​Diaphragm valve is a stop valve that uses a diaphragm as an opening and closing part to close the flow channel, cut off the fluid, and separate the inner cavity of the valve body from the inner cavity of the valve cover. Diaphragms are commonly made of elastic, corrosion-resistant, non-permeable materials such as rubber and plastic. The valve body is mostly made of plastic, fiberglass, ceramic or metal rubber-lined materials. It has simple structure, good sealing and anti-corrosion performance, and small fluid resistance.

The stainless steel ball valve only needs to be rotated 90 degrees and a small rotational torque to close tightly. The completely equal valve body cavity provides a straight flow path with little resistance for the medium. The main feature of the ball valve is that it has a compact structure and is easy to operate and maintain. Stainless steel ball valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The ball valve body can be integral or combined.

Hydraulic pipe clamps can be divided into many types according to their structure, application and material, among which the more common ones are the following:

Stainless steel tees are pipe fittings and pipe connectors. Used where main pipes need to branch. Stainless steel tees are divided into equal-diameter and reducing-diameter tees. The ends of the equal-diameter tees are all the same size; the pipe ends of the main pipes of the different-diameter tees are the same, and the pipe ends of the branch pipes are smaller than the pipe ends of the main pipe.

According to chemical (HG) industry standards: integral flange (IF), threaded flange (Th), plate flat welding flange (PL), neck butt welding flange (WN), neck flat welding flange (SO), socket welding flange (SW), butt welding ring loose flange (PJ/SE), flat welding ring loose flange (PJ/RJ), lined flange cover (BL(S)), Flange cover (BL).

The main difference between stainless steel elbows and carbon steel elbows is the material difference. The chemical composition contained in them will keep the surface of the elbow from rusting and corrosion for a long time.

The stainless steel head is a threaded connection, usually composed of two parts: the head and the thread. Stainless steel large and small heads are widely used in machinery, aviation, automobiles, construction, instrumentation and other fields.
The size and length of stainless steel heads are determined according to different specifications. For example, M4 × 0.7 has a thread length of 7mm, a head diameter of 7.6mm, and a head thickness of 3.2mm. The thread length of M24 × 3.0 is 36mm, the head diameter is 36mm, and the head thickness is 18mm.
