipeline, otherwise anti pull off devices shall be installed

Rubber joints are also called rubber pipe soft joints, flexible rubber joints, rubber soft joints, flexible rubber joints, high-pressure rubber joints, rubber shock absorbers, compensators, etc. According to the connection mode, it is divided into loose flange type, fixed flange type and threaded type; According to the structure, it can be divided into 5 kinds:
